I would say offered in that format, a request to use google makes even my last reply irrelevant. Now if only everyone who said "use google" gave relevant search terms or clues we would be set.

Edit:
Agreed about the availability of such apps as default, but on N900, only one of them is available via extras (wget). I was just trying to think of commands I use more frequently. As for locate vs find, while I can appreciate that find can do the same thing and a lot more (heck, IIRC find is called from within locate), I am lazy.

As for what a regular user uses, I was thinking about the part of the discussion that was directing users to use google for linux commands.
