How to update file timestamps?

To update the timestamps of a file in Bash, you can use the touch command. This command will change the last modified and last accessed times of the specified file(s) to the current time.

Example:

touch filename.txt

Explanation:

• This command updates the timestamps of filename.txt to the current date and time.
• If the file does not exist, it will create an empty file with that name.

Updating Multiple Files:

You can also update multiple files at once:

touch file1.txt file2.txt file3.txt

If you need to set a specific timestamp instead of the current time, you can use the -t option:

touch -t 202301011200 filename.txt

This sets the timestamp to January 1, 2023, at 12:00 PM.
