touch

The touch command in Linux is used for file management. It creates an empty file if it doesn’t exist or updates the access and modification times of an existing file to the current time.

Examples:

touch mynewfile.txt

This command creates mynewfile.txt if it doesn’t already exist.

touch updatedfile.txt

If updatedfile.txt exists, its access and modification times are set to the current time.

touch file1.txt file2.txt

Creates both files if they don’t exist; updates timestamps if they do.

The touch command is versatile for creating files and managing timestamps. It’s handy for developers and system administrators for tasks like logging and ensuring file integrity.
