Calling on function from file??

douknownam · #1 (**permalink**) 08-22-2008

This may sounds dumb, but can I call on a function from a file? For example, I have a function file full of functions like below (no shell designation):

Code:

func { echo "blah blah blah 1" }

func2 { echo "blah blah blah 2" }

func3 { echo "blah blah blah 3" }

Am I able to call on any one of these specific functions from another script? If so, how? TIA

(Talking about bash)

Yes, you can use those functions from another file if they have the correct syntax which is not the case.

For bash functions you could have a file say file_number_one.sh:

Code:

function func { echo "bla bla bla1"; }

and then from another script you could have:

Code:

. ./file_number_one.sh

func

ya exactly..
for that you have to source your script as redoubtable suggested..

As an aside, function is a Bashism. The POSIX way to declare a function is

Code:

func () { body of function; }

I care because it bit me when I switched shells (or rather, Ubuntu switched shells on me).
