+@section Exit status
+
+Nearly every command invocation yields an integral @dfn{exit status}
+that can be used to change how other commands work.
+For the vast majority of commands, an exit status of zero indicates
+success, and a value of @samp{1} indicates failure.
+However, some of the programs documented here do produce
+different exit status values and a few associate different
+meanings with the values @samp{0} and @samp{1}.
+Here are some of the exceptions:
+@command{expr}, @command{false}, @command{nohup}, @command{printenv},
+@command{sort}, @command{test}, @command{true}, @command{tty},
+@command{uniq}.
