Hi Zaxxon,
Thank you vm for your inputs...
Actually, the above provided code is part of my script.. I'm trying to connect to a server and there i'm changing my used id to some admin account id using sudo command..
When i try this sudo through command line or through script also, it's returning password prompt to enter my passwd.
so when i am trying to change the admin account id... i used above small code there. It's just to automate the script execution without manual intervention.
And we have our credentials in a zip file.. and it'll be in our home dir with 600 perm. so no one can even read the file. whoever execute the script, it has to take their passwd from their home dir to change the sudo account....
I hope you are bit clear now.. And still I've to try your above command to check whether it's asking the passwd or not.
Can you please provide your valuable inputs and suggestions on this..?
Thanks again.
Regards,
VRN

CHSH(1) User Commands CHSH(1)
NAME
chsh - change login shell
SYNOPSIS
chsh [options] [LOGIN]
DESCRIPTION
The chsh command changes the user login shell. This determines the name of the user's initial login command. A normal user may only change
the login shell for her own account; the superuser may change the login shell for any account.
OPTIONS
The options which apply to the chsh command are:
-h, --help
Display help message and exit.
-R, --root CHROOT_DIR
Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory.
-s, --shell SHELL
The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.
If the -s option is not selected, chsh operates in an interactive fashion, prompting the user with the current login shell. Enter the new
value to change the shell, or leave the line blank to use the current one. The current shell is displayed between a pair of [ ] marks.
NOTE
The only restriction placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the superuser,
and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh
in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell
back to its original value.
FILES
/etc/passwd
User account information.
/etc/shells
List of valid login shells.
/etc/login.defs
Shadow password suite configuration.
