How to find list of available shells by command-line?
To list available valid login shells for use at time, type following command:
cat /etc/shells
Example:
pandya@pandya-desktop:~$ cat /etc/shells
# /etc/shells: valid login shells
/bin/sh
/bin/dash
/bin/bash
/bin/rbash
/bin/ksh93
For information about shell visit wikipedia.
You can also use
chsh -l
This will print the list of shells.
Example :-
[anurag@focused ~]$ chsh -l
/bin/sh
/bin/bash
/sbin/nologin
/usr/bin/sh
/usr/bin/bash
/usr/sbin/nologin
On at least OpenBSD and NetBSD:
$ getent shells
On (Ubuntu) Linux and many other Unices (including BSDs):
$ grep '^[^#]' /etc/shells
On Solaris, the file /etc/shells
may not exist. The list of valid shells is contained in the shells(4)
manual. On my vanilla Solaris 11.3 system, this lists the following shells:
/bin/bash /usr/bin/bash /bin/pfbash /usr/bin/pfbash
/bin/csh /usr/bin/csh /bin/pfcsh /usr/bin/pfcsh
/bin/jsh /usr/bin/jsh /sbin/jsh /usr/sbin/jsh
/bin/ksh /usr/bin/ksh /bin/pfksh /usr/bin/pfksh
/bin/ksh93 /usr/bin/ksh93 /bin/pfksh93 /usr/bin/pfksh93
/bin/sh /usr/bin/sh /bin/pfsh /usr/bin/pfsh
/bin/tcsh /usr/bin/tcsh /bin/pftcsh /usr/bin/pftcsh
/sbin/sh /usr/xpg4/bin/sh /sbin/pfsh /usr/xp4/bin/pfsh
/bin/zsh /usr/bin/zsh /bin/pfzsh /usr/bin/pfzsh
/usr/sfw/bin/zsh
It's worth noting that on my installation, neither /usr/sfw/bin/zsh
nor /usr/xp4/bin/pfsh
exists...
A shorter list of valid Solaris shells (duplicates of each shell removed):
/bin/bash /bin/ksh /bin/pfcsh /bin/pfsh /bin/sh
/bin/csh /bin/ksh93 /bin/pfksh /bin/pftcsh /bin/tcsh
/bin/jsh /bin/pfbash /bin/pfksh93 /bin/pfzsh /bin/zsh
