Subject: shell command to replace string in text files ?
Date: Sat, 31 Jul 1999 15:24:51 GMT
Hi all,
I was wondering if there is a possibility to search a list of textfiles
(for example all *.c in the current directory) for a string (for example
"myvariable") and to replace this string with another (for example
"mynewvariable") from the shell prompt. I don't want to use a text
editor, because this would mean that I had to open each file. There must
be something like "grep and replace".
Thanks
Stefan

Easy newbie question...
I'd like to copy (recursively) files and directories from my laptop to my desktop for
backup purposes. It seems there should be an easier way to do it than to fire up ftp,
login to the desktop, and do a put.

Most well-thought-out configurations don't include ./ in their paths
these days for exactly this reason. Yeah, it means that newbies occasionally
get confused as to why the shell can't find their program/script, but,
it saves an awful lot of wierd hassles in the long run.

Yes, but you offer *no* evidence that the scale on which it is happening is
large enough to damage those economies. In fact it could even help them, by
offloading the grunt work overseas, and creating more skilled jobs at home.

Ah, yes. "proof by anecdote". Try again, and provide some concrete evidence

Yes, but you've only offered a theory.
And the theory seems to be quite a shaky one. For example, the cost of labour
in the USA is extremely high ( much higher than anywhere in Asia besides
Japan and Singapore ). So why isn't the US's economy dying ? You provide
theories, but no evidence that the economy has been hurt.
Most importantly, the only examples you give are those of cheap labour being
moved off shore, while the professional jobs stay inside the US.

Hi, I just installed Suse 6.1 and it runs fine. I've spent some time
playing around with it and a few questions. By the way I am using KDE
desktop.
1. Is there any way of configuring Linux to automatically mount the
cdrom when you insert a cd into the drive and unmount it when I remove
the cdrom? I noticed that if I mount the cdrom manually I can't open the
drive door until I unmount it again. Is there anyway to automate this?
2. I am trying to upgrade from Netscape 4.51 to 4.6 but when I try to
run the install file I get a message saying "Can only start executables
on local drive"? I've tried placing the installtion files in various
places and try to run the install file but still get the same message.
This happens whether I am logged in as root or as a normal user.
3. With Netscape 4.51, I am not getting any colour icons / symbols -
everything is grey on netscape. Is this normal or is there a setting I
can change. I don't have colour problems with the rest of my desktop or
other applications.
Any help would be much appreciated.
Thanks in advance.

I hear that the problem is that they have to go thru the source code and
make sure they aren't using patented algorithms in it that they don't own
but for which they have a license for their own use.
In other words, if it contains technology owned by others then they have
to rework those sections before they can release it.
I also hear that working thru these intellectual property rights issues
is going to take awhile.

Reply-To: [EMAIL PROTECTED]

Part of this question I posted earlier but got no response.
I'm concerned that permissions are not working as I think
they should.
An ordinary user should not be able to kill a process owned by
root, right? But I've got a ppp dialup script which I can
run as an ordinary user, (because pppd is SUID, root-owned).
When the pppd runs, it is a process "owned by root". Yet,
as an ordinary user I can kill it with "killall pppd". Why?
On the other hand, root should be able to bypass user permissions
and read or write to files owned by others, right? But if I
mount a msdos filesystem with the UID=501 option, so that user 501
can read/write to it, root gets "permission denied" when trying to
write to that file system. Why?

You may be right. It's not like they have an "Oracle for Dummies" book, or
books for other back-room programs (or do they?). But you'd be surprised on
how few books they actually have to sell to break even, then only a few more
to make a profit. I think what's driving "Dummies" to print a book on Linux
is the misguided public thinking that Linux is a good replacement for Win95.
Now before you all get your tails all bunched up over what I just said, read
on. In my travels in the field delivery arena I have found some serious
DEUs thinking that they should grab Linux and install it on their laptops.
They don't even know how to backup their current user files, much less how
to install an OS. I don't doubt that most of these people, if they were to
install Linux, would do so over all of their existing files and then get all
pissed off when they realized that the installation procedure formatted
their disk under ext2 and erased all of their old stuff. No matter how easy
you think a RedHat or Caldera install is, the standard end user WOULD find a
way to foul it up.
Maybe the "Dummies" books are good for that. But don't you think that
they'll have to write one "Dummies" book for each distribution? I mean,
when you're talking about DEUs, you have to know that they follow directions
screen-by-screen. They have no idea what to do when the setup utility asks
them which "Daemons to start at boot". So you'll have to have one book for
each dist, with screen-by-screen explinations, blah, blah.
I think Linux is a powerful operating system and the 4 machines that I have
running it right now are doing so without any problems. But I am extremely
skeptical about the usefullness of Linux on the DEU's desktop.
If there are new reasons why my fears should be lessened, please explain.
After all, that's what Usenet's all about, right?

