Shell Programming and Scripting

Dear all

I would like to capture who executed a script to a script's variable (i.e. testing.sh), so I can save it to a log file.

testing.sh
#! bin/ksh

user=`<< code here >>` // get the info below in RED color

<<main logic>>

echo "$user execute testing.sh on `date`" >> testing.log

--END of script--

Below is output of who command in my AIX UNIX server.
devlib pts/2 Jul 28 16:41 (pc001.testing.home)
devlib pts/3 Jul 28 10:48 (pc001.testing.home)
devlib pts/6 Jul 17 11:23 (pc002.testing.home)
lisadm pts/7 Jul 24 17:50 (pc008.testing.home)
devlib pts/8 Jul 07 11:51 (pc003.testing.home)
lisadm pts/9 Jul 25 09:45 (pc001.testing.home)
sccs pts/10 Jul 25 17:38 (pc002.testing.home)
devlib pts/12 Mar 05 17:59 (pc005.testing.home)
devlib pts/13 Jul 28 10:33 (pc008.testing.home)
devlib pts/14 Jul 17 11:23 (pc009.testing.home)

The first column is UNIX account ID, which is shared by a group of peoples. The last column is the computer name that open the terminal. How can I know (e.g. pts/3, pc001.testing.home) was executed the script?

Thank you very much.

ps command is your friend here.

Suppose I am running a script testing.sh ,you can find that out by the ps -ef command.

Code:

[root@iqmango ~]# ps -ef | grep testing.sh | grep -v $$
root      5413 12390  0 15:15 pts/2    00:00:00 sh testing.sh

Hope this helps!

It really help.

Thanks for your hints.
