Nope. tg@caas:~ $ echo foo >'a b' tg@caas:~ $ ^D Connection to caas[…] closed. $ ssh caas cat \'a \ b\' foo Nothing special about explicit space vs. implicit space by argument separator here. On the recipient side, the entire argument vector is just space-joined into one string then passed to the (remote)local shell. Where the space comes from is irrelevant. >> has the effect you want; the first backslash is eaten by the >> local shell. > >Perhaps that depends on the local shell. Yes, I had a different one in mind with this, see the other mail. POSIX does guarantee this (even though it still “feels wrong” to me). >That wasn't one of my examples.

That’s what .Sx does, though such an explicit reference is only appropriate in the most dire cases.
