Team,

I have a shell script which will b run in cron job. On an adhoc basis.
The script needs to be run such that the moment it goes to the particular directory.
It should adapt to its ownership. But the script which i had shared below is run by a single user having admin privilege.. would it be possible for you to share with me such that it uses it own file ownership ?...

File ownership of the particular directory as below:
1)Trigger/archive directory:is owned by PSAPWCC user
2)XS-SuperSwitch/archive:is owned PSAPADM user
3)logs/archive:is owned PSAPROA user

Script details as below:

Name of the script:SCANIT_File-System_Tidy.sh

# This script will be used to delete the data which is older than 60days
# from Archive folders Trigger/archive, XS-SuperSwitch/archive, logs/archive

Didn't really understand what the problem is?
- Is it so that you copy and paste this script in 3 different directories (say x and y) and then when you run x/script.sh it must be run as user "x" and when you run y/script.sh it must be run as user "y"?
- Which shell are you using?
- Is there a problem with whoami ? Have you checked man id ?
- Post the error you're getting.
