pcregrep




SYNOPSIS

       pcregrep [-Vcfhilnrsuvx] [long options]  [pattern]  [file1
       file2 ...]


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
       pcrepattern for a full description of syntax and semantics
       of the regular expressions that PCRE supports.

       A pattern must be specified on the command line unless the
       -f option is used (see below).

       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
                 otherwise have been printed.  If  several  files
                 are  given, a count is printed for each of them.

       -ffilename
                 Read a number of patterns from the file, one per
                 line, and match all of them against each line of
                 input. A line is output if any of  the  patterns
                 match  it.  When -f is used, no pattern is taken
                 from the command line; all arguments are treated
                 as  file  names.  There is a maximum of 100 pat­
                 terns. Trailing  white  space  is  removed,  and
                 blank  lines are ignored. An empty file contains
                 no patterns and therefore matches nothing.

       -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.

       -u        Operate in UTF-8 mode. This option is  available
                 only  if  PCRE has been compiled with UTF-8 sup­
                 port. Both the pattern and each subject line are
                 assumed to be valid strings of UTF-8 characters.

       -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.


LONG OPTIONS


       Long  forms  of  all  the options are available, as in GNU
       grep. They are shown in the following table:

         -c   --count
         -h   --no-filename
         -i   --ignore-case
         -l   --files-with-matches
         -n   --line-number
         -r   --recursive
         -s   --no-messages
         -u   --utf-8
         -V   --version
         -v   --invert-match
         -x   --line-regex
         -x   --line-regexp

       In addition, --file=filename is equivalent to  -ffilename,
       and --help shows the list of options and then exits.


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).
                                                      PCREGREP(1)
