This option controls the variety of regular expression syntax
understood by the @samp{-regex} and @samp{-iregex} tests. This option
is positional; that is, it only affects regular expressions which
occur later in the command line. If this option is not given, POSIX
basic regular expressions are assumed. Currently-implemented types
occur later in the command line. If this option is not given, GNU
Emacs regular expressions are assumed. Currently-implemented types

Instead of using substring or shell glob matching, the pattern
specified on the command line is understood to be a POSIX extended
regular expression. File names from the @code{locate} database
are matched using the specified regular expression. If
the @samp{-i} flag is also given, matching is case-insensitive.
Matches are performed against the whole path name, and so by default a
pathname will be matched if any part of it matches the specified
regular expression. The regular expression may use @samp{^} or
@samp{$} to anchor a match at the beginning or end of a pathname.
