How to Use tar Command in Linux: Syntax and Examples

The tar command in Linux is used to create and extract archive files. Use tar -cf archive.tar files to create an archive and tar -xf archive.tar to extract it.

Syntax

The basic syntax of the tar command is:

• tar [options] [archive-file] [file or directory]

Here, options control the action (create, extract, list), archive-file is the name of the tar file, and file or directory specifies what to archive or extract.

bash

tar [options] [archive-file] [file or directory]

Example

This example shows how to create a tar archive named backup.tar from the documents folder and then extract it.

bash

tar -cf backup.tar documents

tar -xf backup.tar

Common Pitfalls

Common mistakes include:

• Forgetting the -f option, which specifies the archive file name.
• Using -c (create) and -x (extract) together, which is invalid.
• Not specifying the correct path, causing unexpected files to be archived or extracted.

bash

tar -cf archive.tar file1 file2  # Correct way to create

# Wrong: missing -f option
# tar -c archive.tar file1 file2

# Wrong: mixing create and extract
# tar -cxf archive.tar file1

# Right: extract
# tar -xf archive.tar

Quick Reference

Option	Description
-c	Create a new archive
-x	Extract files from an archive
-t	List contents of an archive
-f	Specify archive file name
-v	Verbose output showing files processed
-z	Compress archive with gzip
-j	Compress archive with bzip2

Key Takeaways

Use -c with -f to create archives and -x with -f to extract them.

Always specify the archive file name with -f to avoid errors.

Use -v for verbose output to see what files are processed.

Compress archives with -z (gzip) or -j (bzip2) for smaller files.

Avoid mixing create and extract options in the same command.
