Shell Programming and Scripting

Hi There,

I'm trying to get a script to su to a user and then run a following script but all it seems to do is su to a new users within a new shell and then run the commands after in the old shell.

Is there a way to su and then get the user to run the commands?

Cheers
Kees

Instead of:

su [-] someuser
newscript.sh

use:

su [-] someuser -c newscript.sh

Whether you put a "-" between "sU" and "someuser" depends on whose environment you want to use when executing the script "newscript.sh".

If you use:
su - newuser -c newscript.sh
the environment settings of "newuser" will be used.

If you use:
su newuser -c newscript.sh
your own environment settings will be used.

Thanks, can I ask what the -c does?

passing a single command to the shell

Code:

man su

Here are my two scripts, I want the first one to change to eupuk and then run the second one, but it doesn't seem to work.

kees.sh
su - eupuk -c /backup/ops/HSBC_file_transfer.sh

HSBC_file_transfer.sh
#!/bin/ksh

#ln -s /cer_eupuk/exe/ABS_LOGICALS ABS_LOGICALS
#. /cerillion_homes/euphony/users/tes01/.profile
# User Variables
FILEPATH=/cer_testgmt/work/par/hoca
FILENAME=HSBC_LO*
FINANCESCRIPT=/cer_testgmt/exe/par60105b_auto.sh
cd $FILEPATH
cp HSBC* /cer_testgmt/work/par/hoca/tmp

if [ -f $FILENAME ]
then
$FINANCESCRIPT
fi

I Get the following when I run it.

Can anyone shed any light please??

It's clear to me, the o/p is already telling you... Two "errors":
- Permissions: The user has no righs to do that copy. Just chmod those files. Take into account that the user eupuk must have rights to do those cps.
- Environment: Oracle variables not set for the user. Just set them on HSBC_file_transfer.sh.

Regards.
Just read the messages.

I've sorted out the file permissions error, that was a mistake by me.

But with the oracle env settings, that user that i've su'd to has them already set, why is it not picking them up?
