+Normally, the exit status is 0 if selected lines are found and 1 otherwise.
+But the exit status is 2 if an error occurred, unless the <samp><span
class="option">-q</span></samp> or
+<samp><span class="option">--quiet</span></samp> or <samp><span
class="option">--silent</span></samp> option is used and a selected line
+is found.
+Note, however, that <span class="sc">posix</span> only mandates,
+for programs such as <samp><span class="command">grep</span></samp>,
<samp><span class="command">cmp</span></samp>, and <samp><span
class="command">diff</span></samp>,
+that the exit status in case of error be greater than 1;
+it is therefore advisable, for the sake of portability,
+to use logic that tests for this general condition
+instead of strict equality with 2.
