Thanks James! On a related note, I was thinking this morning that I really
need to bone up on vi as there are times when it's the editor of choice
(like booting up in rescue mode). Way back when, I created a little cheat
sheet with basic commands and such on it which is below. Probably old hat
to most of you, but if there are other Linux newcomers (I hate the phrase
"newbie") maybe they'll find it useful. Back in '95 I took a UNIX class, so
these are notes from that. I assume that all the commands work as
advertised. Some may have been deprecated or superceded. If so, please
feel free to correct me...
Shortform for the "vi" Unix text editor.
Note that upper and lower case is very important.
Edit a file
===========
vi filename where <filename> is the file to edit
Cursor movement
===============
h cursor left w next word
l cursor right b previous word
k cursor up
j cursor down
Text insert and delete
======================
vi has two modes, command mode and text insertion mode.
To enter the insert mode type either i or a,
i insert text at cursor
a insert text one position right of cursor
To exit text mode and enter command mode, press the ESC key
x delete one character at cursor
dd delete current line
dw delete from cursor to end of word
cw enters change word mode and changes word (from cursor to end
of word) to what you key in. Exit cw by pressing the ESC key.
u undo previous command
Search and replace
==================
/string search forward for <string>, case sensitive
?string search backwards for <string>, case sensitive
n repeat previous search
Save and exit
=============
ZZ save current file and exit vi
:q! exit vi without saving current file
