Re: what is /usr/bin/head

And the connection to Perl libwww is that that has a HEAD utility that will conflict on a non-case-sensitive filesystem. The lower-cased head is a unix utility; in the GNU utilities, it is part of coreutils.

Thank you for making it clearer. Is it correct to say that every unix utility must have unique name?	[reply]

If they are all going to live in the same directory, yes. HEAD (and GET and POST) are optional extras in libwww-perl; they are just aliases to the lwp-response script and aren't even built by default. head, on the other hand, is a fairly basic utility that should always be around, and all kinds of shell scripts can be expected to break if it isn't.
