Shell ksh

I cannot execute script in profile of a user. Script sybase.sh setting some variables.

Hi,

Put a "set +u" just before you call this script in your profile. "set -u" will print if there are any undeclared variables.

By default SHLIB_PATH is not set so if you run
SHLIB_PATH=/sybase/ASE-12_0/lib:/sybase/FTS-12_0/lib:/sybase/OCS-12_0/lib:$SHLIB_PATH
coz $SHLIB_PATH is not set it says...
Just remove the last entry $SHLIB_PATH and keep it

SHLIB_PATH=/sybase/ASE-12_0/lib:/sybase/FTS-12_0/lib:/sybase/OCS-12_0/lib
and see if it works

To fix your problem you have to source the script so it sets the variables in your current environment. If you simply call the script, it will set it for the child process and when the child exits, the variable definition is gone.

Instead of:

# ./sybase.sh

try:

# . ./sybase.sh <<< Note the dot space

Also the permissions on those files are not very secure. Once you reslve the issue, make sure you take the extra step to secure the permissions on all the files in the directory.

Hi,

Tim is right. I didn't try to download your profile as it is in zip format so I thought u had it correctly. If you are simply calling it like /home/sybase/sybase.sh, then those variables won't survive for the parent shell unless you source in the script as ". ./home/sybase/sybase.sh".

By the way you have to unset "set -u" too otherwise, it may throw errors.

A variable of scripts sybase.sh is defined:
SHLIB_PATH=/sybase/ASE-12_0/lib:/sybase/FTS-12_0/lib:/sybase/OCS-12_0/lib:$SHLIB
_PATH

I execute the command:
$ echo $SHLIB_PATH
/sybase/ASE-12_0/lib:/sybase/FTS-12_0/lib:/sybase/OCS-12_0/lib:

This good that obtains this result, Both points this good?

Hi Jose,

Put "set +u" at the beginning of your sybase.sh script. It inherits "set -u" from your .profile and throws out error.
