Hi All, I want to redirect the username and the password as two inputs to a UNIX command from a file (the UNIX command prompts for username and password before proceeding). However, I cannot get it to work. The UNIX command still stops at the password prompt. The contents of the input file I used is like below: user1 passwd1 Any idea what the solution should be? Thanks in advance!

Under Unix/Linux, typically expect is used to handle interactive programs - especially using the passwd command. Check out this link: http://www.computing.net/answers/un...

Thank you, Nails! So automating the username/password is impossible from the shell.

Sorry, I didn't see this until just now. Without using something like expect, yes I'm afraid it is. However, since you are using Solaris, you might find this link interesting: http://www.unixreview.com/documents... This link includes a "C" program, setpass, which allows setting a user's password. You might find it useful.
