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
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.
