Re: [PLUG] Entering accented characters from keyboard

[David Fleck]

How does this work in real life? My PopOS (based on Ubuntu, based on Gnome) has 
this exact mechanism, and the Compose key is set to the left Alt key. The 
Settings page even gives this handy bit of help: "compose key followed by C and 
0 will enter ©".  But when I bring up a terminal and hit those keys at the 
command prompt, I get o, nothing else. If I hold down left Alt while hitting 
both C and o, I get nothing at all. 

What am I missing here?

- What happens if you run that find command by hand?
- What happens if you run that find command without the -exec clause?

The find could be exiting with 1, or it could be passing the exit code
from the rm command. So, let's split that out and see exactly what's
failing.

Re: [PLUG] No space left on device

[David Bridges]

IIRC early in the thread it was said that no partition seems to be out
of space using du / file manager.

I find it unlikely on a desktop system but it is possible that a file
system is out of inodes.

You can use the following to check for inode usage

df -i

Debian Stretch is running the beta version well enough. I do have a

I agree with the "disaster" part. I see very little evidence of

They have a twitter account (which has not been updated in over a year)
which would be a very good place to put status updates. Indeed, that's
what the account had been used for in the past.  This time, no twitter,
no recorded phone messages, no phone response at all, for 10 days and
counting.

See comment above.  Lack of service is very, very bad -- lack 
of information is *inexcusable*.

Did you have a pre-existing cpanel account? If the systems don't accept
my aracnet password, I don't see how to go about setting a new one.

Not sure that I want to, anyway. Given this occurrence of this severe a

them (after 16 years...)

I can now successfully ping a number of their machines, but they reject

From here, the website is "up" in the sense that it returns a formatted

This all depends on the device. If the unit acts as a hub, plugging in 
the device with both drives installed, it's possible that it will be 
presented as /dev/sdc OR /dev/sdc && /dev/sdd.

The only simple way is to test it, and check the dmesg output or tail 
the /var/log/messages file.

If the operating system only sees one device, then the case is doing 
something internal and you likely won't be able to change. You would 
likely be able to guess at it by getting size information on the 
filesystem using parted or fdisk on the presented device.

[PLUG] Semi-OT: Apache reverse proxy URL resolution question

[David Fleck]

This isn't a Linux/UNIX specific question, so my apologies; though the
system involved is OpenSUSE 42.2.

I'm trying to understand how Apache handles URL rewriting for reverse
proxy setups.  In my test case, I've got Apache and Tomcat installed,
straight off OpenSUSE's package repository. My only modification to
Tomcat was sticking a sample .war file into its webapps directory;
my only modification to Apache was allowing browsing to '/' and adding
the proxy settings.  On Apache, the DocumentRoot contains an index.html
file only; on Tomcat, the equivalent location contains the 'sample'
directory. Apache is on port 80, Tomcat on 8080. If I set up the proxy
settings like the following:

ProxyPass /sample  http://localhost:8080/sample
ProxyPassReverse  /sample  http://localhost:8080/sample

Everything works as expected; I browse to http://localhost/sample, and the 
Tomcat sample webapp is displayed.

But...

If I make the following minor change to the proxy settings:

ProxyPass /zample  http://localhost:8080/sample
ProxyPassReverse  /zample  http://localhost:8080/sample

(note the 'z' -- 'zample' not 'sample' in the proxy path) and then browse to 
http://localhost/zample,  I get an Apache 404 error.  If I browse to 
http://localhost/zample/ (with the final slash) it works.  Why the difference 
in behavior?

I've tried every possible combination of putting, or not putting, trailing 
slashes in the URLs in the proxy settings. Reading the Apache documentation, it 
sounds as though this might have done the trick, but it didn't. It doesn't 
change the behavior at all.

