I'm using iTerm 2 nightly and I have the following tmux config setting for the left status bar:set -g status-left #[fg=green]#h @ #[fg=cyan]#(extip | awk '{print \ip \ $1}') #[fg=yellow]#(ifconfig en0 | grep 'inet ' | awk '{print \en0 \ $2}')  #[fg=red]#(ifconfig tun0 | grep 'inet ' | awk '{print \vpn \ $2}'Which is supposed to print my external IP, en0 and, if connected, my vpn connection. extip is my own tool that I wrote myself, but haven't touched in quite some time, and it works great from the command line (and I can see that it gets invoked and returns correctly when attaching a debugger to it). It all worked great until a couple of weeks ago, and since then it just displays <'extip | awk '{print ip  $1}'' not ready> instead of my external IP address. The rest is still working perfectly without any issues. At first I thought it was just iTerm nightly being unstable, but a couple of updates have passed and it still doesn't work, so I'm feeling that maybe it wasn't supposed at all ever and just did by some kind of fluke? Can anyone give me some pointers with regards to why it may have stopped working and how I can get it to work again?
