B.1 Option Syntax

The syntax of the cc command is:

% cc [options] filenames [libraries]...


Use the option -YP, dir to change the default directories used for finding libraries. dir is a colon-separated path list. The default library search order can be seen by using the -### or -xdryrun option and examining the -Y option of the ld invocation.

cc uses getopt to parse command-line options. Options are treated as a single letter or a single letter followed by an argument. See thegetopt(3c) man page.
