comment What constitutes a 'guest' account on Snow Leopard?
OK - it is an 'official' term. That helps a lot - and none of my accounts is a guest account within the meaning of that term.

comment Recursive chmod: rw for files, rwx for directories
Do you really want public write permission on files and directories? That means you don't care who clobbers any of the files?

comment How to install perl5.10 on OS X 10.5.8?
It depends which which you have as /usr/bin/which. The machines I used back in the late 80s didn't have any which in any system bin directory, which was a nuisance. Hence I cribbed this code. I added the -a, -r, -w, -x options relatively recently. If you've got a functional which, you don't need this one; if you don't, it may save you some grief.

comment Where does Mac OS X store file association information?
Yeah, but knowing how to change them also helps. Like it helped for me... @joshhunt: maybe if you made it explicit that the Get Info stuff is in the Finder with the file selected. (Just had to undo one application grabbing another's files - this helped.)

comment How to Suppress Repetition of Warnings That an Application Was Downloaded From the Internet on Mac OS X?
I found another way to get rid of the warning - install the next release of the software as administrator, after downloading it as administrator (Firefox 3.5.3). However, that is a pure evasion of the problem. This command does the trick. However, it does not seem to be well documented - at least, I didn't find a man page for it (but I can STFW and 'xattr -:' gives sufficient info). Thanks!
