I came across a neat program today called Kaptain. Its premise is simple, but it may be a solution for those who don't like the command line, or have trouble remembering the available switches, but don't know of a good graphical alternative.

Kaptain displays a graphical interface with radio or check boxes for available switches and text boxes for everything else. A brief sampling of the supported programs is listed below.

find
grep
ls
tar
wget
whois

A template script is needed in order for an app to be supported. There are many useful apps included by default, but you can also add your own.
