This article will explain in detail what the touch command in Linux can do. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Linux commonly used commands touch commands have two functions: one is to update the time tags of existing files to the current time of the system (the default), and their data will be kept intact; the other is to create new empty files.

Touch creates a new empty file

Syntax touch (option) (parameter) option-a: or-- time=atime or-- time=access or-- time=use only changes the access time;-c: or-- no-create does not create any files;-d: use the specified date and time, not the current time;-f: this parameter will be ignored and will only be responsible for solving the compatibility issue of the BSD version of the touch instruction. -m: or-- time=mtime or-- time=modify only change the change time;-r: set the date and time of the specified file or directory to be the same as the date and time of the reference file or directory;-t: use the specified date time instead of the current time;-- help: online help;-- version: display version information. Parameter file: specifies the list of files to set the time property.

Instance touch ex2 creates an empty file ex2 in the current directory, and then, using the ls-l command, you can find that the size of the file ex2 is 0, indicating that it is an empty file.