One thing in particular that seems weird is that apache access log entries 
generated when I get the 404 error when browsing to http://localhost/zample are:

::1 - - [23/Sep/2017:15:39:52 -0500] "GET /zample HTTP/1.1" 302 - "-" 
::1 - - [23/Sep/2017:15:39:52 -0500] "GET /sample/ HTTP/1.1" 404 981 "-
" 

as though Apache is trying to find the remote path (/sample) on the
local DocumentRoot.  Conversely, when browsing to http://localhost/zamp
le/, the log entries are:

::1 - - [23/Sep/2017:15:36:46 -0500] "GET /zample/ HTTP/1.1" 200 636 "-
" 
::1 - - [23/Sep/2017:15:36:46 -0500] "GET /zample/images/tomcat.gif
HTTP/1.1" 200 1441 "http://localhost/zample/;  (works as expected)

and when browsing to http://localhost/sample (no trailing slash!):

::1 - - [23/Sep/2017:16:13:20 -0500] "GET /sample HTTP/1.1" 302 - "-" 
::1 - - [23/Sep/2017:16:13:20 -0500] "GET /sample/ HTTP/1.1" 200 636 "-
"

HTTP/1.1" 200 1441 "http://localhost/sample/;   (this also works)

To summarize: if the local path element matches the last element of the
remote path, I can browse to a proxied URL either with or without a
trailing slash; but if the local path element does not match the last
element of the remote path, I *must* provide the trailing slash for the
URL to resolve.  

Does anybody know why this is? Is there a way to get apache to treat
the URLs consistently? What's a good resource for this?

You can always try running top on the side while launching LibreOffice 
to watch what is happening. If no CPU spike, pay attention to the memory 
utilization, and you can monitor that as you restart Firefox.

Several things you can check for. The most basic cpmmands are 'top' or 
'htop' and look for a busy CPU, I/O wait, and memory utilization.

Other things that can cause some applications to be slow and others to 
be fast are filesystem related. If you have network mounted drives and 
that connection is not responding, that can appear as a delay.

Since you don't indicate that other applications are having a problem, 
this is hard to guess at, but if you open a browser or new terminal by 
double clicking their icon and it's snappy, I'd suspect filesystem issues.

Of everything behaves the same, then you have a system resource issue, 
and the first commands above may shed some light.

It's been about a decade since I delved into writing perl module tests,
so I'm afraid I don't have much insight to offer here. You could
attempt to contact the maintainers of the Net::DNS package ("Net::DNS
is maintained at NLnet Labs (www.nlnetlabs.nl) by Willem Toorop.") for
assistance.

I tried installing Net::DNS on my laptop, but it installed without
errors. It seems like your problem is in the file ~/.cpan/build/Net-
DNS-1.12-0/t/08-IPv4.t, but I don't see anything in your output that
indicates what specifically might have happened. The version that
installed for me from CPAN was a later one (1.12), which has a
different number of tests indicated for that test file, 91 for me vs.
77 for you.

FYI, my output for that portion of the test suite looks like this:
t/08-IPv4.t ... 81/91 # non-existent \
'bogus.example.com.' resolved: 198.105.254.63 198.105.244.63
t/08-IPv4.t ... ok     

Sorry I can't be of more help here. Testing is great and all that, but
failing mysteriously isn't a whole lot better than no test at all,
IMHO.

You can try brute force on the CPAN command line:
 force  CMDtry hard to do command  
 fforce CMDtry harder
 notest CMDskip testing

so, either 'force install', 'fforce install', or 'notest install' in
this case, I think.

No guarantees that this won't result in compounded problems down the
line, though.

Re: [PLUG] Cheap printer for Raspberry Pi idea

Be careful drawing that much power out of a cigarette lighter. The 
connection will get hotter than a pistol! It is not meant to handle that 
much current for more than a minute or so at time. 3 or 4 amps is a good 
long term maximum, which is still 40 or 50 watts. Been there ... done

[PLUG] DataCenter Systems

[David Phillips]

All:

Recently moved to the area and brought some of my systems that I no longer need 
with me. I figured that someone in the group might be interested.

