How do I list all available shell builtin commands?

Solution 1:

You can use compgen -b from a bash shell to get a list of the shell's builtin commands.

Solution 2:

From the terminal type:

help

From help help:

Display information about builtin commands.

Solution 3:

Alternatively you can display with enable command: (Both @karel's and @steeldriver's answer works fine.)

enable -a | cut -d " " -f 2,3

If any builtin is disabled then it is shown with -n in out put.

Example output:

$ enable -a | cut -d " " -f 2,3
