SO on how to use quickfix for searching and replacing

Update all helptags :Helptags

Sometimes when copying and pasting in text from windows / docx or whatever you get hex chars which aren't utf-8. If you want to do a search and replace you can

  1. Find the hex code by putting your cursor on the character and pressing ga
  2. Then use a search/replace string as normal but specifying hex. E.G :%s/\%xNN//g

Tab/:\zs will line up css nicely on a block

search and replace from within Vim (possibly useful with vim-abolish)

:args `grep -lR string_to_find dirs_to_search`
:argdo %s/string_to_find/replace_with_this/g
:argdo update

String replace over newlines (useful for wordpress picture insertion)
:%s/<\/a>\n{-}<a href/g

execute a vim script over files

Say you have a file with the word "change" in it, and you want to change it to "wibble". And further say there are a few of these files in various sub directories.

Create a bash script like this:

#!/bin/bash

for file in `find . -name *.txt`; do
    vim -e -s $file < wibble.vim
done;

and create the wibble.vim script above which contains the Ex commands required:

%s/change/garble/ge
write
quit

Then you simply run the script, and the Ex commands will be run over all of the files found in the find.

Now, it's easier to simply use the args command above, for this simple search and replace, however, if you have more commands to do, this might be a decent way to do it.

I had issues trying to do this using find & xargs, it's to do with stdin which I really should open a StackOverflow about.

Commands I'm trying to learn

# for when your vim is going really really slowly and you reckon
# it might be to do with syntax.
