How to Compress Files Using bzip2 Command in Linux
How to Compress Files Using bzip2
in Linux
Hey there! 👋 Welcome to this Linux tutorial, brought to you by ProgramGuru.org. Today, we're going to learn how to compress files using the bzip2
command — a powerful and space-efficient compression tool available in most Linux systems.
If you’ve ever wanted to save disk space, or make your file transfers faster, bzip2
is a fantastic tool to have in your Linux toolbox. Let’s walk through it step by step.
What is bzip2
?
bzip2
is a command-line utility that compresses single files using the Burrows–Wheeler algorithm. It usually provides better compression ratios than gzip
.
Step 1: Check if bzip2
is installed
On most modern Linux distros, bzip2
comes pre-installed. But you can verify it with this command:
bzip2 --version
If it's not installed, you can add it using your package manager:
sudo apt install bzip2 # Debian/Ubuntu
sudo yum install bzip2 # RHEL/CentOS
sudo dnf install bzip2 # Fedora
Step 2: Create a sample file
Let’s create a test file to practice with:
echo "This is a test file for compression." > testfile.txt
Step 3: Compress the file
Now let’s compress it using bzip2
:
bzip2 testfile.txt
This command will replace the original file with a compressed version:
testfile.txt.bz2
Notice that the original testfile.txt
is gone — it’s now inside the compressed file testfile.txt.bz2
.
Want to Keep the Original File?
Use the -k
(keep) option:
bzip2 -k testfile.txt
testfile.txt
testfile.txt.bz2
Step 4: View the compressed file size
ls -lh testfile.txt.bz2
Step 5: Decompress the file
To unzip it back to the original form, use bunzip2
:
bunzip2 testfile.txt.bz2
Or use the -d
flag with bzip2
:
bzip2 -d testfile.txt.bz2
Bonus Tip: Compress Multiple Files?
bzip2
only works on single files. If you want to compress a whole folder or multiple files, you should first archive them using tar
:
tar -cvjf archive.tar.bz2 foldername/
This command:
-c
: creates an archive-v
: shows progress-j
: compresses using bzip2-f
: specifies the filename
Recap
bzip2 filename
→ compresses the filebunzip2 filename.bz2
→ decompresses it-k
option → keeps original filetar -cvjf
→ compresses directories
And that’s it! 🎉 You now know how to compress and decompress files using bzip2
. Keep practicing and try it on your own files. If you found this helpful, check out more Linux tutorials at ProgramGuru.org!
