10
points
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):
. path/to/child/script.sh
Note:
.exports all script variables to child script.
Practcal example
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:
#!/bin/bash
TEST=5
echo "a.sh: ${TEST}"
. ./b.sh
b.sh file:
#!/bin/bash
echo "b.sh: ${TEST}"
2. add execution permissions for files
chmod a+x a.sh
chmod a+x b.sh
3. run a.sh script
./a.sh
Output:
a.sh: 5
b.sh: 5
