How to make Powerline fonts work with iTerm2

You could add something like this to the startup script of your default shell (mine is zsh, most people use bash, I guess, so you may have to tweak.)

Here's my bit of screen jiggery-pokery (in my .zshrc)

# Autoload screen if we aren't in it.  (Thanks Fjord!)
if [[ $STY = '' ]] then screen -xRR; fi

I got this from somewhere on the interwebs (I don't recall where, and I don't know who Fjord is, but good on him.

With this you can close your iTerm window, and it will resume where you left off when you reopen it. I highly recommend reading the screen man page also.

With the \033]0;TEXT\007 escape sequence.

Example of use in Bash: echo -ne "\033]0;$PWD\007"

Which you could add to your $PROMPT_COMMAND if you use Bash, or otherwise attach to you PS1 so it gets re-evaluated often.

Example: export PROMPT_COMMAND='echo -ne "\033]0;$PWD\007"'
