Include Files in Bash

Similar to other programming languages which allow to include other files to a file, Bash scripting also allows to include (source) another shell script file to script file.

For example, to include config.sh script to current script file use following syntax, where config.sh is available in the same directory of the current script.

#!/bin/bash

source other-file.sh

#!/bin/bash

source other-file.sh

Include Shell Script in Other Shell Script

For this example, First, I have created a data.sh file with the following content.

#!/bin/bash

id=100
name="TecAdmin"

#!/bin/bash

id=100

name="TecAdmin"

Now create another file show.sh, which includes data.sh file.

#!/bin/bash

source data.sh

echo "Welcome $name"
echo "Your id is $id"

#!/bin/bash

source data.sh

echo "Welcome $name"

echo "Your id is $id"

Execute script show.sh in a terminal and view the results:

./show.sh

Welcome TecAdmin
Your id is 100
