grep с регулярными выражениями, совместимыми с Perl (a grep with Perl-compatible regular expressions.)
NEWLINES
The -N (--newline) option allows pcregrep to scan files with
different newline conventions from the default. Any parts of the
input files that are written to the standard output are copied
identically, with whatever newline sequences they have in the
input. However, the setting of this option does not affect the
interpretation of files specified by the -f, --exclude-from, or
--include-from options, which are assumed to use the operating
system's standard newline sequence, nor does it affect the way in
which pcregrep writes informational messages to the standard
error and output streams. For these it uses the string "\n" to
indicate newlines, relying on the C I/O library to convert this
to an appropriate sequence.
