如何检查Mac OSX中可用的外壳？

Question

How can I check all the different shells that I can use in OSX Terminal application?

The default one is bash, and I know zsh because I tried and it worked. I wonder how can I check if there are any more than this two.

Answer 1

The easy way is go to /etc and check the shells file. The content is the list of shells available in Mac OSX.

The included by default are:

/bin/bash
/bin/csh
/bin/ksh
/bin/sh
/bin/tcsh
/bin/zsh

Alternatively, you can check their binaries by going to /bin and recognising them visually. Naturally, you have to know them in order to recognise them.

Answer 2

In MacOS the following command will list the available shells on your system

$ ls -l /bin/*sh
-r-xr-xr-x  1 root  wheel   618448 Nov 19 00:26 /bin/bash
-rwxr-xr-x  1 root  wheel   380016 Feb  7 16:11 /bin/csh
-r-xr-xr-x  1 root  wheel  1287040 Sep 21 00:35 /bin/ksh
-r-xr-xr-x  1 root  wheel   618512 Nov 19 00:26 /bin/sh
-rwxr-xr-x  1 root  wheel   380016 Feb  7 16:11 /bin/tcsh
-rwxr-xr-x  1 root  wheel   610288 Sep 21 00:35 /bin/zsh
