VI Text Editor

The VI Text Editor deserves its own chapter. While Linux comes with many editors, VI is one of the most powerful. Other commands sometimes use identical syntax to VI (sed comes to mind). So, knowing something about VI, or at least demystifying its essential functions (how to open a file, save, quit or quit without saving), is very important.

VI Text Editor

The user will become more comfortable with the other functions of VI as they use the editor. An alternative would be to use nano which comes installed by default in Rocky Linux. While not as versatile, it is simple to use, straightforward, and gets the job done.

Backup and Restoration

Backup and Restoration is essential info for the System Administrator. Linux comes with many software solutions to enhance backups (rsnapshot, lsyncd, etcetera.). It is valuable to know the essential components of the backup that exist within the operating system. We investigate two tools: tar and the less widespread cpio in this chapter.
