unset VAR

[unixkid]

Have some application scripts that appear to be hung up on VARS. Five scripts run and each set VARs but I would like to know if there is a command to unset all VARs before running thr next script (starting with a clean plate so to speak..) I'm running a ksh shell

If you run your scripts in separate shells, you should not have that problem.
Else, what you may do is set the variable but not export it.

 

[unixkid]

yes each VAR is set in diffrent scripts but it seems after the scripts have been run the previous VARs stay set

 

[lfoata]

Then it means you are exporting the VAR. If you do not want the VAR to stay in your environment, dont export VAR in your script.

Set the VAR at the beginning of each script.

You could use a wrapper with a set minimal of variables defined.

e.g

#!/bin/sh
./environment
# where environment is a list of VARS to be exported
./rest_of_script
# where rest_of_script is your original script with no environment or shell stuff in it what so ever.

Use this kind of thing a lot when using cron Ian
