That is how *diff* behaves, i.e. $ diff foo bar | /usr/bin/diff -u /usr/bin/diff: missing operand after `-u' /usr/bin/diff: Try `/usr/bin/diff --help' for more information. colordiff behaves like diff most of the time and is inheriting diff's behaviour in this case. You can't usually pipe stuff to *diff* in that way: the fact that you can normally pipe diff-like output to colordiff (without parameters) is a deliberate feature of *colordiff*. Are you perhaps suggesting that it should detect the extra parameter '-u' and ignore it when working as a pipe?
