How to tar a file in Linux using command line

The procedure is as follows to tar a file in Linux:

1. Open the terminal app in Linux
2. Compress an entire directory by running tar -zcvf file.tar.gz /path/to/dir/ command in Linux
3. Compress a single file by running tar -zcvf file.tar.gz /path/to/filename command in Linux
4. Compress multiple directories file by running tar -zcvf file.tar.gz dir1 dir2 dir3 command in Linux

How to create tar a file in Linux

Say you want to compress an entire directory named /home/vivek/data/:
$ tar -czvf file.tar.gz /home/vivek/data/
To compress multiple directories and files, execute:
$ tar -czvf file.tar.gz /home/vivek/data/ /home/vivek/pics/ /home/vivek/.accounting.db
One can use bzip2 compression instead of gzip by passing the -j option to the tar command:
$ tar -cjvf file.tar.bz2 /home/vivek/data/
Where,

• -c : Create a new archive
• -v : Verbose output
• -f file.tar.gz : Use archive file
• -z : Filter the archive through gzip
• -j : Filter the archive through bzip2

How to exclude directories and files when using tar

You can exclude certain files when creating a tarball. The syntax is:
$ tar -zcvf archive.tar.gz --exclude='dir1' --exclude='regex' dir1
For example, exclude ~/Downloads/ directory:
$ tar -czvf /nfs/backup.tar.gz --exclude="Downloads" /home/vivek/

How do I view files stored in an archive?

Now you have an archive, to list the contents of a tar or tar.gz file using the tar command:
$ tar -ztvf file.tar.gz
$ tar -jtvf file.tar.bz2

How do I extracting an archive?

You can extract an archive or tarball with the tar command. The syntax is:
$ tar -xzvf file.tar.gz
$ tar -xjvf file.tar.bz2
Want to extract the contents of the archive into a specific directory such as /home/vivek/backups/? Try passing the -C DIR option:
$ tar -xzvf my.tar.gz -C /home/vivek/backups/
$ tar -xjvf archive.tar.bz2 -C /tmp/

• -x : Extract files from an archive
• -t : List the contents of an archive
• -v : Verbose output
• -f file.tar.gz : Use archive file
• -C DIR : Change to DIR before performing any operations
• --exclude : Exclude files matching PATTERN/DIR/FILENAME
