command completion notification

["William G. Scott" <wgscott@ucsc.edu>]

Forgive me, as it has been a few years since my last email…

In OS X, 10.8 (aka Mtn Lion), Apple has introduced a notification system.  Using gem, I installed a command-line utility called terminal-notifier.

I wrote a simple function to test its capabilities:

function tnot { "$@" && terminal-notifier -message "$( echo $@ ) returned $?" -title "Command $HISTCMD Completed" >|/dev/null }

Now if I issue a command like

tnot  sleep 12

It will post a notification on the screen and log the notification to the so-called notification center where all the nagging notices pile up.

This isn't particularly elegant.  I would rather use this as a preexec function, or something similar, so I wouldn't have to explicitly type "tnot".  However, there are only a small subset of commands I would want to bind to a notification.

Is it straightforward to somehow bind this to, say, control-return, or some other modified return key sequence?

Thanks.
