In this short article we would like to show how in Bash pass variables from one script to second one.

Quick solution (call child script following way):

xxxxxxxxxx
 
. path/to/child/script.sh

Note: . exports all script variables to child script.

Practcal example

Edit

To see how it works we can use below example that needs to create in same directory 2 sh files.

Do following steps:

1. create scripts

a.sh file:

xxxxxxxxxx
 
#!/bin/bash
​
TEST=5
​
echo "a.sh: ${TEST}"
​
. ./b.sh

b.sh file:

xxxxxxxxxx
 
#!/bin/bash
​
echo "b.sh: ${TEST}"

2. add execution permissions for files

xxxxxxxxxx
 
chmod a+x a.sh
chmod a+x b.sh

3. run a.sh script

xxxxxxxxxx
 
./a.sh

Output:

xxxxxxxxxx
 
a.sh: 5
b.sh: 5
