  • search google on os x

    Searches Google, but requires no "", and will also search all terms input in the CL, eg: > google foo bar returns search URL " You could also use awk to replace all spaces with a +, which is how the Google search handles spaces, but that makes it more than one line.

    function google () { st="$@"; open "http://www.google.com/search?q=${st}"; }

  • Get the Nth argument of the last command in $HISTFILE

    This gets the Nth argument in the last line of your history file. This is useful where history is being written after each command, and you want to use arguments from the previous command in the current command, such as when doing copies/moving directories etc. I wrote this after getting irritated with having to continually type in long paths/arguments. You could also use $_ if all you want is the last argument. Show Sample Output

    function garg () { tail -n 1 ${HISTFILE} | awk "{ print \$$1 }" }
