vi editor problem

visitnag · 08-03-2008, 11:07 AM

Hi everybody,

I am working on RHEL 4es. I use vi editor for text editing. We have long length data files. To view the file without wrapping i give the command ' set nowrap ' everytime.
Typing this lengthy command everytime is boring. Is there any short cut to cut short this command.
Some times i open the files with vimdiff command. But i was told that this command may currupt the file.
Is it true? Kindly help me.

Look for the files ~/.vimrc and ~/.exec

Add the line:

set nowrap

To the first if you have that, otherwise the second. The command is compatible with both vi an vim.

I don't about your vimdiff corruption question.

editing the .vimrc will permanently open all the files with nowrap. But i dont want this. i want a short cut at vi editor i.e., at : instead of typing the lengthy set nowrap command i want to type a simple word... like :sn.

Create a map:

map <F1> :set nowrap<CR>

This one maps the F1 function key to set nowrap for you.

Kindly guide how to map. I am a newbie for mapping a key.

what i understood is...

at command prompt (in vi)

:map <press f1 key> :set nowrap<here what is CR?>

CR=carriage rtn aka enter key....

after mapping its working superbly...but when i exit the vi editor...its gone... again i have to map it when i enter freshly into the vi editor... Guide me to map the key permanently.... or some other hint... or shortcut..

Add any maps or settings you want in each edit session to your .vimrc or .exrc file.

Err, in your post #3, you said you didn't want that though ....

Mr. C. · 08-08-2008, 01:44 AM

I think the OP didn't want set nowrap, but is ok with a mapping allowing wrap disabling on demand.

Hey! i am unable to find .vimrc in my system(RHEL4ES). We have a separate user like mainsys. In this all our programs files are loaded under prog directory. when i login to mainsys the default path is like this /usr2/project/mainsys/prog. I could find .vimrc of root. But did not use it regularly. how to find .vimrc of mainsys user (group is mainsysgrp)

Just run:

vi $HOME/.vimrc

and add your mappings, then save the file.
