For a lot of Mac users some of the best customisation tips come in the form of simple Terminal commands, but keeping track of all of those can be a bit difficult. To help manage all these Terminal hacks GitHub user Mathias Bynens created a list of the 65 best Terminal commands.
Terminal is one of the easiest ways to disable (or enable) hidden features on a Mac. If you find a feature you want to enable on the list, open up Terminal, type in the code, and you're good to go. The list is full of handy tips for removing annoying animations in Mail, customising the dock behaviour and plenty more. One command we haven't seen before removes the green checkmark from Dropbox files in Finder:
file=/Applications/Dropbox.app/Contents/Resources/check.icns [ -e "$file" ] && mv -f "$file" "$file.bak" unset file
Hit up the list on GitHub for a whole slew of other handy Terminal commands to help you customise OS X in a number of ways. Most of the items on the list are for OS X Lion, but a few work on older operating systems as well.
