Symlinking Dotfiles

I've got a dotfiles folder living in the git dir where I keep my dotfiles for git control purposes.

move the dotfile you want (I'll be referring to my i3 config file): mv ~/.config/i3/config ~/git/dotfiles/config

symlink the dotfile so it can be loaded: ln -s ~/git/dotfiles/config ~/.config/i3/config

I always forget the syntax: ln -s followed by <where the file actually lives> followed by <where I want to file to pretend to live>

Running sed nondestructively first

I want to test my sed string on a file, or many files before doing something wild. sed -n "s/search-term/replacement/p" file-name

I also can do a count on occurances across a directory to compare after the change ag -Q "search-term" | wc -l
