Ok. I had been introduced to “Vim” (vi) quite few years ago… i think was 2005?
Before that I was using “pico” which is meant for pine or reading email client if not mistaken.
At that time , i was hardly know how to use vi .
remembering how did i always messed up whenever tried to edit cronjob using
“crontab -e” . it spawn the default editor instead of pico.
most of the system i used by then was vi..
First few attempt was the following sequence :
vi file.txt
:q! - quit without change
i - insert
:w - write to file
:wq - write to file and quit
:wq! - write and quite with override option..
doesn't care if file is not written due to permission or anything.
(that time got no sense of file permission yet.. haha)
vim -r file.txt - recover from a .swp file?
view file.txt - just view the file without altering it..
as someone else is also accessing the file.
y - for yank
d - delete
p - for paste.
3yy - for three line copy
r - for replace
v - for visual mode.
i - for insert mode.
then ..
:%s/texttomatch/replacewiththis/g - for replacing thing
gg - go to top most of current file
G - go to most bottom?
then few week back.. learnt the following..
:split . - split the screen horizontally with the current folder content.. which is clickable.
to move between the splitted window
ctrl+w
:vsplit . - split the screen vertically .. with current folder.
shift+v – to start line selection. (change to visual mode)
then followed by down arrow to highlight the line.
press y to yank..highligted line.
then move the cursor to where to put..
press p to paste..
% - to find the next closing bracket.
u - to undo
ctrl+r - to redo
:set ai - turn on auto-indent
:set noai - turn off auto-indent .. useful whenever pasted from other window.
and also the ~/.exrc with the following content.
set ts=2
set shiftwidth=2
set ai
set background=dark
I believe there are many more usage…
let’s collect it before I forgot how to use them
