Exit from su in a script

yc_2 — Tue, 03 Oct 2000 02:32:11 GMT

Hi,

In a script, how do I exit from:

su - user -c "command"

and continue other operations within the script.

Thanks in advance,
YC

Unfortunately I don't have a system at hand to test this. Can you place the command in the background in the script?:

su - user -c "command" 2>&1 &

Cheers,

Murray

Hi Murray,

The subsequent operations has to be done after the completion of the "su" command. How to go about it with your suggestion ?

Rgds,
YC

when you do su with -c "command" option, the su will exit as soon as the command finishes its job. put your additional command next to it and things should work.

I have a script which start the oracle listener demon and then start the oracle database in the same script
su - oracle -c 'lsnrctl start listener'
su - oracle -c '/oravl01/oracle/dba/util/start_ctx.sh'
su - oracle -c '/oravl01/oracle/8.0.5/ows/3.0/bin/owsctl start wrb'
. ~oracle/.profile
/oravl01/oracle/8.0.5/ows/3.0/bin/owsctl start www
su - taskman -c '/opt/OV/taskman/bin/ptm start DEV'

hope this answers your question

Hi:

When you complete the command or script specified with the -c option, you will be returned to the script and environment from which you came. No special action is necessary.

When the command specified runs and terminates, it goes to the next line in yur script. It does not need an exit sentence to terminate its process of execution.

Try this :

su - user -c "command" 2>&1 &

wait # wait all backgrownd commands

#next command
