I have defined a few different functions in my .bash_profile. I usually remember the name of function but want to take a quick peek in the code before I run it.
In my .bash_profile I have the following:
gpm () { echo "git pull origin master" git pull origin master } Now I want to run something like this in Bash:
$ <something> gpm Result expected: Don't execute the function just print out the function definition itself.

Typically, when writing bash scripts, we use echo to print to the standard output. echo is a simple command but is limited in its capabilities. To have more control over the formatting of the output, use the printf command. The printf command formats and prints its arguments, similar to the C printf() function.
When a bash function ends its return value is its status: zero for success, non-zero for failure. To return values, you can set a global variable with the result, or use command substitution, or you can pass in the name of a variable to use as the result variable.
Defining Bash Functions Functions may be declared in two different formats: The first format starts with the function name, followed by parentheses. This is the preferred and more used format. The second format starts with the reserved word function , followed by the function name.
We need to use the type command or declare command to find and display bash shell function source code under Linux and Unix.
EDIT: The best answer isn't this one, but the other one below.
What this answer used to say is that you can get a function definition in bash using the type builtin, e.g. type gpm. However, using declare as described in the other answer is better in every way.

declare -f gpm will just print the function definition of function gpm with no other text.
