I suspected it might be perhaps to 'cd' being a built-in, and looking at the source code for "" my suspicion was confirmed. The last line that executes the command is: rc -c $"_x Any reason why this isn't using eval instead so that rc built-ins work (eval $"_x) P.S. There doesn't appear to be any man page for "" or ", and lookman doesn't support "" either: cpu% lookman "" usage: lookman key ... cpu% lookman '""' usage: lookman key ... cpu%
