Calling shell functions from another shell script

Shell Programming and Scripting
1

Hi,

I have a query ..
i have 2 scripts say 1.sh and 2.sh
1.sh contains many functions written using shell scripts.
2.sh is a script which needs to call the functions definded in 1.sh
function calls are with arguments.
Can some one tell me how to call the functions from 2.sh?

Thanks in advance.

I have done a bit more research.
I know this is not possible especially with arguments. but still there should be a way out ..

1.sh:

#!/bin/ksh
fun1() {
  typeset arg1="${1}"
  echo "in 1.sh::fun1 arg1->[${arg1}]"
}

2.sh:

#!/bin/ksh
echo "in 2.sh"
. 1.sh

fun1 "foo"

There is a better way of doing what you want to do using FPATH and/or autoload

For example, suppose you create the following directory within your home directory and put your function scripts in this directory. The filename should be the function name.

mkdir ~/.kshfunctions

In your .kshrc file, define the FPATH variable to point to that directory:

export FPATH=~/.kshfunctions

Functions will then be loaded on an as needed basis and results in faster script startup. To get a listing of which functions are actually currently loaded, just type 'functions' at the prompt. Use whence to find a function.

#!/usr/bin/ksh93
echo "in 2.sh"
fun1 "foo"

# fun1
function fun1
{
  print "In function fun1 arg1->[$1]"
}

$./2.sh
in 2.sh
In fun1 arg1->[foo]

That is limited to the Korn shell and will not work in any other shell.

Yes, I agree, it is limited to ksh93.
