How to change Bash to csh with username and password

Question

I want to change bash to csh I'm using following command which is not working chsh -s /bin/csh insite(user) insite(password).

I need to write shell script with this command
this is the output i got

chsh -s /bin/csh insite insite 
Usage: chsh [ -s shell ] [ --list-shells ] [ --help ] [ --version ] [ username ]

Solution

The reason this command is failing is because you are providing too many parameters. chsh does not accept a password on the command line, and if you are trying to change someone else's account you must be root:

sudo chsh -s /bin/csh insite

If you don't have sudo, become root by whatever means is appropriate to your situation and run

chsh -s /bin/csh insite

If you are trying to change your own shell you don't even need to be root - provided /bin/csh is listed in /etc/shells. You will have to enter your own password, though, to prove it is you who wants to change your shell.

chsh -s /bin/csh
Password: _

What error message did you get? Why do you think that chsh takes a username and password as parameters?

[insite@T37 ~]$ chsh -s /bin/csh insite insite Usage: chsh [ -s shell ] [ --list-shells ] [ --help ] [ --version ] [ username ]

Chsh command is taking Username(insite). after executing this command asking password. if i enter password manual its working. now i want to write this command in script. how can i enter password in script?

you'll likely need to use something like expect which can feed a password to chsh

@ avinash Kindly clarify whether you want to reset the password or you want to switch as insite at that time its asking password

is /bin/csh allowed ? does it appear in chsh --list-shell ?

by the way chsh would be enough to change your own shell.
