This is the first unix system I've been on that doesn't have the standard 'head' command to view the top of a file. Instead, the head command on OS X does an HTTP head request. Is there some other head-like binary, or do I need to roll my own?
head is in /usr/bin and works just fine for me. Did you happen to install lwp for Perl and it installed HEAD in /usr/bin? If so, and your filesystem is HFS+, it may have overwritten the original, since HFS+ doesn't allow two files with same names differing only in case.
