OSX Shell Tips

Key Repeat Rate

Add days to your lifespan by Increasing the key repeat rate. Run the following in the terminal then restart. Protip by Michael Musson.

defaults write -g InitialKeyRepeat -int 13 # normal minimum is 15 (225 ms)
defaults write -g KeyRepeat -int 1 # normal minimum is 2 (30 ms)

A better way to search text: ack

Install ack:

brew install ack

Search files for text, super fast and returns results in a very nice way. By default will search recursively from the current directory and it skips unimportant files by default.

ack "search string"

My .zshrc file

Stored at ~/.zshrc

I used to have ohmyzsh but it made my shell too slow. This is good enough for me.
