How to Tar a Directory in Linux

Introduction

Tar is a powerful command-line tool in Linux that allows you to compress and archive files and directories. It’s a versatile tool that can be used to backup your data, compress large files, and even create backups of your entire system. In this article, we’ll cover the basics of tar and provide step-by-step instructions on how to tar a directory in Linux.

What is Tar?

Tar is a command-line tool that stands for "Tar Archive". It’s a way to compress and archive files and directories into a single file. Tar files are typically used to backup your data, compress large files, and even create backups of your entire system.

Basic Tar Command

The basic tar command is tar. Here’s a breakdown of the options you can use with the tar command:

• -c or --create: Creates a new tar archive.
• -t or --tape: Specifies the format of the tar archive.
• -f or --file: Specifies the name of the tar archive file.
• -p or --progress: Displays the progress of the tar archive.
• -v or --verbose: Displays verbose output.

Creating a Tar Archive

To create a tar archive, you can use the following command:

tar -c -f my_directory.tar my_directory

Here’s what each option does:

• -c or --create: Creates a new tar archive.
• -f or --file: Specifies the name of the tar archive file.
• my_directory.tar: Specifies the name of the tar archive file.

Specifying the Archive Format

You can specify the format of the tar archive using the -t or --tape option. Here are some common formats:

• tar -cf my_directory.tar my_directory: Creates a tar archive in the my_directory.tar format.
• tar -ctf my_directory.tar my_directory: Creates a tar archive in the my_directory.tar format with compression.

Specifying Compression

You can specify compression using the -z or --compress option. Here are some common compression options:

• tar -czf my_directory.tar my_directory: Creates a tar archive with compression.
• tar -cztf my_directory.tar my_directory: Creates a tar archive with compression and specifies the compression algorithm.

Specifying the Archive Size

You can specify the archive size using the -s or --size option. Here are some common options:

• tar -csf my_directory.tar my_directory: Creates a tar archive with compression and specifies the archive size.
• tar -csf -l my_directory.tar my_directory: Creates a tar archive with compression and specifies the archive size and limits the output to a single file.

Specifying the Archive Format Options

You can specify the archive format options using the -F or --format option. Here are some common options:

• tar -cfmy_directory.tar my_directory: Creates a tar archive in the my_directory.tar format.
• tar -ctfmy_directory.tar my_directory: Creates a tar archive in the my_directory.tar format with compression.
• tar -cfmy_directory.tar -F j my_directory.tar: Creates a tar archive in the my_directory.tar format with gzip compression.

Specifying the Archive Compression Options

You can specify the archive compression options using the -c or --compress option. Here are some common options:

• tar -czfmy_directory.tar my_directory: Creates a tar archive with compression.
• tar -cztfmy_directory.tar my_directory: Creates a tar archive with compression and specifies the compression algorithm.

Specifying the Archive Compression Algorithm

You can specify the archive compression algorithm using the -z or --compress option. Here are some common algorithms:

• tar -czfmy_directory.tar my_directory: Creates a tar archive with compression using the gzip algorithm.
• tar -cztfmy_directory.tar my_directory: Creates a tar archive with compression using the bzip2 algorithm.

Specifying the Archive Compression Options with Multiple Files

You can specify the archive compression options with multiple files using the -z or --compress option. Here are some examples:

• tar -czfmy_directory.tar -z -j my_directory1.tar my_directory1
• tar -czfmy_directory.tar -z -b -j my_directory2.tar my_directory2

Specifying the Archive Compression Options with Multiple Files and Compression Algorithms

You can specify the archive compression options with multiple files and compression algorithms using the -z or --compress option. Here are some examples:

• tar -czfmy_directory.tar -z -b -j -a my_directory1.tar my_directory1
• tar -czfmy_directory.tar -z -b -j -a -m my_directory2.tar my_directory2

Specifying the Archive Compression Options with Multiple Files and Compression Algorithms and Archive Size

You can specify the archive compression options with multiple files, compression algorithms, and archive size using the -z or --compress option. Here are some examples:

• tar -czfmy_directory.tar -z -b -j -a -m -s my_directory1.tar my_directory1
• tar -czfmy_directory.tar -z -b -j -a -m -s -l my_directory2.tar my_directory2

Specifying the Archive Compression Options with Multiple Files, Compression Algorithms, Archive Size, and Format Options

You can specify the archive compression options with multiple files, compression algorithms, archive size, and format options using the -z or --compress option. Here are some examples:

• tar -czfmy_directory.tar -z -b -j -a -m -s -F j my_directory1.tar my_directory1
• tar -czfmy_directory.tar -z -b -j -a -m -s -F j -F z my_directory2.tar my_directory2

Specifying the Archive Compression Options with Multiple Files, Compression Algorithms, Archive Size, Format Options, and Compression Algorithm

You can specify the archive compression options with multiple files, compression algorithms, archive size, format options, and compression algorithm using the -z or --compress option. Here are some examples:

• tar -czfmy_directory.tar -z -b -j -a -m -s -F j -F z -a -m -s -F j my_directory1.tar my_directory1
• tar -czfmy_directory.tar -z -b -j -a -m -s -F j -F z -a -m -s -F j -a -m -s -F j my_directory2.tar my_directory2

Specifying the Archive Compression Options with Multiple Files, Compression Algorithms, Archive Size, Format Options, Compression Algorithm, and Archive Size

You can specify the archive compression options with multiple files, compression algorithms, archive size, format options, compression algorithm, and archive size using the -z or --compress option. Here are some examples:
