How to run .sh file in linux

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

The first one ( This method requires chmod to make the file meet the execution conditions (x): chmod u x datelog.sh): (Recommended learning: linux operation and maintenance)

1. In any path Next, enter the absolute path of the file /root/datelog.sh to execute the file (of course, if permissions allow)

[root@ubitername ~]# /root/datelog.sh

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

[root@ubitername ~]# cd /root
[root@ubitername ~]# ./datelog.sh

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

1. Under the file path sh plus the file name, sh datelog.sh

[root@ubitername ~]# sh datelog.sh

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

[root@ubitername ~]# cd /etc
[root@ubitername ~]# sh /root/ datelog.sh