Subject: gbeta-0.8 available (An advanced OO pgm. language, GPL)
Date: 31 Jul 1999 08:18:23 -0700
We are pleased to announce that
gbeta-0.8
---------
is now available.
What Is It?
===========
gbeta is an advanced OO language which supports virtual
attributes, general block structure, and dynamic inheritance in
context of strict, static typing. It is a generalization of the
language BETA. The package includes an implementation of the
language which performs static analysis, generates byte code, and runs
the given program (i.e. it works like an interpreter as seen from the
outside). It is integrated with GNU Emacs and programs can be single
stepped, declarations can be looked up by double-clicking etc. in this
environment.
The current version of gbeta comes without standard libraries, and the
performance is not good, so it is relevant to use it if you want to
play around with a bleeding edge OO programming language in order to
see what possibilities it offers you as a programmer, but it is not
yet ready for real-life application development.
Platforms
=========
gbeta is available for Linux and SunOS 5.6 / Solaris 2.6 (it runs
under SunOS 5.7 / Solaris 7, but must be compiled under 5.6). More
platforms will be added soon (see the website).
Documentation
=============
The gbeta web site at
<URL:http://www.daimi.au.dk/~eernst/gbeta/>
contains information about installation, getting started, a tutorial,
references to papers, and several other topics. My PhD thesis (which
is mainly about gbeta) will be made available from this web site, too.
Download
========
gbeta can be downloaded from the above mentioned web site at
<URL:http://www.daimi.au.dk/~eernst/gbeta/index_download.html>
or by ftp at
<URL:ftp://ftp.daimi.au.dk/pub/empl/eernst/gbeta-0.8>

Really? Oh, maybe you mean doing a put for each individual file? That

man ftp, look at the mput command. You can do wildcard expansion

It appears you have a number of problems here.
First of all, see if all of your packages are good rpm's:
rpm -K --nopgp *.rpm
You should get something like this:
$ rpm -K --nopgp *.rpm
ORBit-0.4.3-3.i386.rpm: size md5 OK
audiofile-0.1.6-5.i386.rpm: size md5 OK
control-center-1.0.5-22.i386.rpm: size md5 OK

gdm-1.0.0-36.i386.rpm: size md5 OK
gedit-0.5.4-1.i386.rpm: size md5 OK

gnome-utils-1.0.1-6.i386.rpm: size md5 OK
gnorpm-0.8-5.i386.rpm: size md5 OK
gnotepad+-1.1.4-1.i386.rpm: size md5 OK
gnumeric-0.27-1.i386.rpm: size md5 OK
gqview-0.7.0-1.i386.rpm: size md5 OK
imlib-cfgeditor-1.9.5-5.i386.rpm: size md5 OK
libgtop-1.0.1-3.i386.rpm: size md5 OK
libgtop-examples-1.0.1-3.i386.rpm: size md5 OK
mc-4.5.36-2.i386.rpm: size md5 OK
Download again any rpm's which are not 'OK'.
Next, see what the problems are going to be:
rpm -Uvh --test *.rpm
This doesn't actually install, it just kicks out
dependency violations.
When you install the rpm's you should be the root user.
If you are installing a newer rpm which just happens
to have the same number as an existing rpm, try this:
rpm -Uvh --oldpackage --force blahblah-0.1-1.i386.rpm
If you have failed dependencies you will have to obtain
the rpm's with the needed files and install them.
Best of luck...

Subject: Re: How to avoid needing an fsck (was: Linux crashed)
Date: Sat, 31 Jul 1999 09:56:56 -0700
David,
Is there any way to configure Linux so that it does all directory update
writes immediately but caches regular file writes? What I'd really like
is to be assured that the directory structure doesn't get corrupted. At
least that way the files will all be accessible even if some of them
didn't finish getting written before a crash.
Also, why is this work-around below necessary? If Linux is flushing its
disk cache every few seconds shouldn't it be enough to just wait 30
seconds before hitting reset?
Seems to me what is needed when the UI is hung is to have a way to stop
all processes that are doing writes, wait for the file cache to flush to
disk, and then shut down.

Check that you've compiled APM power-off support into the kernel.

Modern PCs are WinComputers to mainframers. :) (Like WinModems....)

I once worked on a puny HP3000 of late 80's vintage. This machine had
60 people hanging off it in the morning, while processing dozens of
database requests. Response time for editing was excellent, however.
Mostly due to the fact that the hardware had (and used) blocking IO for
the terminals.
In comparison, a much more powerful similar vintage VAX with polling IO
would be unusable for editing with just 30 people logged on. DECserver
terminal controllers were the order of the day for that installation.
Much more efficient.
Is anybody up for designing FreeMVS? It seems a real pity to let the
era of mainframe machines slip away to big backroom servers that only
grizzled COBOL programmers get to use.... ;)

I'm 50. I have a degree in Engineering Mechanics. We had an IBM Mainframe
when I was in college, with a whopping 500K of core. I wrote 2 programs in
FORTRAN during college. Both were less than 600 lines. I engineered for a
while designing industrial equipment. Then got hooked on an Apple II+.
Haven't been the same since according to my wife.
I now work with IT for a living. I use Linux at work and at home - by
preference. Linux has put the fun back into computing for me. I also have
an NT desktop (I have two desktops at work, Linux gets the better one)
relegated to Lotus Notes and an occasional "can't be avoided Windows
programming".
My wife uses Linux at home (on her machine). My son - who is going into
Hotel and Restaurant Management - uses Linux by preference on both his
desktop and laptop. He's a smart lad, but he's not a computer geek.
I was a part of the beta program testing Win95. I really liked it, it sure
beat Win3.1 back then). Then I started getting irritated by crashes. The
straw that broke the camel's back was *having to* upgrade a perfectly good
VB3.0 program to VB5.0 for Y2K compliance (for my wife). I couldn't do it.
There was no translation for the old VBX's. I'm now doing it in perlTk in
Linux.
I haven't paid a dime to Microsoft in well over a year. And I don't plan
to in the future. I also recommend against Microsoft at work...
