Is there any way to have x server on multiple shells at a time?(eg. Sally is logged in on shell 6 with her own desktop cube while Rob is logged in on shell 7 with his own desktop cube, etc)
View 2 RepliesI was able to set up SSH and log into my linux machine and I want to interact with shells already running on the desktop. I can locate and view the processes but I'm wondering if its possible to "get into" the program I already have running via SSH and enter commands.

View 1 Replies View RelatedIn a script I am writing I am trying to add logic so that the script can figure out if a remote server uses rpm or dpkg and then run the appropriate command to print a list of installed packages. This works locally, but I need to get it to work through SSH and I have no idea how to do that. The relevant portion of the script is below. It would also be nice to find a way to not need the full path to the executables but I'm not real concerned about that.So anyone know how to make this code work via SSH?

How to submit multiple jobs onto a Linux server. The only way I know to submit and run a job on a server is using qsub, and verifying the status of the job using qstat. I usually run my scripts using qsub -cwd so that I can run it on my own directory (instead of having the results sent to a scratch folder).
1. However, assuming qsub/msub are not available, is there another way to do it? What commands can I use instead?
2. I know that some jobs can run in the background, is that an alternative? How do I do it? And would I still be able to check the status of the job or delete it?
Well I am new to Linux. Do we have different media like CDs or DVDs for desktop and severs

View 4 Replies View RelatedSometimes I connect to my Debian box from another computer (using SSH on Cygwin or Linux), and once ina while I want to run some console apps. And sometimes some of these apps might complain about "another intance, Error: an instance of newsbeuter is already running (PID: 2496)". Is there a work around for this issue at all(without killing the original instance") ? The reason I do not want to kill the app because there might be 2 users connected to the same machine that might be using the same app.

If I do not do this, I will likely have to re-install the O.S numerous times due to changes in the database server o.s as well. The same question goes for the server; would it drastically effect the performance to install 3 server o.s on one server?
View 4 Replies View RelatedDespite the history file is unique (~/.bash_history) I see that the multiple bash processes run on different windows are not all updating that file. I presume that the bash is not taking into account this possibility (multiple bashes on multiple windows) and writes thus the history file in a simple straightforward way. This would mean that a number of history entries are lost. I've tried to find information but had no luck so far.

View 1 Replies View RelatedI am using Linux some years, but since I built a LFS, I feel noobish again. Now with the help of BLFS I am setting up my environment and somewhere I incidentally read, that not every variable is inherited by a child Bash shell. As for the $PS1 and $PS2 variables I know, that they are not inherited by non-interactive Bash shells (and there is no reason why they should in my opinion). Well, as for my first thread I hope the title gives enough information on what I want to know. But anyways: Which environment variables are not inherited by Bash shells?
View 1 Replies View RelatedFor example, if I'm in csh, I can use `setenv VARNAME varVALUE` while I can use export in Bash. Given that the environmental variables are created, can BASH read env vars from csh and vice versa?

View 9 Replies View RelatedI'm interested in testing Maverick, (or the next release, or the one after that) but always run into a problem with testing that runs alone the lines of.I have my current install (10.04) I have two partitions, / and /home, it works well.As soon as I add a new version it seems to be recommended NOT to have them both point to the same /home partition, the problem is, if I don't do that I don't have all my files, and it's a pain in the rear to setup.So what I was thinking is to have three basic partitions,
/
/home (for config files, and true HOME files)
/data (for all my actual data)
Create links from say /home/james/documents to link to /data/documents that way I can get to my documents.This way if I add a new version I can setup either the same (two partitions, / and /home and point /home/xyz/documents to /data/documents) or keep it slightly simpler for testing, just have one partition and repoint /home/xyz/documents to /data/documents.The main one I can think of would be permissions for files/folders?
I need to run two instances (i.e run the program twice, with two separate windows) of Audacious. This is for a play where I need to have music and sound effects going at the same time. I could do this while running Fedora 13, but after upgrading to 14 the audacious package was updated and now can't do this. My attempts at downgrading have been unsuccessful, and I need the audio done by tonight (the last rehearsal). So... am I up the river without a boat, or is there a fast solution? I'm open to anything, as long as the music player has advanced controls (play, pause, stop, fast forward, rewind, forwards track, backwards track) and can have two instances running at the same time.

View 2 Replies View RelatedI am trying to figure out where variables are set for interactive shells? In particular, I am trying to have LS_OPTIONS inherited by interactive shells as it is by login shells. I understand LS_OPTIONS is set in /etc/profile, and this may not be processed by interactive shells but by login shells. However, I also note other variables such as PATH and INPUTRC are set correctly in interactive shells, and these are also set in /etc/profile from what I understand. So how is it determined which variables are inherited by all shells, and which are just for login shells?
View 16 Replies View RelatedLet's say that I have a customized Bash prompt stored as a PS1 variable. My variable gets read every time I invoke a login shell, i.e., when logging in in one of the standard virtual terminal or by invoking xterm with the -ls parameter.
However, when I just invoke the terminal without specifying that it is a login shell, I just get something like: bash-XXX$ as a prompt.
where should I place my PS1 variable so that it could get read even on non-login shells?
