Introduction: The Learn on Demand Systems' Configure Links in Linux is a premium Cybrary lab that trains students to learn the command-line utilities that are used to make links between files i.e. ln in the Command Line Interface as well as create hard and symbolic links while checking for broken links too. The Configure Links in Linux is intended for Intermediate level students and learners.

The Learn on Demand Systems' Configure Links in Linux Lab is aimed towards the System Administrator work profile. Upon successful completion of Learn on Demand Systems' Configure Links in Linux Lab, the student will be able to create and analyze hard and symbolic link files using ln User Command as well as manage these linked files. Learn on Demand Systems' Configure Links in Linux Lab takes 30-45 minutes to complete for most students.

Skills/Activity Breakdown: The Configure Links in Linux Lab aims at teaching students to create hard and symbolic links between files using ln User command in Linux. Also, it includes a tutorial to create files and directories to link them using the ln command while also verifying their link path. A student learns good usage of creating by-default hard and symbolic links of files. Working with the ln command-line utility allows administrators to create and analyze as well as manage hard and symbolic links made in the Linux configuration files.

The Configure Links in Linux Lab also aims at teaching students to check for broken links in the hard and symbolic links of files in Linux. Also, it includes a tutorial to check for broken links inside directories and using the find General User Command to locate for broken links of files inside the directories. A student learns good usage of creating and analyzing hard and symbolic links as well as check for existing broken links. Working with the find General User Command allows administrators to locate the Linux configuration files which are linked.

The Configure Links in Linux Lab teaches students to manage files inside directories that are linked via hard or symbolic links. Students will receive a hands-on the following variety of file management and general user tool command-line utilities as mentioned here: ls, pwd, find, cd, ln, cat, rm, grep.

Completion of Learn on Demand Systems' Configure Links in Linux Lab means that the student has demonstrated the ability to use Linux Command Line tool ln to create ad analyze hard and symbolic links in the directories and check for broken links as well as using the general user command-line utility find in Linux environment.

Scenario: You are a system administrator for a company that uses Linux servers. You need to find Linux configuration files inside the /var directory that are linked, many of which will be Symbolic links. You will create and analyze hard and symbolic link files using ln and find, and then you will edit as well as delete the files. You will also use file management commands.

Environment: You will use a default installation of CentOS 7 Linux with the Server with GUI package installed. Non-privileged accounts have been created for you. You will be guided through the process of adding software if necessary.

Learn on Demand Systems' Configure Links in Linux Lab is a part of the Linux: Command-Line and File System-Challenge Series Learning path presented by Cybrary and the lab is created by Learn on Demand Systems.
