How do I list the functions defined in my shell? [duplicate]

I can type alias to show a list of all the aliases.

But for functions, all I can do is grep my .bash_profile.

That only gets the ones in that file, not those defined in subsidiary files or dynamically.

Is there a more convenient way to find out what functions are currently defined?

Solution 1:

declare -F

Function names and definitions may be listed with the -f option to the declare builtin command (see Bash Builtins). The -F option to declare will list the function names only (and optionally the source file and line number).

Bash Reference Manual

Solution 2:

Assuming bash shell:

typeset -f

will list the functions.

typeset -F

will list just the function names.

Solution 3:

declare -F

will give you the names of all functions

type function_name

will give you the source for a particular function

Solution 4:

declare -F actually prints declare commands and not only function names:

$ declare -F
declare -f function1
declare -f function2

You can use compgen -A function to print only function names:

$ compgen -A function
function1
function2
