Hmm, bizarre. =-\ This example works on my machine, and I don't see off-hand what would be preventing it for you: root@viper:/usr/src/usr.bin/diff# diff -U999 /usr/include/sha256.h /usr/include/sha512.h --- /usr/include/sha256.h 2020-04-22 21:38:54.000000000 -0500 +++ /usr/include/sha512.h 2020-04-22 21:38:54.000000000 -0500 @@ -1,99 +1,99 @@ /*- * Copyright 2005 Colin Percival * All rights reserved. * [... omitted ...] root@viper:/usr/src/usr.bin/diff# strings /usr/bin/diff | grep 'conflicting' error: conflicting output format options.