I have a Brocade ADX1000 load balancer. I bought it new 3 yrs ago and had the 
latest switch firmware on it as of 2015. I also have the class docs for this 
load balancer.
Hoping to get 500.
I also have a beast of a storage server. It holds 36 * 3.5 sas2/sata3 drives, 
it has 64gb ram and 2*4 way intel xeon’s with i7 core. Currently it has 12 * 1 
TB sas drives, 2 of the raid1 the other 10 in raid6. So currently has 7.5tb of 
raid6 storage. 
Hoping to get 2k
Also Have 18 * 3tb Seagate 7200 SAS drives, 50 each or make an offer.

ping me if interested.

You might find the invocation scripts in /etc/bashrc, /etc/profile, or 
/etc/profile.d/*, which are general to all users on the host. In principle, the 
agent should die when you log out, but I've seen some folks out in Google land 
add explicit kills to .bash_logout.

In any case, gpg-agent processes with a parent PID of 1 have been abandoned and 
can be killed. Any /tmp/gpg-* directory older than the last time you logged out 
can be deleted.

Cheers!

Re: [PLUG] Upgrading rooted Samsung Android phone

[David Bridges]

If you device is supported I think that LineageOS is a great option. 
You can see if your device is support at the following link.  

https://wiki.lineageos.org/devices/

By default the device is not rooted but it can be added although I
personally do not have a need for it.

The particular device you mentioned does appear to be supported and
from looking over the information at the following page for the Galaxy
Note 3 (T-Mobile)(hltetmo) the installation of 14.1 (based on Nougat)
should be fairly straightforward.

The biggest decision that you need to assess is what your needs are, and 
other replies have already covered this, so this is a bit of a more 
generic answer.

If you are able to do all your work over command line, ssh is probably 
good enough for you. You will largely need to tunnel back any gui 
applications through your tunnel back to your display and run binaries 
remotely.

If, however, you want to isolate *all* (or nearly so) your traffic from 
the network that you are connected to, you want VPN. This normally 
includes locally run browsers and mail clients. If you don't need this 
functionality, then VPN may not be necessary.

My home network is static enough that I have a pseudo static IP, and I 
have configured OpenVPN for my own use when I connect to any foreign 
hotspot when using my phone, tablet, or laptop. This allows me to 
isolate all traffic through a perceived safe (hey, it's Comcast after 
all) gateway to the Internet, and the VPN also provides me with access 
my internal only services such as ownClound when remote for those pesky 
files that aren't already downloaded to my device.

If your needs are simple and you can do everything over ssh, then stay 
with that, or explore and tinker with OpenVPN and decide if it's for you 
at some point in the future.

[PLUG] Issues with Spam Filters

[david]

All,

I am requesting the help from this list to come up with a viable 
solution for a problem that has now been plaguing me for several weeks 
now. My hosting provider has been blacklisted and they seem to be having 
issues with removing their interface off of the blacklists for several 
providers.

What options are out there for mail service on a short term basis 
(hopefully) I can use in place of my hosting provider? I have an ancient 
Google account that apparently has some sort of service that might be 
grandfathered for this kind of service, but I can't remember what the 
name of it might be.

I'm willing to entertain and consider all options, even paid resources, 
to get my email life back in order. I just need something that is 
reliable and, preferably, backed by users of the list.

Chrome and chromium test for things like self-signed certificates, untrusted 
CAs, and other things. Here's one report:

If you have a way to get data directly from the NAS, you can try

Re: [PLUG] CentOS 7 iso too big to burn...

[David Bridges]

As others have stated upgrading CentOS/RedHat is not really an option
but the options below will allow you to use the ISO to do a fresh
install on the new disk.

I would not copy anything to the new disc that you want to use.  You
can just place the ISO on your current installation and create an entry
to boot into the CentOS 7 installer using your current grub following
the instructions below.

Mount the ISO and copy vmlinuz and initrd.img to your current /boot
partition from the images/pxeboot directory of the ISO.

