Tar Command: Archiving Files From the Command Line

The Tar Command in Linux: An Introduction

The tar command is an essential tool for managing and archiving files in Linux systems. It allows you to combine multiple files and directories into a single archive file, making it easier to transport or store them. The tar command is also useful for extracting files from an archive or viewing the contents of an archive.

In this blog, we'll take a closer look at what the tar command is, how to use it, and what its various options and switches are.

The name "tar" is short for "Tape Archive", reflecting the original use of tar for backing up files to magnetic tapes. Nowadays, tar is widely used for archiving and compressing files on a variety of storage media, including hard drives, USB drives, and cloud storage.

Creating a Tar Archive

To create a tar archive, use the following command:

cssCopy code
tar -cf [filename].tar [files or directories to archive]

The options used in this command are:

• c: Create a new archive.

• f: Specify the name of the archive file to be created.

For example, to create a tar archive of an example demo directory, you would run the following command:

tar -cf demo.tar demo

This will create a tar archive named docs.tar in the current directory, containing the contents of the docs directory.

Viewing the Contents of a Tar Archive

To view the contents of a tar archive, you can use the following command:

tar -tf [filename].tar

The options used in this command are:

• t: List the contents of the archive.

• f: Specify the name of the archive file to be listed.

For example, to view the contents of the docs.tar archive, you would run the following command:

tar -tf demo.tar

This will display a list of all the files and directories contained in the docs.tar archive.

demo_file1
demo_file2
demo_file3

Extracting Files from a Tar Archive

To extract files from a tar archive, use the following command:

tar -xf [filename].tar

The options used in this command are:

• x: Extract the contents of the archive.

• f: Specify the name of the archive file to be extracted.

For example, to extract the contents of the docs.tar archive, you would run the following command:

tar -xf docs.tar

This will extract the contents of the docs.tar archive into the current directory. You can specify a different directory for the extracted files by using the C option followed by the path to the desired directory, for example:

tar -xf docs.tar -C /path/to/directory
