Are you a hack programmer? Do you find yourself constantly Googling for how to do basic programing tasks?

Suppose you want to know how to format a date in bash. Why open your browser and read through blogs when you can just…

$ howdoi format string bash
> [foo@bar ~]$date --date "2012-02-13" +%s
> 1329055200
> [foo@bar ~]$date --date @1329055200
> Mon Feb 13 00:00:00 EST 2012
> [foo@bar ~]$date --date @1329055200 +"%Y-%m-%d"
> 2012-02-13

howdoi will answer all sorts of queries
