undefined control

Cause

This message, prefaced by the file name and line number involved, is from the C preprocessor /usr/ccs/lib/cpp, and indicates a line starting with a sharp (#) but not followed by a valid keyword such as define or include.

Action

A piece of software might be running the C preprocessor on an initialization file that you thought was interpreted by a shell. In most shells, the sharp (#) indicates a comment. The C preprocessor considers comments to be anything between /* and */ delimiters.
