Because the Linux Foundation’s new sysadmin certification exams are performance-based, you’ll want to get as much hands-on practice with the command line as you can before test day. 

“When it comes to [performance-base] evaluation, book smarts just aren’t going to do it for you, because things don’t work exactly like you expect,” Shawn Powers, an online trainer for CBT Nuggets and editor for the Linux Journal, told Linux.com for our recent article on how to study for a certification exam.

To help admins prep for the LFCS (Linux Foundation Certified Sysadmin) exam, Tecmint has prepared a series of 10 tutorials that cover the domains and competencies outlined in the Linux Foundation’s free certification prep guide. These include topics in local system administration, local security, shell scripting, filesystem and storage, software management and the command line.  Along with the many resources outlined in the prep guide, these tutorials can help you practice and polish your skills before exam day.
