This thread is a little old, I hope I dont have to make a new one for this.

On most systems the arrow keys will give you control of the cursor, however when I was first learning my arrow keys just stopped working in vim. I found the solution somewhere and it was just a simple command to run before using vim every day so i added it to my .profile and forgot about it. Now I am miles away from my work computer so have no way to look it up, so if someone knows what I am talking about and can clarify or at least post the command I think that would make a great addition to this thread. I will try to find it and post it here. If no one beats me to it.

As a new user that almost made me want to give up, I couldn't scroll and so for me there was nothing better than cat.

I am a beginner with unix, so may be my question will be very stupid.

I have problem with saving a FORTRAN's code after changing it.
I used the "vim" command to read the code, then use the "SHIFT-I" to insert some new part in the code.
After that I don't know how to save the code.
I tried the command: ":w" but it just write to the code, it can not save the code.
Thanks in advance for helping me.

Could I have another question here?
If I want to copy 19 lines in the fortran code (for example from line 1 to line 19) after using the command "vim" to read the code, what should I do?
Thank so much!

@Phamnu :
What you have to understand is :
when in vi or vim you have 2 main mode :
- insertion mode (when you type your code)
- command mode (when you want to tell vi/vim to do some specific actions, line jump, cursor move ...)
With normal bindings, to switch to command mode, press <ESC>
To switch to insert mode, you can use different command (i : insert where your cursor is, I insert at beginning of the line you are on, o, open a line under which you are, O open line above which you are.


a) <ESC> go to command mode
b) 1G go to first line
c) 19yy yank 19 lines including the line your cursor is on
d) nG go on the nth line under which you want to insert the lines
e) p paste the lines previously yanked.

Nope. vi = vi - Wikipedia, the free encyclopedia
vim = http://en.wikipedia.org/wiki/Vim_(text_editor)

vim is of course based on vi but has more features and improvements - like syntax color highlighting. Stands for 'VI iMproved"
