Editor to share with you the use of linux touch command to create files, I believe that most people do not know much, so share this article for you to learn, I hope you will learn a lot after reading this article, let's go to learn the method!

The touch command has two functions: one is to create a new empty file, and the other is to change the timestamp attribute of an existing file.

The touch command updates the access time and modification time of the specified file based on the current system time. If the file does not exist, a new empty file will be created unless the "- c" or "- h" options are specified.

Note: when modifying the time attribute of a file, the user must be the owner of the file or have access to write to the file.

Syntax format: touch [parameters] [file]

Commonly used parameters: coach

-a change the read time record of the file-m change the modification time record of the file-r use the time record of the reference file, the effect is the same as-- file-c does not create a new file-d set the time and date, you can use a variety of different formats-t to set the time record of the file, the format is the same as the date command-- no-create does not create new files-- help displays help information

-- version lists version messages