You can create and entry in /boot/grub/menu.lst that resembles the
information below but it adjusted according to your current
installation.  I would suggest that you not make this the first entry. 

title installer
root (hd0,0)
kernel /vmlinuz
inst.repo=hd:vda3:/CentOS-7-x86_64-DVD-1611.iso
initrd
/initrd.img

The root line should be exactly the same as the other entries in the
file (assuming you put the vmlinuz and initrd.img files in /boot)

You will need to change vda3 to whatever partition the ISO is located
on and them modify that path to the ISO.  You will need to make sure
that you do not rename the ISO or this will not work without additional
parameters.

Reboot your computer and when you see the grub screen press space to
get a menu that shows you all boot options, select installer.

This will boot you into the installer so that you can install to your
new disk.  It will not modify your current bootloader, the install will
install grub2 on the disk you install to (make sure you install to the
correct disk).

Almost all computers will allow you to pick the disk you want to boot
by pressing some key in order to see a list of devices, if not you can
more than likely set it in the BIOS.  In order to be able to use the
new disk as the boot device.  Once you are in the new OS you can have
CentOS probe for your other installation and create an entry for it so
that you can boot it with the following command.

grub2-mkconifig -o /boot/grub2/grub.cfg

This still does not modify the boot sector on your original install. 
If you want to boot your original install (old grub) but also have the
option to boot into the new installation you can run the following
command.

grub2-install /dev/sda (modifying sda to be the device your original
install was on)

These instructions will work but if not done correctly can trash your
system so proceed at your own risk.

I can't speak for Staples specifically, but I recently bought a laptop 
without RJ-45 on-board and successfully used both an old Netgear FA120 
and an Apple USB-RJ45 without any problems.

The only thing to note (if not mentioned elsewhere already) is that most 
of the USB dongles only support 100MB speeds for data transfer. If you 
need speeds exceeding that, you may run into compatibility issues with 
Linux and likely pay a premium for that feature.

Howdy.

You don't provide quite enough information, but I can get you close 
enough that you should be able to figure it out from there.

If you have a RH based system, you will want to use yum to remove the 
oldest one or two kernel RPMs. I'd suggest starting with find out your 
current kernel release, and then listing which kernel images are installed:

$ uname -r # so you know what you can't remove
$ rpm -qa | grep kernel-[2-4]
$ sudo yum remove ${package name from above}

If you are using a Debian based system, it's similar:

$ uname -r # so you know what you can't remove
$ dpkg -l linux-image* | grep ^i
$ sudo apt-get remove ${package name from above}

You just want to be sure to leave your current running kernel and the 
next youngest version (IMO), and the rest can be removed to free up 
space in /boot.

I'm not sure I fully understand what the requirements of your friend are 
at this point. Do they want a WiFi router, or something else?

I've been relatively happy with my R6400 from Netgear[1], but the built 
in OpenVPN doesn't play nice with anything except Windows. There was a 
recent patch that fixed a vulnerability for remote command execution, 
but largely it's been reliable. The last firmware release we relatively 
stable, but one of the previous releases only lasted about 30 days 
before it went haywire and required a reboot. The new one is only about 
4 days old now, so time will tell there.

I have a Linux workstation running behind the router and that receives 
connections for OpenVPN service that is installed there, and works well 
enough for me and all my mobile devices.

True, but the original context was "in automation". GUIs obviously have

What I have to do (on a Mac for the moment) is start the typing, get the

IIRC it's similar in Linux, but the key seems to be Shift.

If you read the script that is referenced by "whowd", there is a test 
for the host keys, and that creation is bypassed because the file 
exists. My apologies for presuming that you would read it more carefully.

Try deleting the zero-byte files, and restart sshd. This should cause 
the script to run those parts to build those files for your system.

No, 0600 is too restrictive for .ssh. You must have the executable flag 
on the .ssh directory so that the processes may traverse down into that 
directory to access the public keys and config file. Else you are forced 
to use password authentication.

