This article brings you how to use the MD5 value of the inux recording command. Most of the knowledge points are often used by everyone, so I will share them for you as a reference. Let's follow the editor and have a look.

1. Record the current command:

Sh CheckCommDDCW.sh

two。 Record new commands or modified commands (the keyword add can be replaced with any non-empty string):

Sh CheckCommDDCW.sh add

The code is as follows:
