Creating Files

Creating Empty Files

touch creates a new empty file if it doesn't exist. If the file already exists, it updates its last-modified timestamp without changing the content.

Basic Usage

touch newfile.txt

This creates an empty file called newfile.txt in the current directory.

Creating Multiple Files

touch file1.txt file2.txt file3.txt

Why Use touch?

touch is useful for:

• Quickly creating placeholder files — you can create the file structure of a project before writing any content
• Updating timestamps — some tools check modification times to decide whether to rerun a build step
• Testing — quickly create files to test scripts that process them

Verifying Creation

touch newfile.txt
ls

Output:

docs
hello.txt
newfile.txt
notes.txt

To actually put content in a file, you use echo with output redirection (covered later), or a text editor like nano or vim.

Your Task

Create a new empty file called newfile.txt, then list the directory to confirm it was created.