Mode 0600 is required for the files within .ssh, however. (Or at least 
most of them.)

 From the ssh-add man page:

DESCRIPTION
  ssh-add adds private key identities to the authentication agent,
  ssh-agent(1).  When run without arguments, it adds the files
  ~/.ssh/id_rsa, ~/.ssh/id_dsa, ~/.ssh/id_ecdsa, ~/.ssh/id_ed25519
  and ~/.ssh/identity.

I take that to mean that it *only* searches for those file names. I base 
this on the fact that I don't use any of those names and I don't get any 
prompt when I run ssh-add directly. If I give the full path and the 
non-conventional name as an argument to ssh-add, it loads just fine.

Alternatively, if you have two of those filenames present, does it load 
both and prompt you for the passphrase of the file you *think* it is 
loading? Doesn't appear so, but I also don't know the contents of your 
.ssh directory (nor should I).

Take a gander at the tool ssh-copy-id which is pretty slick way to copy 
your keys into place.

If the key isn't being recognized, you may have a permissions issue, so 
eyeball the mode for the file and the .ssh directory and make sure it's 
restrictive enough. Too permissive, and I believe SSH ignores the 
directory/files for authentication.

Using the verbose ssh command should help provide some insight as well.

I don't do this extensively, but my solution is pretty straight forward:

$ bash ~/bin/some-script.sh
^Z
[1]+  Stopped bash ~/bin/some-script.sh
$ bg
[1]+ bash ~/bin/some-script.sh &

At this point it just runs in the background, but the caveat to mention 
is that I believe the terminal / shell that you executed the script in 
must stay open until the script completes, or it dies with the closing 
of the TTY.

Yes. Running this command (it may be /usr/sbin/showmount on your
machine) and posting the output will be helpful.  

It looks to me as though the NAS isn't configured quite right. You need

NFS, sure, because they generally get mounted explicitly in /etc/fstab
or similar.  I think that's an extra step that is missing here *if* the
original poster wants to use simple operations like 'cp' -- as noted,
that only works on locally-mounted file systems.  

However, what the original poster really wants to do doesn't depend on
opening that particular can of worms. He should concentrate on figuring
out the right rsync command (shouldn't be that hard) or the right scp
command (as also mentioned earlier).

I have an aging T61 that exhibited random lockup / reboot cycles as 
well. I found that removing the generic nouveau video driver for the 
proprietary nvidia driver resolved my issue.

The other thing that happened with this was a reduction of memory usage, 
a slightly cooler running machine, and a cessation of kernel panics.

Your situation seems to be slightly different and logging in remotely 
during a lockup, or better still before, from another system may glean 
some useful information as I found that my log files simply didn't 
contain anything useful.

Does this happen on _just_ network shares, or all folders? You could

You can try to find out what is holding the device open with lsof, and 
that might hint at what was used to mount it, and then troubleshoot 
things from there. Eject Anyway could lead to a dirty umount or a broken 
shell / utility when it can't see the device any longer.

Yeah, screwy sums it up nicely. Keep plugging at it. You may also want 
to continue to do web searches on resolution with other means, and 
possibly confirm which group associations your user needs to be a member

Dare I ask if you considered or actually rebooted after installation? 
While an obnoxious step most of the time, this is hook related and the 
kernel may not respond well (in rare instances) when packages are added.

You'll probably have to reboot to clear the lsusb issue if you can't 
find which process is keeping it bound up.

I'm going to guess it's systemd that's the issue, but that's just 
pointing a finger at something that I'm not fond of. If it's like my 
laptop, I suspect it's one of the network interfaces that are waiting 
for something to complete. (My system can take anywhere from 1:15-1:40 
to complete and move on.)

If I recall correctly, with CentOS there is a function key that can be 
pressed on the install disc that allows you to get "verbose" mode which 
just shows the old school "$process [OK|FAIL]" stuff. There may be the 
same option for Fedora.

