Vim note and shortcuts

windows in Vim

To change the window you want to either be at the far left or top after changing the windows. Do this with ctrl-W t or ctrl-arrow.

Horizontal: ctrl-W H Vertical: ctrl-W K

file format conversion

This link from the vim wiki is pretty comprehensive.

finding CR and newline

In the syntax, s/search/replace/, in the search context \n is newline and \r is carriage return (ctrl-V M, which produces ^M), but in the replace context \n is the null byte and \r is a new line depending on what vim thinks your new line character is, which is set like this :set ffs=unix.

Replace `^M`

See this link for an explaination.

Press and hold ctrl then v then m to get the ^M. Here, the ctrl-v is a special key to write special characters or digraphs. See vim manual.

do things on multiple files

Commands to use with multiple buffers:

arg
argadd
argdel
arglist
argdo
bufdo
windo

Scenario 1 - here you’d get all of the errors for files without matches:

argdo %s/search/replace/gc

Scenario 2 - use e to ignore errors and update to write any buffers that were changes:

argdo %s/search/replace/ge | update
