General :: Check If Process Is Running / If Not / Execute Another Script
Jul 11, 2011
I have a game server running using java, and it tends to crash sometimes, and only way to start it now is manually, so i thought i could create a script to check periodically if java is running, and if it isn't, run my startup script for the game server also, if it's possible it should log when it actually started the server startup script into a text file or something, so i can check why it crashed.

I have a computation going which takes a long, but uncertain, amount of time. I have another computation which needs to be run, but _after_ the first one is done. I won't be at the computer at that time to manually start the new process. I've done some Googling, and I found how to delay execution by a specific amount of time (e.g. "start process x in exactly 8 minutes from now), but that isn't quite what I want to do. Essentially, I'd like to tell the shell, "When process #nnnn finishes running, then start process x". Is there a way to do this?

When running the script i get the following error message:
syntax error near unexpected token `else'
Here is my script.

I have an Ubuntu server in which a file is dumped every hour and a new file for the next hour and the process continues. If there is any problem due to which the creation of file stops then empty files are created every minute till the process is killed & started again. I need help to make a shell script to check if the empty files are being created and then kill the process and start it again.It would be a great help if anyone can help me regarding this.

I run a script manually like/usr/lib/openoffice.org/program/soffice and when I run
:ps -ef|grep openoffice
I get the following,
root 700 1 0 10:45 ? 00:00:00 /bin/sh /usr/lib/openoffice.org/program/soffice -calc
My question is how to check whether this script is running or not (It can be checked every 10 minutes) and how to make it as a service. (I don't have root access to put this in rc.local file or somewhere else).

How do i check if NFS mounts are still up and running?
when i do the command MOUNT , i get some result, but how can i see (or check) if they still up and running? I'm not so familiar with this command, so i hope that someone can guide me
I know that there must be some NFS links mounted, so if one fails, i need to see that with like an echo or something.

so I wrote a small script that pretty much just takes in two numbers and counts from the first to the second, e.g.
unknown-hacker|544> count.sh 1 3
1
2
3
My problem is I want to make it so that if you input invalid parameters, such as non-numerical characters, more than 2 numbers, etc., you'd get an error message

I have a bash script that messages the user periodically. Is there any way in the script to check if the screensaver is running, so the script doesn't spam messages while the user is away? The xscreensaver process is always running in the background, I've noticed.

Is it possible, using ps, to determine where a process is running from? I have two applications, both are identical and running in parallel directories, such as /app1/start.sh and /app2/start.sh. If I run ps -ef then I'm unable to tell the difference between the two
Using ps (or alternative), how can I tell that PID 123 belongs to app1?
