Print-debugging scripts with Growl Written March 1, 2007 at 21:23 GMT. Tagged OS X. Sometimes I find myself writing scripts in contexts where you can’t easily debug just by printing to STDOUT. Rather than messing with a log file that you then have to look for/open (I often touch /tmp/wood), this (suggested by Johan) works if you’ve got Growl with growlnotify. Drop into a shell and: 1 growlnotify -m 'Still executing!'
