How would I determine which script is being executed by a process? When I use:
ps -u user
I get the following output:
10005194 26932 0.0 0.0 112700 1544 ? Ss Jun03 0:00 -bash
10005194 27117 0.0 0.0 112700 1528 ? Ss Apr24 0:00 -bash
10005194 27164 0.0 0.0 112700 2040 ? Ss Jun06 0:00 -bash
10005194 27404 0.0 0.0 112700 1544 ? Ss May27 0:00 -bash
10005194 27484 0.0 0.0 112700 1528 ? Ss Apr23 0:00 -bash
10005194 27531 0.0 0.0 112700 1528 ? Ss May22 0:00 -bash
...
There are hundreds of lines. I know that there are a number of scripts that this user is executing, but I would like to narrow down which of the scripts is holding onto threads. Is there a way to do this?
Use the w (for "wide") option.
From man ps (search for wide):
wWide output. Use this option twice for unlimited width.
e.g. ps ww -u cas:
$ ps ww -U cas | grep bash
1350 pts/0 Ss 0:00 -bash
18345 pts/34 S 0:00 /bin/bash /home/cas/bin/myscript.sh
21293 pts/34 Ss+ 0:00 bash
The -bash is a login shell.
The plain bash is a non-login interactive shell - the tty pts/34 is the same so you can tell that it is the parent shell (or distant grand-parent) of the myscript.sh bash shell.
Using /usr/env/bin bash prevents you from determining which script is running. Instead you should specify exactly were the bash executable is for the machine you're running on.
