Export command in shell script?



Issue


Suppose in a program a line is there:

XYZ='/home/abc/pqr/' 
;;;;;;etc 


and then
what will happen if i write a command:
export XYZ 

Solution


The issue is that scripts run in a private subshell, and therefore don't affect the shell that called them.

If we pretend that we have a script like this:
Code:


#!/bin/bash 
# Name: test_script 

export OOGA=echo 'ooga' 
export BOOGA=echo 'booga' 


Then we can add it to the current shell by using the source command:
Code:


source test_script

Note


Thanks to kupendra for this tip on the forum.
