What is Tar?

Before we dive into the process of tar a folder Linux, let’s quickly cover what tar is. Tar is a command-line tool that creates a compressed archive of files and directories. It is commonly used to:

• Compress files and directories
• Archive large datasets
• Share files with others
• Backup data

Basic Tar Command

The basic tar command is tar. Here’s a breakdown of the options and syntax:

• tar: The basic tar command.
• -c: Create a new archive.
• -f: Specify the output file name.
• -t: Specify the archive format (e.g., tar, tar.gz, tar.bz2).
• -v: Verbosity level (optional).

Creating a New Archive

To create a new archive, use the following command:

tar -c -f myarchive.tar myfolder

• -c: Create a new archive.
• -f: Specify the output file name.
• myarchive.tar: The name of the archive file.
• myfolder: The name of the folder to archive.

Specifying the Archive Format

To specify the archive format, use the -t option followed by the desired format:

tar -c -f myarchive.tar -t tar.gz myfolder

• -t: Specify the archive format.
• tar.gz: The format of the archive (tar.gz).

Adding Files to the Archive

To add files to the archive, use the following command:

tar -c -f myarchive.tar -C myfolder myfile1.txt myfile2.txt

• -c: Create a new archive.
• -f: Specify the output file name.
• myarchive.tar: The name of the archive file.
• -C: Specify the directory to archive.
• myfolder: The name of the folder to archive.
• myfile1.txt and myfile2.txt: The names of the files to add.

Specifying the Output File Name

To specify the output file name, use the -f option followed by the desired file name:

tar -c -f myarchive.tar -C myfolder -f myoutput.tar myfolder

• -f: Specify the output file name.
• myoutput.tar: The name of the archive file.

Verifying the Archive

To verify the archive, use the following command:

tar -tvf myarchive.tar

• -t: Specify the archive format.
• -v: Verbosity level (optional).
• myarchive.tar: The name of the archive file.

Removing the Archive

To remove the archive, use the following command:

tar -xf myarchive.tar

• -x: Extract the archive.
• myarchive.tar: The name of the archive file.

Advanced Tar Techniques

Here are some advanced tar techniques to keep in mind:

• Tar with compression: Use the -z option to compress the archive:

  tar -czf myarchive.tar -C myfolder -z

• Tar with multiple archives: Use the -a option to create multiple archives:

  tar -acf myarchive.tar -C myfolder -a

• Tar with multiple files: Use the -f option to specify multiple files:

  tar -cf myarchive.tar -C myfolder -f myfile1.txt myfile2.txt

• Tar with multiple directories: Use the -C option to specify multiple directories:

  tar -cf myarchive.tar -C myfolder -C mysubfolder -f myfile1.txt myfile2.txt
