I'm trying to execute some code (let's call it login.java) when I log in and out of my linux machine. Is there any way to do this? I'm looking for perhaps a way to trigger the code? I've thought of just putting it in my .bash_login but preferably the code would launch on normal login, not when I start my terminal.

After connecting the external monitor, I found that this one shows good graphical start-up but just upto the login screen(just before the login screen, login-screen does not come) and it proceeds no more.Though I can get the virtual consoles restarting xserver is of no use.

View 2 Replies View RelatedI am using CentOS 5.4. I created a bash script that does some checking before running any commands. If the check fails, it will simply exit 0. The problem I am having is that on our server, the script will exit the su or ssh session when the exit 0 is called.
#!/bin/bash
# check if directory has contents and exit if none
if [ -z "`ls /ebs_raid/import/*.txt 2>/dev/null`" ]; then
echo "ok"
exit 0
fi
Here is the output:
[root@ip-10-251-86-31 ebs_raid]# . test.sh
ok
[russ@ip-10-251-86-31 ebs_raid]$
I was removed from my sudo session, if I wasn't in the sudo session, it would have logged me out of my ssh session. I am not sure what I am doing wrong here or where to start.
I have 3 script BASH. I want start this script when the system start,stop and reeboot.

This is the deal. I installed kubuntu yesterday. Now when it prompts the start session screen, I write the user and password, click enter and then starts loading a new screen. It shows an hdd draw, and starts loading some other images, and all of a sudden it prompts me again at the start session screen.

View 3 Replies View RelatedThe problem is this: My movie collection is growing that large that it no longer fits on the 3TB storage I have available for it in my server.therefore want to start using external disks, but as I don't want to waste electricty I want to switch this drive on only when I want to watch a movie which is on this drive. This drive will be connected to my server running Fedora 15 x64. The movies will (most likely) be played by a machine running XBMC on an Ubuntu minimal install (10.04). Currently I use NFS to create a mount on this machine to my media folder.The question: How can I best setup this external drive and shares etc so to have these movies available from my XBMC machine when I switch on the drive, but nothing crashing when the drive is off (while the XBMC machine stays on)?
View 8 Replies View RelatedI am using Fedora and trying to auto run a script soon after the unit boots to desktop. I found many suggestions and finally decided to use the Sessions->Startup Programs option (under System->Preferences->Personal->Sessions menu). I added my script in the Startup Programs with the command 'sh myscript.sh'. Now I have two questions here:1. When I use the command 'gnome-terminal -e myscript.sh', I get 'There was an error creating the child process for this terminal' message after logging into the desktop. Can any one tell if I am missing something here?2. Even if I use sh instead of gnome-terminal, I still want to see the script executing. In other words, my script has certain echo statements indicating the flow of the script. But I don't see any shell opening up with these echo statements showing up, after the unit boots to desktop. But the script was still executed with no problem

I've been switched to a new department at work and am totally clueless when it comes to scripting in bash. When I told them I was a fast learner, I didn't think they'd throw me into the deep end of the pool so fast. So to make a long story short. What is a great book to start learning scripting in bash? My supervisor already gave me a simple task to do. Conceptually it sounds quite easy in my head, but actually writing out a script is a bit more daunting and complexed than I first thought.

View 9 Replies View RelatedAwhile back, PabloTwo pointed me to zenity as a way to create bash scripts with changeable parameters. That thread is here, for anyone interested in reading about it: [URL] Anyway, my problem is that I'm trying to capture input that contains double-dashes ("--") but zenity (or maybe or it's bash???) complains with the following error message:
"This option is not available. for all possible usages.
bash: [/code]: No such file or directory"
Here's an example of what I'm doing:
Code:
# Select the time of day
Flytime=`zenity --list --text="Select the Time" --radiolist --height=300 --width=300 --hide-column=2 --column="Select" --column="Code" --column="Time of Day"
"" "--timeofday=real" "Local Time"
[code]....
What I want to accomplish is for the variable $Flytime to contain either "--timeofday=real" or "--timeofday=dawn" (without the quotes) depending upon which radio button is selected. I have tried escaping "--timeofday" (e.g. "--timeofday" and even "--timeofday") but that's not working.
I need to code a media streamer in java but I found out that I would need the java media framework to simplify the task. I downloaded the bin and need to export it into the files where my jdk packages are at by default. I'd rather not set my path variables because I'm not so good at interfacing with BASH. I just want to start nautilus in sudo and drag and drop like I did with my python packages. I am just having trouble locating the jdk lib.I'm not using openjdk but sun-jdk 1.6.18. My OS is Lucid. The package is JMF2.1.1e. I'm pretty sure I just need the just the lib files from it and none of the executable.

View 2 Replies View RelatedMy question has to do with how environmental variables are passed from parent to child processes at the BASH SOURCE CODE level. I have a need to add an environmental variable that has the complete invocation line so that the child process can see it via ENVP.I have been studying the source for a quite a while and can't seem to find how to make the variable pass to the child. In EXECUTE_CMD.c I found a good place to set the variable: I made a routine similar to PUT_COMMAND_NAME_INTO_ENV called PUT_COMMAND_LINE_INTO_ENV which would add "?=THE FULL INVOCATION LINE" as an environmental variable but it doesn't make it to the child. (I've tried names other than '?' but they don't work either.
I'm thinking that there is either a LIST or a attribute associated with those environmental variables that should be passed to the child but I can't find it.

Gnome sessions started hanging during login on a debian lenny box, and I can only think it's related to a recent package update as it was working fine before the last set.
