SHELL--11, Shell files contain

Like other languages, the Shell can also contain external scripts. This makes it easy to encapsulate some common code as a standalone file.

The Shell file contains the following syntax format:

. FileName # Note number (.) With a space in the middle of the file name or source filename

Instance

Create a two shell script file.

The test1.sh code is as follows:

#!/bin/bashurl= "Http://www.baidu.com"

The test2.sh code is as follows:

#!/bin/bash# use. To reference the test1.sh file. ./test1.sh# or use the following include file code # source./test1.shecho "URL: $url"

Next, we add executable permissions for test2.sh and execute:

$ chmod +x test2.sh $./test2.sh URL: http://www.baidu.com

Note: The included file test1.sh does not require executable permissions.
