I have written a script which will run a script for a backup before:
# cat backup-before-shutdown #Scritp to take backup before shutdown #Author Ashish Karpe echo "Taking backup to s3" su ubuntu /bin/sh /home/ubuntu/backup.sh /bin/sh /home/ubuntu/backup-to-s3.sh
Normally when I switch the user from
ubuntu it doesn't ask password as its switching from
ubuntu but it's asking while running the script. So what should I do to avoid the password in my script?
