What is the touch command?

The touch command is a standard utility in Unix and Linux systems used primarily for two purposes:

1. Create Empty Files: If the specified file does not exist, touch creates a new, empty file.

   touch filename.txt

2. Update Timestamps: If the file already exists, touch updates the file's access and modification timestamps to the current time without altering the file's content.

Key Features:

• No Output: The command does not produce any output if it executes successfully.
• Multiple Files: You can create or update multiple files in one command.

  touch file1.txt file2.txt

The touch command is commonly used in scripting and file management tasks. If you have more questions or need examples, feel free to ask!
