It doesn't. But even on Unix I have no guarantee that which will be installed on the system.	[reply]

That exactly. And additionally, "which" might produce considerably different results in a (perl) script than on the command prompt, as some shells have "which" as a builtin or alias, so people think they have which (program) but in fact use the shell functionality. Enjoy, Have FUN! H.Merijn	[reply]

Stackexchange why not use which and what to use instead argues strongly against using the `which` command. BTW, I've always used the `type` command (never `which`) -- see here for why. :)	[reply] [d/l] [select]
