Hi, Thanks a lot for your quick responses. After executing su - user2 -c script . I am asked for password for user2. Is there any way through we can we specify password too with this command. - Rajiv -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
As Mike suggests, you can use sudo. Then with the option -S to specify that the password will come from standard input instead of tty (and then feed it using the < redirect), and the -u user2 to specify to sudo to user2 instead of to root. The security vulnerability being that your password will have to come from somewhere (either within the script or redirected from within a text file containing the password) readable. Meaning someone who disects the script can figure out where to go find the password (if it's not in the script). There may be a way to do this a bit more securely, but I am not certain. I gather the script will run unattended, or will be run by someone who should not know the password for user2? If user1 is any bit curious, he/she will be able to find out the password for user2 quite easily by examing the script. Unfortunately the script won't run without r permission in addition to x permission (I tried with x but no r and the script will not run). Jacques B.
