I use this nifty trick in OSX to copy the working directory of one term window to the others.
In the working term window:
pwd | pbcopy
In the term windows you wish to change the directory to the targeted working directory:
Note that this will only work if you don't copy something into OSX's clipboard before pasting.
To make life simpler for myself, I aliased these commands.
alias cpwd='pwd | pbcopy' alias ppwd='cd `pbpaste`'
You must use single quotes if you alias these commands; double quotes will cause the inline execution to execute when the command is being aliased.
