This is a simple xbar plugin to show hidden dot files (or hide them again) written in shell script, because I needed it... for reasons.
First, this plugin assumes you have xbar, the bitbar reboot.
Assuming this is so, drop showdotfiles.2m.sh in your xbar plugins folder. Be sure to set the file to executables by entering chmod +x showdotfiles.2m.sh on the command line while in the directory where showdotfiles lives.
xbar is a Mac OS app that allows you to put (almost) anything in your Mac's menu bar.
