Edit files in linux (mostly for beginners)
Exactly as it says in How to edit a file in linux
Simplest way to get started is to use nano. It's included in many distros including ubuntu.
$ nano filename
nano is a clone of pico. pico also seems to be included.
Later there are editors you may find that better suit your personal style -- the classics in the field are called Emacs and Vim.

It's pretty intuitive. It all happens in the console. There is a list of commands at the foot of the terminal, so the barrier to entry is low.
| Keys | Purpose |
|---|---|
| Ctrl O | Write out... i.e. SAVE. |
| Ctrl W | Where is... i.e. find text |
| Ctrl X | Exit... It warns you if you try to exit without saving. |
Now vim is also available. It's far more powerful, but with a learning curve.
It will never ever go away as long as you live. So any effort spent moving up that learning curve will continue to be of value forever.
(Early in the Foundation Series of novels by Isaac Asimov, the character Hari Seldon uses a special calculator to prove that the Galactic Empire will collapse. The conclusion is inescapable and the intelligent people begin to prepare for it. Others don't.
I'm like that, but with vim. Any simple analysis of how the future will play out proves that it is worth learning vim. It's a shocking and inescapable realization. I should begin to prepare for it. The best time to start is five years ago, the second best time is now.)
