tar Command Examples in Linux¶

Introduction¶

These examples show practical ways to use tar on a Linux terminal. Each example is written so you can adapt it for administration or troubleshooting.

Example 1: Basic Usage¶

tar -cf logs.tar /var/log

This is the simplest form of the command and is a good starting point before adding options.

Example 2: Common Admin Task¶

tar -tf logs.tar

This example reflects a common task on RHEL, Rocky Linux, AlmaLinux, or similar systems.

Example 3: Useful Option¶

tar -xf logs.tar

This option helps narrow the result, change behavior, or handle a more realistic target.

Example 4: Real-World Scenario¶

tar -czf app-backup.tar.gz /srv/app

Use this pattern when the task moves beyond a single basic command.

Example 5: Verification¶

tar -tf app-backup.tar.gz | head

Example output:

srv/app/
srv/app/app.conf
srv/app/bin/start.sh

Common Mistakes¶

• Forgetting -f before the archive filename.
• Extracting an archive in the wrong directory and scattering files.
• Assuming tar compression is enabled unless you specify an option such as -z.

Quick Reference¶

tar -cf logs.tar /var/log
tar -tf logs.tar
tar -xf logs.tar
tar -czf app-backup.tar.gz /srv/app
tar -tf app-backup.tar.gz | head
