Linux course

Question

I want to make some lessons in Linux for SoloLearn. To make it easy for me I would love if people who know a bit Linux will take two minutes and write about one Linux command.
Example :
cd - change directory is a command line command to change the current working directory in operating system such as Unix. (same in windows cmd)

Answer 1

ls - list files.
A command that lists the files and directories in the current working directory.

Answer 10

Off-topic but related!
It would have been great if Sololearn added a Linux course into the mix. Linux skills are essential nowadays.
By the way, type 50 most frequently used Linux commands in Google search and most of them will explain what each command does.
