Frequently Use Linux Command Line
Even now Linux have good desktop software like Gnome or KDE i often use Linux command line to configure and doing my work on Linux especially Ubuntu as my favorite distro. For example, writing a code and text i often use vim from shell and sometimes use modified Gedit. I found that using Linux command line much faster and lightweight. And for configuring a Linux server that far away, it’s a must for you to do it from Linux shell or ssh. And it’s fun to play with the Linux command line. And below i want to share with you, frequently use Linux command line.

LikeThere are much more important commands than that list, but the most important thing to mention about your listing: CAT is able to join files of multiple format. That's more than a simple output-editor-replacement.
E.G.:
#~ cat input_1.avi input_2.avi > output.avi
