touch Command in Linux: Create and Update Files

Quick take: The touch command creates empty files and updates file timestamps. touch file creates the file if it does not exist or refreshes its modification time if it does. Add -c to avoid creating new files.

Introduction

The touch command does two simple jobs: it creates empty files and it updates the access and modification timestamps of existing ones. It is one of the quickest ways to create a placeholder file, and its timestamp control is handy in build systems and scripts.

This guide covers creating single and multiple files, updating timestamps, setting specific times, and the options that change touch's default behaviour.

Syntax

The basic syntax of the touch command is:

touch [OPTIONS] FILE...

Practical Examples

Real touch commands you can run today:

# Create an empty file (or refresh its timestamp)
touch report.txt
# Create several files at once
touch file1.txt file2.txt file3.txt
# Update timestamp without creating a missing file
touch -c maybe.txt
# Set a specific modification time
touch -d '2026-01-01 12:00' newyear.log
# Match another file's timestamp
touch -r template.txt copy.txt
# Create many numbered files with brace expansion
touch test_{1..5}.txt

Tips and Best Practices

• touch is the fastest way to create a placeholder file before you populate it later.
• Refreshing a file's timestamp with touch can trigger build tools like make to treat it as changed.
• Combine with brace expansion (touch f{1..10}.txt) to create batches of files instantly.

Final Thoughts

touch is a tiny command with two clear uses: creating empty files and adjusting timestamps. Remember -c to avoid accidental file creation and -d/-t to set precise times, and it slots neatly into scripts and build pipelines alongside ls -l and stat.
