How to Tar the File in Linux

Introduction

Tar is a powerful command-line tool in Linux that allows you to compress and archive files. It’s a versatile tool that can be used to create backups, compress large files, and even create archives for software installation. In this article, we’ll cover the basics of tar and provide step-by-step instructions on how to use it to tar a file in Linux.

What is Tar?

Before we dive into the how-to, let’s quickly cover what tar is. Tar is a command-line tool that stands for "tar archive." It’s a way to compress and archive files, making it easy to share or transfer large files over the network. Tar files are typically compressed using the gzip or bzip2 algorithms, which can be compressed using the tar command.

Basic Tar Command

The basic tar command is tar [options] file1 file2 file3.... Here’s a breakdown of the options:

• tar: This is the command itself.
• [options]: This is the list of options that follow the command.
• file1 file2 file3...: This is the list of files that you want to tar.

Common Tar Options

Here are some common tar options that you can use:

• -c: This option creates a new archive file.
• -t: This option creates a new archive file with a .tar.gz or .tar.bz2 extension.
• -v: This option increases the verbosity of the output.
• -V: This option displays the version of tar.
• -f: This option specifies the output file name.
• -s: This option specifies the compression level.

Creating a New Archive File

To create a new archive file, use the -c option followed by the -f option. For example:

tar -c -f my_file.tar my_file.txt

This will create a new archive file called my_file.tar that contains the contents of my_file.txt.

Compressing a File

To compress a file, use the -c option followed by the -f option. For example:

tar -c -f my_file.tar my_file.txt

This will create a new archive file called my_file.tar that contains the contents of my_file.txt.

Creating an Archive with Multiple Files

To create an archive with multiple files, use the -c option followed by the -f option. For example:

tar -c -f my_file.tar my_file1.txt my_file2.txt

This will create a new archive file called my_file.tar that contains the contents of my_file1.txt and my_file2.txt.

Extracting an Archive

To extract an archive, use the -x option followed by the -f option. For example:

tar -xvf my_file.tar

This will extract the contents of my_file.tar and place them in the current working directory.

Common Tar Commands

Here are some common tar commands that you can use:

• tar -xvf: This command extracts the contents of an archive.
• tar -xvf -c: This command creates a new archive file.
• tar -xvf -c -f: This command compresses a file.
• tar -xvf -c -f -s: This command compresses a file with a specified compression level.

Tips and Tricks

Here are some tips and tricks to keep in mind when using tar:

• Use the -v option to increase the verbosity of the output.
• Use the -V option to display the version of tar.
• Use the -s option to specify the compression level.
• Use the -f option to specify the output file name.
• Use the -c option to create a new archive file.
• Use the -t option to create a new archive file with a .tar.gz or .tar.bz2 extension.