Based on my terribly quick search of information last night, I believe 
the amd64 ISO for 5.9 is this link:



Other releases have the same filename, just under a different subdir. 
For example, the i386 ISO is here:

Unfortunately, I have no (or at least not recent) experience with 
installation of OpenBSD.

Have you consulted the README and INSTALL.amd64 files? (No snarkiness 
intended here.)




It appears there are some "gotcha" issues with this release per the 
README, and the second file gives you the information to use 
install59.iso to create the necessary bootable media.

I don't recall the exact cli command using dd to create the CD, or I'd 
pass that on here. If you have other software burning software, you can

You probably would benefit from the --delete flag. From the man page, 
this flag will "delete extraneous files from dest dirs" which I believe 
is what you want to accomplish.

Once you start getting more complex commands, it's sometimes better to 
move them out of cron directly. I would suggest that you build a shell 
script that works as you wish, then put that into place in cron.

Something like this should work for you:


  0 3 * * * /bin/bash /home/jjj/bin/mail-sync.sh

You'll have to adjust names and pathing accordingly.

In the script, you can have variables, comments, and other "gee whiz" 
kind of stuff.

If the cp command is giving you grief (a quick read of the man page 
suggests -u might be a possible culprit), and if you know how to use 
rsync, you might just switch to that and move on with your day.

Based on the command provided above, your execution line might even be 
as simple as this:

  rsync -a /home/jjj/Mail /media/jjj/Data/Mail

Of course, I don't have access to your system to verify that this would 
be proper syntax, but it won't be far from it. Additionally, in your 
script, you can create modifications such as multiple iterations of the 
backup, change names, and more, which would allow you to roll back 
farther than just one day if needed.

If you need/want help with writing something like that, I might be able 
to spend a few minutes chatting with you and/or providing a rudimentary 
script.

Well, quite honestly it was a long shot at best (IMO) and I didn't have 
a lot of faith in it, but something to try. It's still worth using the 
find to see what returns:

$ find /media/jjj/$WHATEVER -name "8½ 1963" -ls

This is just a sample that may return something, and then again it may 
not. There are a lot of options with this command, this is just a simple 
test.

That is consistent with a file or directory by that exact name existing 
already and the system won't let you execute the mkdir as a result.

Having no experience with Catfish, I can't help you here. Perhaps the 
filesystem has a phantom memory of a file or directory with the exact 
name you are trying to create. To clear this, try to umount the 
partition and run fsck on it. If that isn't possible, you may also 
consider a 'find' on the directory with the _exact_ name as the target.

If your tools suit your needs, please continue to use them. You appear 
to be a power user and I have more of an operations background where 
scripts that call lists and use variables for operations, the spaces are 
more difficult to escape or predict in behavior. I'm naturally 
pointy-clicky averse, so my experience is different than yours.

In my experience, any character that requires multiple keystrokes are 
equally avoided for the above reasons. There is nothing wrong with them, 
but they may break other things in odd ways down the road. I can only 
hope this is NOT the case for you.

Yes, the inode table seems to think the name is in use in that 
directory. See my above remarks about fsck and find.

Good luck.

Spaces work fine if you escape them, but when it comes to scripting 
things to manipulate files and such and working from the command line, 
it makes escaping the space very, very challenging if not impossible. As 
such, the use of a space (and special characters such as the funky 1/2 
being used) is generally *highly* discouraged.

If you are willing to use these characters you welcome to do so, but 
please don't complain when those characters break things for you in the 
future.

The only thing you can do at this point is to contact Comcast, but they 
will probably tell you what I've heard before: they only guarantee the 
upload speeds to the edge of their network.

If you run the speed test using the Comcast tool pointing to an internal 
Comcast server and still don't get what you are paying for, then you 
have a very valid complaint and they need to fix it.

What you get after exiting the Comcast network will vary, and based on 
your numbers, may indicate a Comcast cap in place for some reason.

