Well, it was added after I had posted the original article. The
latest one's find.1 mentions it.
.It Fl E
Interpret regular expressions followed by
options as extended (modern) regular expressions rather than basic
regular expressions (BRE's). The
.Xr re_format 7
manual page fully describes both formats.
As for the syntax my examples conform to, I think they are valid both
for basic and extended.
True if the whole path of the file matches
using regular expression. To match a file named ``./foo/xyzzy'', you
can use the regular expression ``.*/[xyz]*'' or ``.*/foo/.*'', but not
``xyzzy'' or ``/foo/''.
Thanks for your suggestions.
