urifind \- find URIs in a document and dump them to STDOUT.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&    $ urifind file
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fIurifind\fR is a simple script that finds URIs in one or more files
(using \f(CW\*(C`URI::Find\*(C'\fR), and outputs them to to \s-1STDOUT.\s0  That's it.
.PP
To find all the URIs in \fIfile1\fR, use:
.PP
.Vb 1
\&    $ urifind file1
.Ve
.PP
To find the URIs in multiple files, simply list them as arguments:
.PP
.Vb 1
\&    $ urifind file1 file2 file3
.Ve
.PP
\&\fIurifind\fR will read from \f(CW\*(C`STDIN\*(C'\fR if no files are given or if a
filename of \f(CW\*(C`\-\*(C'\fR is specified:
.PP
.Vb 1
\&    $ wget http://www.boston.com/ \-O \- | urifind
.Ve
.PP
When multiple files are listed, \fIurifind\fR prefixes each found \s-1URI\s0
with the file from which it came:
.PP
.Vb 3
\&    $ urifind file1 file2
\&    file1: http://www.boston.com/index.html
\&    file2: http://use.perl.org/
.Ve
.PP
This can be turned on for single files with the \f(CW\*(C`\-p\*(C'\fR (\*(L"prefix\*(R") switch:
.PP
.Vb 2
\&    $urifind \-p file3
\&    file1: http://fsck.com/rt/
.Ve
.PP
It can also be turned off for multiple files with the \f(CW\*(C`\-n\*(C'\fR (\*(L"no
prefix\*(R") switch:
.PP
.Vb 3
\&    $ urifind \-n file1 file2
\&    http://www.boston.com/index.html
\&    http://use.perl.org/
.Ve
.PP
By default, URIs will be displayed in the order found; to sort them
ascii-betically, use the \f(CW\*(C`\-s\*(C'\fR (\*(L"sort\*(R") option.  To reverse sort them,
use the \f(CW\*(C`\-r\*(C'\fR (\*(L"reverse\*(R") flag (\f(CW\*(C`\-r\*(C'\fR implies \f(CW\*(C`\-s\*(C'\fR).
.PP
.Vb 4
\&    $ urifind \-s file1 file2
\&    http://use.perl.org/
\&    http://www.boston.com/index.html
\&    mailto:webmaster@boston.com
\&
\&    $ urifind \-r file1 file2
\&    mailto:webmaster@boston.com
\&    http://www.boston.com/index.html
\&    http://use.perl.org/
.Ve
.PP
Finally, \fIurifind\fR supports limiting the returned URIs by scheme or
by arbitrary pattern, using the \f(CW\*(C`\-S\*(C'\fR option (for schemes) and the
\&\f(CW\*(C`\-P\*(C'\fR option.  Both \f(CW\*(C`\-S\*(C'\fR and \f(CW\*(C`\-P\*(C'\fR can be specified multiple times:
.PP
.Vb 2
\&    $ urifind \-S mailto file1
\&    mailto:webmaster@boston.com
\&
\&    $ urifind \-S mailto \-S http file1
\&    mailto:webmaster@boston.com
\&    http://www.boston.com/index.html
.Ve
.PP
\&\f(CW\*(C`\-P\*(C'\fR takes an arbitrary Perl regex.  It might need to be protected
from the shell:
.PP
.Vb 2
\&    $ urifind \-P \*(Aqs?html?\*(Aq file1
\&    http://www.boston.com/index.html
\&
\&    $ urifind \-P \*(Aq\e.org\eb\*(Aq \-S http file4
\&    http://www.gnu.org/software/wget/wget.html
.Ve
.PP
Add a \f(CW\*(C`\-d\*(C'\fR to have \fIurifind\fR dump the refexen generated from \f(CW\*(C`\-S\*(C'\fR
and \f(CW\*(C`\-P\*(C'\fR to \f(CW\*(C`STDERR\*(C'\fR.  \f(CW\*(C`\-D\*(C'\fR does the same but exits immediately:
.PP
.Vb 3
\&    $ urifind \-P \*(Aq\e.org\eb\*(Aq \-S http \-D 
\&    $scheme = \*(Aq^(\ebhttp\eb):\*(Aq
\&    @pats = (\*(Aq^(\ebhttp\eb):\*(Aq, \*(Aq\e.org\eb\*(Aq)
.Ve
.PP
To remove duplicates from the results, use the \f(CW\*(C`\-u\*(C'\fR (\*(L"unique\*(R")
switch.
