Can bash show a function's definition?

Question

Is there a way to view a bash function\'s definition in bash?

For example, say I defined the function foobar

function foobar {
    echo          


        

Answer 1

set | sed -n '/^foobar ()/,/^}/p'

This basically prints the lines from your set command starting with the function name foobar () and ending with }

Answer 2

Use type. If foobar is e.g. defined in your ~/.profile:

$ type foobar
foobar is a function
foobar {
    echo "I'm foobar"
}

This does find out what foobar was, and if it was defined as a function it calls declare -f as explained by pmohandras.

To print out just the body of the function (i.e. the code) use sed:

type foobar | sed '1,3d;$d'

Answer 3

You can display the definition of a function in bash using declare. For example:

declare -f foobar

Answer 4

set | grep -A999 '^foobar ()' | grep -m1 -B999 '^}'

with foobar being the function name.
