Useful linux commands for beginners

Beginners installed linux (in general perform the installation of Ubuntu) and it seems all cute till it's time to follow any tutorials on the internet and almost always use a little tutorials require the console and insert some linux commands. Each day more graphics applications to appear as in the console but in a graphical interface, but that does not mean that doing things from the console is more comfortable and faster.

Then, as an aid to newcomers quickly see some linux commands, The most used. We will not delve into each one because they all have many options, instead I'll just name they do.

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

pwd = Shows on what directory it is currently working.
mkdir = Create a folder or directory
rmdir = Delete a folder or directory
cd = Change to another folder

touch = Create a new file
cat = Displays the contents of a file
more = Show files one page at a time
find = Is used for searching.
diff = Show the difference between 2 files
chmod = Change the permissions on files and folders

ln -s = Create symbolic links, shortcuts

du = Disk Usage
df = Free Disk Space

ps = Status Process
ps -a = Display all processes from all users

alias = You can create your own linux commands
history = Display previously used commands (very useful!)
