Command line, are you afraid ?

There are many editors on the command line and unlike GUI-editors they are fast, very powerful and most importantly reliable, of course I will not enter the ViM/Emacs debate here, everyone has his own tasted and I respect that, for that reason I will only talk about the editor I use which is ViM, I’ve never truly explored emacs hence I won’t be able to provide accurate information about it and I prefer not to mention false information…
First I will begin with the very basic editor, nano/pico, it’s the same editor but it is installed in different names on different distributions, for example on Gentoo it’s nano while on Debian/Ubuntu it’s pico try both to know which one, for the sake of this article I will assume it is nano.
$ nano
To open up a simple editor window, just move around within, write all what you want inside and once you are done you need to save the file using Ctrl+O, nano will ask you where to save, just put the name and press Enter. NOTE: if you enter a filename without a path, the file will be saved in the working directory ( the folder you were in before opening nano ), once that is done you need Ctrl+X to quit nano. You can also use Ctrl+W to search within the file, for more information press Ctrl+G.
$ vim
To open up the ViM editor (ViM stands for VI (Spelled Vee-Eye) Improved), ViM will open in normal mode which means that if you all keys are commands not text, to start typing text press the key `i`, once you are done just hit Esc to revert back to normal mode then type `:w filename` ( Notice the text in the status bar ) and hit enter, then use `:x` to quit… For more information you should check Vim Official website.
