How do I get the ruby command to point to my 1.9.1 installation, which is located in...

I'm writing a tiny script that calls the "PNGOUT" util on a few hundred PNG files. I simply did this: find $BASEDIR -iname "*png" -exec pngout {} \; And then I looked at my CPU monitor and noticed only one of the core was used, which is quite sad. In this day and age of dual, quad, octo and hexa (?) cores desktop, how do I simply pa...

Sometimes I edit a file that represents a server restart. I would like to "bind" this restart to my vim session, so, after saving a file, it would call a bash script that would restart for me.
