Editor to share with you how to write the Shell file, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

The syntax format of the Shell file is as follows:

. Filename # Note the dot (.) A space or source filename between the file name and the file name

Example

Create two shell script files.

The test1.sh code is as follows:

#! / bin/bash# author: rookie tutorial # url:www.runoob.comurl= "http://www.runoob.com"

The test2.sh code is as follows:

#! / bin/bash# author: rookie tutorial # url:www.runoob.com# use. To refer to the test1.sh file. . / test1.sh# or use the following include file code # source. / test1.shecho "Rookie tutorial official website address: $url"

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

$chmod + x test2.sh $. / test2.sh rookie tutorial official website address: http://www.runoob.com

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