They are all editors, vi , vim or emacs. I would guess that emacs is in an additional package not included in the default install and is an editor that full time programmers like. You can use any of them for reading but that is a bit of overkill. Unix also has "view" which behaves like vi but by default is read only. You can also read files with "cat", "more" or "less" with "less" being the best option since it lets you page back and forward through the file.
As I said in an earlier reply, buy O'Reilys "UNIX in a Nutshell" since it has a brief synopsis of all these commands as well as sections on shells, awk, sed etc. Well worth the price since it will get you going on all things UNIX. vattini giacomo wrote, On 01/31/10 12:24: > Could you explain,what you mean using vi?? > I use vi when i have to modify files or create them. > Do you use vi for reading or anythingelse? > I do not understand.... >
