How to Use the touch Command in Linux

The touch command is one of the quickest ways to create new empty files or update timestamps for existing files in Linux. It’s widely used by system administrators, developers, and anyone who works with scripts or manages lots of files. Mastering touch can boost efficiency, automate file creation, and help maintain proper timestamp records.

What Does touch Do?

Instantly creates new files without opening a text editor.
Updates access and modification timestamps for files and directories.
Can selectively change only access or modification times.
Supports batch creation of multiple files at once.

Basic Syntax

touch [options] filename

Replace filename with your desired file or directory name. Include multiple names to create several files at once.

Practical Examples

1. Creating a Single Empty File

touch resume.txt

This command makes an empty file named resume.txt in the current folder.

2. Creating Multiple New Files

touch chapter1.md chapter2.md chapter3.md

Boom! Three files land in your directory, ready for editing.

3. Using Brace Expansion for Bulk Files

touch backup_{A,B,C}.tar.gz

Creates backup_A.tar.gz, backup_B.tar.gz, and backup_C.tar.gz at the same time.

4. Update Timestamps Without Creating a File

touch -c report.txt

Only updates timestamps if report.txt exists; doesn’t create it if it doesn’t.

5. Update Only Access or Modification Time

touch -a visitors.log      # Only access time
touch -m summary.docx      # Only modification time

6. Match Timestamps to Another File

touch -r old_version.txt new_version.txt

new_version.txt now has the same timestamps as old_version.txt.

7. Set a Custom Date/Time

touch -t 202510011200.00 archive.log

Set timestamps to October 1, 2025, 12:00:00.

Important Flags

Option	Description
-a	Change access time only
-m	Change modification time only
-c	Don’t create files if they don’t exist
-r	Set times based on another file’s timestamps
-t	Set a specific date/time (format: [[CC]YY]MMDDhhmm[.ss])

Why Use touch?

Perfect for creating log placeholders, batch file templates, or empty flags for scripts.
Useful for resetting modification times and simulating activity on system files.
Plays well with shell scripting for large-scale automation and DevOps workflows.
