Re: [PLUG] question on Mozilla Firefox holding up Yast2 system admin program

[Tom]

If I understand you correctly, you have done following:
1. Opened gnome terminal
2. Started Firefox by typing: firefox
3. You tried to start yast2 from the same terminal by typing: yast2
And nothing happened - Am I right?
If yes, then try to start firefox and yast2 as background processes by
adding & to the end of your command lines - like this:
firefox &
yast2 &
That way the commands will not block your terminal from executing
further commands.
Does that help?

Re: [PLUG] Running a Python application in the background

[Thomas Groman]

If your going to learn a new terminal multiplexer; make it TMUX. TMUX is
like screen but is a little more featured, less conflicting key
sequences, multi-user support, and more actively developed.

following command will recursively copy the content of the iso file

command is an alternative to cp which works incrementally and/or if you

Re: [PLUG] Running a Python application in the background

[Tom]

I'd second the use of screen as that will allow you to reconnect with
the shell where you started the command should you need it.
Another alternative to nohup I often use: at -f commandToRun now
The dependency is to start atd.service
The advantages to nohup that is that you will get the command's output
by email, so that you can check the success/failure and what happened.
Another good thing is that you can start your command with delay or at
certain time/date if needed.

Take a look at nohup (man nohup).

Traditionally this was done using nohup, but screen is probably a better
choice.

[PLUG] Running a Python application in the background

[Rich Shepard]

   A hydrologic model I need to run has an estimated completion time almost 4
days in the future so I start it in the background by appending '&' to the
command line.

   The problem is when I log out of the system and log in as root that
process (actually, there are 3 processes running, one with status Rl the
others as S (suspended).

   Is there an alternative way to have a program keep running after the user
invoking it logs off?

Is that a promotional price? If so, what's the term and what's the normal

Alea jacta est. Today I went to the 'store' in Hollywood and signed up.
(It's not a store, there's no merchandise for sale there, but I didn't
argue with them.) The 1 GB service is $70 a month, plus 3.99 for a
'recovery fee,' whatever that is, and installation is free. And I opted
to lease the modem for the time being, so the total comes to $83.97,
less $9.99 after I get my own modem. Installation is Tuesday 2/28.

Can't wait to tell Comcast to go suck eggs.

I think you're still in "too terse" territory. We are not familiar with any
way for Firefox to "block" any other application from opening. What do you
actually see when you try to open Yast2 while Firefox is already running?

And also, please confirm that opening Yast2 in this way does work when
Firefox is not running.

sorry about being too terse.

I was starting Yast2 from the command line, in one gnome terminal 
window, but I had another firefox window open already.

I was totally surprised, when firefox blocked the CLI command from 
executing.

Yes, but perhaps not in expected ways ;/
For example, I could read and but not really grok your code example. It 
prompted me to spend a productive hour in man pages. That may lead to a 
solution for some problems totally unrelated to this thread.

http://www.syslinux.org/wiki/index.php?title=Install#ISOLINUX ties 
together this thread with some problems/symptoms with attempting to use 
debootstap for "my goals" 
(https://lists.debian.org/debian-user/2017/02/msg00871.html).

You mount .iso through loop device and copy/rsync the content. Here is
and example:
sudo mount -o loop fileName.iso /mnt
cp -pr /mnt/* destinationDir/
# or: rsync -a --progress /mnt/* destinationDir/
sudo umount /mnt
If you want to make this bootable, copy the content to empty disk
partition, make it bootable by grub2.
Ubuntu CDs/DVDs typically use combination of Syslinux and Grub2
selected by BIOS/UEFI respectively to boot from the media:
