but the execution of this script is through oracles scheduler
so i want to find out as what os user is the script been run

how can i do this
or is there a way to capture the user that is runnig the script in a variable a put it into a file

The script is probably being run as the user that executes the oracle scheduler ( user oracle maybe? )

In the script you can do things like echo `id` >> /tmp/id_of_user

As well as echo $$ >> /tmp/process_id

Or something like that to get the info you need.

the script is supposed to run as nobody the lowest privileged user
but how can i find out if or not the script was run as nobody
or some other user which depends on the owner of the extjob in oracle bin folder. i just need to find this out which user is running the script at os level

You can tell the script to run 'whoami':

Code:

itsme@dreams:~/scripts$ cat who.sh
#!/bin/sh

whoami
itsme@dreams:~/scripts$ ./who.sh
itsme
itsme@dreams:~/scripts$

I've already given you the answer to how to run it, itsme86 is just telling you how to do it in a different way.

hi,
"ps -axl" will give the PID and the UID.
