Original: https://www.runoob.com/linux/linux-shell-include-file.html

And other languages, Shell may also include an external script. This makes it easy to package some common code as a separate file.

Shell syntax file contains the following:

. Filename # Note the dot (.) And filename middle of a space

or

source filename

Examples

Create two shell script files.

test1.sh code is as follows:

#!/bin/bash
# Author: rookie Tutorial
# Url: www.runoob.com

url="http://www.runoob.com"

test2.sh code is as follows:

#!/bin/bash
# Author: rookie Tutorial
# Url: www.runoob.com

# Use. To cite test1. SH file
. ./test1.sh

# Include files or use the following codes
# source ./test1.sh

echo  " rookie tutorial official website address: $ url "

Next, we add executable permission to test2.sh and execute:

$ Chmod . + Test2 the X- SH  
$. / Test2. SH  
rookie tutorial official website address:: HTTP // www.runoob.com

Note: The file does not need to be included test1.sh executable permission.
