Try "sourcing" the file :
Code:
. /path/to/file_containing_functions

dot - execute commands in the current environment

A simple example:

Code:
$ cat Add.fn
Add ()
{
    echo $(($1 + $2))
}
$
$ cat test.sh
#! /bin/bash
. ./Add.fn

Add 2 3
$
$ ./test.sh
5
$

I would also like to call some variables in the file but which are outside the function. Is that possible. For example, having some settings.

Code:
$ cat Add.fn
tst="Hello"
Add ()
{
    echo $(($1 + $2))
}
$
$ cat test.sh
#! /bin/bash
. ./Add.fn

echo "$tst"
Add 2 3
$
$ ./test.sh
5
$

Works. I would need to get the path to the bash scripts directory though.

I put my scripts in the location
Code:
/home/tcdata/tatsh/trunk/hstmy/bin/bash

Then go to my test directory and do things as shown
Code:
cd /home/tcdata/tatsh/branches/test
/home/tcdata/tatsh/trunk/hstmy/bin/bash/tsimplex.bash        # run script

Need to get the path of the bash files. In tsimplex.bash I need to capture the string path in the calling sequence of tsimplex.bash.
Code:
/home/tcdata/tatsh/trunk/hstmy/bin/bash

What is the way to achieve this?

dirname $0 will get you the parent directory of the current script.

EDIT: or, more exactly, it will strip the trailing element from whatever the script was called as - /tmp/x.sh with return '/tmp', ./x.sh will return '.'.
