I think you are asking how to update a user's unix password?? If so, as you know, it requires root user or root privileges. Second, the passwd command changes a users password. passwd is an interactive command. It works fine from the command line, but to use it in a shell script requires a method for sending input to passwd. Typically, expect is used. This link explains how to use and obtain expect: http://www.computing.net/answers/un...

what i want is to change the users password without knowing the old password. Fr ex , if the user forgot the password i want to create new password for that user.If the user name is like 'suresh' then i want to generate password automatically like 'SURESH' . I have root privileges also if u cant plz tel me. ex, Enter the user name: suresh output: Your new pass word is crated : SURESH so how to restore this password to that user?

As I said in my original post, use the unix passwd command to change a users password. For user suresh, a user with root privileges can do this: passwd suresh passwd then prompts you to enter a password. You can use passwd to chance your password from the command line by executing: passwd and it prompts you to enter a password. Also, as I said, since passwd is an interactive command you can't call it from a normal sh/ksh script. You have to use expect. Did you look at the link I posted?

YES I SAW THAT BUT EXPECT command is not working n my shell. But i want to do it within a script. if u can tell me how to use expect .
