How to run .sh files in Linux system

There are two ways to run .sh files in Linux system. For example, I have a datelog.sh file in the root directory.

The first method (this method requires chmod to make the file executable (x): chmod u+x datelog.sh):

1. In any path, enter the absolute path of the file /root/datelog.sh to execute the file (of course, if the permission is allowed)

2. cd to the directory of the datelog.sh file, and then execute ./datelog.sh

The second method (this method does not require the file to have executable permissions to run):

1. Add the file name to the file path, sh datelog.sh

2. In any path, add the file path and file name to sh: sh /root/ datelog.sh

Double-click the sh file in the desktop environment to run:

Mac:

1. Change the suffix sh to command: hello.sh->hello.command

2. Modify the executable permission: chmod u+x hello.command

Ubuntu:

1. Modify the executable permission: chmod u+x hello.sh

2. Open any folder and select [Edit] -> [Preferences] in the upper left corner.

Select [Run executable text files when opening them] to double-click to run.
