set a name to sleep process in shell
I'm a newbie to linux and has a task of writing a script to automate some work
Currently I have a script (runme.csh) with content like this
#!/bin/csh -f
read some settings from a file>
while (some condition)
< do some work >
sleep 600
end
Now I need to run copies of the script multiple times (copy the script to new file name and run) on same shell [tcsh]
example
[aruna>] runme1.csh &
[aruna>] runme2.csh &
[aruna>] runme3.csh &
Now if I wanted to kill one run I can do ps, find the PID of respective script by its name and kill. However I have no way to find the pid of the sleep command that script executed.
Is there a way to give a name to the sleep process so that I can see which sleep process is executed by which script?
Thank you :)

It seems that you can't properly do that using bash alone, as exec -a foo sleep 100 still shows up as sleep when using ps:
[~ ]$ ps -u corion
PID TTY TIME CMD
...
101468 pts/8 00:00:00 bash
101494 pts/8 00:00:00 sleep
But using Perl, you can easily change the name of the process because Perl supports
assignment to $0 (the name of the process, in Perl):
perl -wle '$0=shift;sleep shift' sleeper 100
[~ ]$ ps -u corion
PID TTY TIME CMD
...
100740 pts/8 00:00:00 bash
104067 pts/8 00:00:00 sleeper
The above oneliner changes the name to the first argument given and then sleeps as many seconds as the second argument given.

Hi Corion,Thanks for your valuable input. But it didn't work. I can see "perl" as the process, not "sleeper"

@arunarubashinghe: Oh, that's bad - on RHEL6 (with whatever kernel) that worked, and on a Debian 9.5 3.16.43-2+deb8u2 kernel, it also works.

It seems that you can't properly do that using bash alone, as exec -a foo sleep 100 still shows up as sleep when using ps:
[~ ]$ ps -u corion
PID TTY TIME CMD
...
101468 pts/8 00:00:00 bash
101494 pts/8 00:00:00 sleep
But using Perl, you can easily change the name of the process because Perl supports
assignment to $0 (the name of the process, in Perl):
perl -wle '$0=shift;sleep shift' sleeper 100
[~ ]$ ps -u corion
PID TTY TIME CMD
...
100740 pts/8 00:00:00 bash
104067 pts/8 00:00:00 sleeper
