+NAME
+     pcregrep - a grep with Perl-compatible regular expressions.
+
+
+
+SYNOPSIS
+     pcregrep [-Vcfhilnrsvx] pattern [file] ...
+
+
+
+DESCRIPTION
+     pcregrep searches files for character patterns, in the  same
+     way  as other grep commands do, but it uses the PCRE regular
+     expression library to support patterns that  are  compatible
+     with  the  regular  expressions of Perl 5. See pcre(3) for a
+     full description of syntax and semantics.
+
+     If no files  are  specified,  pcregrep  reads  the  standard
+     input.  By  default,  each  line that matches the pattern is
+     copied to the standard output, and if there is more than one
+     file,  the  file name is printed before each line of output.
+     However, there are options  that  can  change  how  pcregrep
+     behaves.
+
+     Lines are limited to BUFSIZ characters. BUFSIZ is defined in
+     <stdio.h>.  The newline character is removed from the end of
+     each line before it is matched against the pattern.
+
+
+
+OPTIONS
+     -V        Write the version number of the PCRE library being
+               used to the standard error stream.
+
+     -c        Do not print individual lines; instead just  print
+               a  count  of the number of lines that would other-
+               wise have  been  printed.  If  several  files  are
+               given, a count is printed for each of them.
+
+     -ffilename
+               Read patterns from the file,  one  per  line,  and
+               match  all  patterns against each line. There is a
+               maximum of 100 patterns. Trailing white  space  is
+               removed,  and  blank  lines  are ignored. An empty
+               file contains no patterns  and  therefore  matches
+               nothing.
+
+     -h        Suppress printing of filenames when searching mul-
+               tiple files.
+
+     -i        Ignore upper/lower case distinctions  during  com-
+               parisons.
+
+     -l        Instead of printing lines  from  the  files,  just
+
+               print the names of the files containing lines that
+               would have been printed. Each file name is printed
+               once, on a separate line.
+
+     -n        Precede each line by its line number in the file.
+
+     -r        If any file is a directory, recursively  scan  the
+               files  it  contains.  Without  -r  a  directory is
+               scanned as a normal file.
+
+     -s        Work silently, that  is,  display  nothing  except
+               error messages.  The exit status indicates whether
+               any matches were found.
+
+     -v        Invert the sense of the match, so that lines which
+               do not match the pattern are now the ones that are
+               found.
+
+     -x        Force the pattern to be anchored  (it  must  start
+               matching  at  the  beginning  of  the line) and in
+               addition, require it to  match  the  entire  line.
+               This is equivalent to having ^ and $ characters at
+               the start and end of each  alternative  branch  in
+               the regular expression.

+
+
+DIAGNOSTICS
+     Exit status is 0 if any matches were found, 1 if no  matches
+     were  found,  and  2  for syntax errors or inacessible files
+     (even if matches were found).
