==name match

==short-description

Print to C<stdout> any lines of C<stdin> that match a particular pattern.

==long-description

Note, does not support regular expressions, only Symbian's descriptor wild characters (aka C<TDesC::Match()>. Since these don't explicitly support anchoring (functionality provided by C<^> and C<$> in regular expressions) if you want to match an word within a line you need to put C<*> characters at either end of the pattern string. If you don't, then the match will be implicitly anchored to either end of the line.

==argument string pattern

The pattern to be matched. Symbian descriptor wild characters supported.

==option bool i ignore-case

Ignore case distinctions.

==option bool v invert-match

Print lines that do B<not> match.

==option bool c count

Don't print the lines that match, just count them and print the total at the end. If used with C<--invert-match>, counts the number of non-matching lines.