I think that would work best.  The logic could look like:

if [ mailfile ]; then
  while [ addresses ]; do
send mail to top addresslist
remove top addresslist
  done 
  remove mail
fi

Then it's just a matter of cp'ing the mail and address files into place
one time. Unless you have the complication of trying to send a second
mail while the first is still in process.

The device /dev/sr0 is typically the first CD/DVD device found by the 
operating system (and /dev/sr1 would be the second). All it's saying 
(loosely) is that the device wasn't cleanly closed before eject and an 
inode is still being "accessed" even if no available any longer by some 
process.

This is why you can't mount anything new at this point with the device 
still being "busy", according to the kernel.

It also looks like the error is saying that /media/jjj is read-only at 
this point, and unless I'm reading the mount output from the previous 
email correctly, this would be /dev/sdb1. If this is the case, there may 
be errors on that partition and the filesystem was remounted read only.

What happens if you manually execute "mkdir /media/jjj/test" or "mkdir 
/tmp/test"?

The only way that I know to clear a read only filesystem is to remount 
it (if permitted), or to reboot with a manual fsck on the problem partition.

Just a cautionary note -- my spouse and I had basic no-contract Motorola
flip-phones until quite recently. However we have heard (and have
anecdotal data to back it up) that the no-contract phones tend to have

Re: [PLUG] Home Router Recommendations

Last time I had to make this decision I ended up taking the easy way out
and going with the top recommended option on wirecutter:
http://thewirecutter.com/reviews/best-wi-fi-router/ I've been pretty happy
with the device and haven't had to muck with it much. It does require a
restart to make static dhcp leases which is completely dumb but it's also
the only thing i've found that's out of line so far.


Prior I explored using a routerboard for this at home but found it was
limited in it's support for UPNP and DLNA. I also had good luck repurposing
a checkpoint vpn device as a pfsense box. It was just intel hardware which
made it easy to install pfsense on. Thats probably not a common thing for
someone to come across though.

Re: [PLUG] The Right Tool For the Job

[David Gibbons]

Adding the variable to environments without determining that is the
environment the code is running in is rather bad form.

You'd do better to write a separate script to print out the running
environment and evaluate if it sees it.

That actually tells you something about your environment and doesn't
pollute a namespace without cause.

 Rich,

 When I expect a variable to be in the environment and it isn't, I
 usually find that the application has shelled out of my environment and

Rather than creating a temp file, you can also subshell out and cat the
current contents, this executes before the command that wraps it so you
don't worry about clobbering the contents before reading them.

for filename in /path/to/app/source/*py

do if ! grep wxversion $filename

then echo import wxversion
wxversion.select('3.0.2.0')
import os, time, wx

$(cat $filename)  $filename

 Awk is for modifying existing data. You are adding completely new lines, so

Re: [PLUG] Installing to new disk

[David Gibbons]

  Second question:
  My desktop computer has an internal SATA drive and a SATA drive dock.
 The
  dock is normally used to hold my backup drive.  Can I do the install in
 the
  dock, copy data from the old drive to the new drive, then move  the new
  drive to the internal location?  Will the drive then be known as
  /dev/sdb1?  How do I tell the install program to find the external drive?

 When Linux boots, all drives get a /dev/sdX label but unless the
 partitions are in /etc/fstab they will not be automatically mounted.
 you can look in /var/log/[dmesg | messages | syslog]

 Find out all the /dev/sdXn as listed in the logs and then either make an
 entry in /etc/fstab (with out without noauto

 Also, once partitioned and formatted formatted, and depending on your
 WM/DE setting for dbus/udev, the hard drive in the dock should hot
 plug/automount.



You could also create a filesystem label instead of relying on what device
name the drives get. This way you can be consistent no matter if they get
reassigned.


This depends on the filesystem for which command you would use to label it
but for example with xfs:
xfs_admin -L MYDATA /dev/sdb

then in fstab
LABEL=MYDATA /mnt/data xfs ... defaults 1 1

Test this with the mount command with the disk unmounted and you can test
that it works as you want it.

googling for using labels in fstab comes up with more directions if
needed.
