My notes, things I have learned, and documentation I have created.

To display all the special characters or escape sequences:

: set list

To find the tab character (^I). Hold down control and hit vi.:

/^vi

I never seem to remember this. I always forget that it is the 0. I have used this on linux and unix.

find . -type f -mtime 0

How to find more than one name pattern:

find /tmp -name *.abc -o -name *.def -o -name *.ghi -o -name *.jkl -type f -print
