Shell Programming and Scripting

Hi,

I have a question. I know that if I want to access any variables defined in a calling script (script1.ksh) in a called script (script2.ksh) I need to export that variable in the calling script to make it available in the called script. But what about the functions in the calling script?

script1.ksh

Code:

export var1=InScript1
function todayDate
{
         echo $(date)
}

script2.ksh

Code:

 
echo $var1

If I call the script1.ksh in script2.ksh then I can access all the functions & variables (without exporting) of script1.ksh like below:

script2.ksh

Code:

 
. /home/dips/script1.ksh
 
todayDate

If suppose I don't want to include the whole of the script1.ksh but want to access only parts of it as in few variables and a function then is it possible?
-dips

Put the functions in a separate file and source them from each script that requires them.
