System: NetBSD henery 3.0_STABLE NetBSD 3.0_STABLE (HENERY) #34: Mon Jul 24 19:54:43 CEST 2006 src@henery:/usr/obj/home/src/sys/arch/i386/compile/HENERY i386
Architecture: i386
Machine: i386
>Description:
NetBSD's command /usr/bin/which only searches for command names in the
command search path, showing the absolute path to the executable.

Every other system has a slightly different semantic and searches for
a command and reports the absolute path to the executable that would
have been used when the command had been passed to a shell.

The difference is that there a command given with its absolute 
path is found while it isn't with NetBSD's which.

Our csh builtin 'which' on the other hand is compatible.

>How-To-Repeat:

% which man
/usr/bin/man
% which /usr/bin/man
/usr/bin/man
% which nonexistent
nonexistent: Command not found.
% which /usr/bin/nonexistent
/usr/bin/nonexistent: Command not found.

% /usr/bin/which man
/usr/bin/man
% /usr/bin/which /usr/bin/man
% /usr/bin/which nonexistent
% /usr/bin/which /usr/bin/nonexistent
