+.TH PCREGREP 1
+.SH NAME
+pcregrep - a grep with Perl-compatible regular expressions.
+.SH SYNOPSIS
+.B pcregrep [-Vcfhilnrsvx] pattern [file] ...
+
+
+.SH DESCRIPTION
+\fBpcregrep\fR 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
+\fBpcre(3)\fR for a full description of syntax and semantics.
+
+If no files are specified, \fBpcregrep\fR 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 \fBpcregrep\fR behaves.
+
+Lines are limited to BUFSIZ characters. BUFSIZ is defined in \fB<stdio.h>\fR.
+The newline character is removed from the end of each line before it is matched
+against the pattern.
+
+
+.SH OPTIONS
+.TP 10
+\fB-V\fR
+Write the version number of the PCRE library being used to the standard error
+stream.
+.TP
+\fB-c\fR
+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.
+.TP
+\fB-f\fIfilename\fR
+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.
+.TP
+\fB-h\fR
+Suppress printing of filenames when searching multiple files.
+.TP
+\fB-i\fR
+Ignore upper/lower case distinctions during comparisons.
+.TP
+\fB-l\fR
+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.
+.TP
+\fB-n\fR
+Precede each line by its line number in the file.
+.TP
+\fB-r\fR
+If any file is a directory, recursively scan the files it contains. Without
+\fB-r\fR a directory is scanned as a normal file.
+.TP
+\fB-s\fR
+Work silently, that is, display nothing except error messages.
+The exit status indicates whether any matches were found.
+.TP
+\fB-v\fR
+Invert the sense of the match, so that lines which do \fInot\fR match the
+pattern are now the ones that are found.
+.TP
+\fB-x\fR
+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.
+
+
+.SH SEE ALSO
+\fBpcre(3)\fR, Perl 5 documentation
+
+
+.SH 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).
