Re: Check for another program availability

Second IPC::Run can_run(), which is in core.

But if you really want to iterate over PATH, core module File::Spec has a path() that returns the components of PATH or the OS equivalent. It handles Windows (split on /;/<code> not <code>/:/) and I believe even VMS (SYS$PATH or something similar, not PATH).

IPC::Run isn't core, and does not have a `can_run` method. I think you've confused this with IPC::Cmd which is, and does.	[reply] [d/l]
