General Spell Rules


Clipboard

Setting Vim to use General Clipboard in Linux

When installing a new linux version, often the general clipboard register in vim (“*) does not work with the general system clipboard.

One way to determine if your version of vim supports X which is required for general clipboard support is to type the following in bash :

vim --version | grep clip

If you have a version that supports clipboard, you will see

+clipboard

If you do not have a version that supports it, you will see

-clipboard

In which case you can fix this by reinstalling vim as vim-gtk

sudo apt-get install vim-gtk

You then need to set in your vim rc that the clipboard should work with your general system clipboard. You can do this by having the following in your vimrc

set clipboard=unnamed

If you open up vim and type the following command you will see the clipboard setting.

set clipboard?

Command Line

Open vim with the first file found from search results

vim $(find . -iname "SomeFile.txt")

Open vim with a tab for each file matching results

vim -p $(find . -iname ".txt")

Window Tabs

Close all tabs but the current

:tabo[nly]

Splitting Windows

Vertical split

:vsp

Set vertical split to the right

:set splitright

Set horizontal split to below

:set splitbelow

alternatively

:botright vnew
