Синопсис (Synopsis)

pcretest [options] [input file [output file]]

       pcretest was written as a test program for the PCRE regular
       expression library itself, but it can also be used for
       experimenting with regular expressions. This document describes
       the features of the test program; for details of the regular
       expressions themselves, see the pcrepattern documentation. For
       details of the PCRE library function calls and their options, see
       the pcreapi , pcre16 and pcre32 documentation.

       The input for pcretest is a sequence of regular expression
       patterns and strings to be matched, as described below. The
       output shows the result of each match. Options on the command
       line and the patterns control PCRE options and exactly what is
       output.

       As PCRE has evolved, it has acquired many different features, and
       as a result, pcretest now has rather a lot of obscure options for
       testing every possible feature. Some of these options are
       specifically designed for use in conjunction with the test script
       and data files that are distributed as part of PCRE, and are
       unlikely to be of use otherwise. They are all documented here,
       but without much justification.
