How to change the shell for an already existing user – Unix/Linux

We can change the shell of a user by using the ‘usermod’ command. Some common types of shells are listed below:
> /bin/bash
> /bin/ksh
> /bin/csh
> /bin/sh
> /sbin/nologin
etc…

We can find out the shell details from the ‘passwd’ file under ‘/etc’ location.

Example:
Display shell details of the user ‘me’

[root@localhost ~]# grep -w me /etc/passwd
me:x:502:502::/home/me:/bin/bash

Shell is : /bin/bash

How to change the shell via command line?
The usermod command with switch ‘s’ is used to change the current shell of a user. Other useful usermod switches.

Example:

[root@localhost ~]# usermod -s /sbin/nologin me
[root@localhost ~]# grep -w me /etc/passwd
me:x:502:502::/home/me:/sbin/nologin

The shell changed to “/sbin/nologin

That’s it!! 🙂
