RHCSA 1.4: Archives and compression

Creating a compressed archive, extracting one file from it, compressing a copy while keeping the original, and an archive that keeps owners, permissions, SELinux contexts and ACLs.

Before you start

The lab installs bzip2, and creates users dana and erik. A file in dana's home directory, shared.txt, has an ACL that lets erik read it.

Tasks

1. Create a bzip2-compressed archive of /etc named /root/etc-backup.tar.bz2.
2. Extract only etc/hostname from that archive into /tmp/restore.
3. Compress a copy of /var/log/messages in /tmp with gzip, keeping the uncompressed copy.
4. As root, archive /home with gzip so that owners, permissions, SELinux contexts and ACLs are kept, to /root/home.tgz.

Hints

• tar -cjf; file, tar -tf.
• tar -xf ARCHIVE -C DIR MEMBER; the directory must exist first.
• gzip -k, or gzip -c FILE >FILE.gz.
• tar --selinux --acls --xattrs -czf; tar -tvzf.
