About this Hands-on Lab

In this hands-on lab, we will practice archiving and compression. Archiving is often used for backing up and moving files, and the ability to create compressed archives is a fundamental skill for a systems architect. By the end of this lab, you will be familiar with creating and working with archives.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Create a Normal Archive
  1. Use the following command to create a tarball of the ~/Practice folder named archive.tar:
    tar cvf archive.tar Practice/
Add the File `~/extra.txt` to `archive.tar`
  1. Use the following command to add the file ~/extra.txt to the existing tarball:
    tar rf archive.tar extra.txt
Create a Compressed Archive
  1. Now create another tarball, but this time, compress it during creation with the following command:
    tar czf archive.tgz Practice/
Compress the Normal Archive
  1. Use the gzip utility to compress the first tarball (archive.tar) with maximum compression:
    gzip -9 archive.tar
  2. This will compress the file and rename it archive.tar.gz.
Extract the File `Practice/Test/version.txt` from `archive.tar.gz`
  1. Use the following command to extract the file Practice/Test/version.txt from the compressed archive archive.tar.gz:
    tar xzf archive.tar.gz Practice/Test/version.txt
  2. This will extract the file to the existing path and overwrite the file if it exists.

Additional Resources

You have been asked to create two archives of the folder ~/Practice and work with them as follows:

  1. Create a normal archive of ~/Practice without any compression and name it archive.tar.
  2. Add the file ~/extra.txt to archive.tar.
  3. Create a gzip compressed archive and name it archive.tgz.
  4. Use gzip to compress archive.tar with maximum compression, and compare the file sizes.
  5. Extract the file Practice/Test/version.txt from archive.tar.gz.

Note: Please wait an extra minute before connecting via ssh to make sure the lab is fully provisioned.
