Useful linux commands for beginners

Useful linux commands for beginners

 

Beginners installed linux (generally perform the installation of Ubuntu) and everything seems nice until it's time to move some tutorial online tutorials and almost always require a little handle and insert some console commands for linux.  Increasingly appear to graphical applications as in the console but in a graphical interface, but that does not mean that doing things from the console is more convenient and faster.

 Then as help novice quickly see some commands for linux, the most used.  We will not delve into each one because they all have many choices, instead I'll just name they do.

ls = Sample files and folders
ls-a = Displays files and folders, including hidden files
ls-l = Displays files and folders with more info such as permits
ls-R = Displays files and folders recursively.

 = rmdir Deletes a folder or directory
cd = Change to another folder

touch = Create a new file

more = Sample files one page at a time

du = Disk Usage
df = Free Disk Space

ps = Process State
ps-a = Displays all processes from all users

alias = Allows you to create your own commands for linux

 These are obviously not all and it is up to you to investigate further and learn to use them but with this review I hope you find it easier
