iterm2

1 Introduction

Install iterm2

brew install iterm2

Set out the configuration needs for the terminal

2 Notes on setting up iterm2:

Useful Keyboard shortcuts

cmd + shift + enter -> maximize current window (especially useful when you use split windows)
cmd + t -> open a new tab
cmd + w -> close focused window
cmd + d -> split window vertically
cmd + shift + d -> split window horizontally
cmd + {1..9} -> Move to tab with number {1..9}
cmd + i -> change name of the tab

Set up the status bar for time, git, directory. This reduces the burden on the shell prompt.

settings/profiles/session/

check “status bar enabled” at bottom of screen

In interactive screen drag “current directory”, “Empty space”, and “git state” into Active components section.

settings/appearance

“Status Bar location” select “Bottom”

or alternatively

cd ~

ln -s ~/Dropbox/dotfiles/iterm2Profiles.json .

in iterm2 profiles/Other Actions/Import JSON profiles iterm2Profiles.json

Set out the configuration needs for the shell

Good place to start:
