Yes, but I think it's less tricky and unportable to write "mv -f" than "/bin/mv". So even if it _is_ a funny alias thing, I think my patch is the right fix. > One downside of working it around like your patch does, or spelling > it out as "/bin/mv", is that we'd need to worry about all the uses > of "mv" in our scripts.

I would be curious to know whether it is a funny thing in the Travis environment, or if some version of macOS "mv" really is that braindead (and it is just the case that Travis has that version and Lars's computer doesn't). I just didn't want to waste anybody's time digging into it if it won't affect our patch. I guess the way to dig would be to add a test that looks at the output of "type mv" or something, push it to a Travis-hooked branch, and then wait for the output -Peff
