How can I do that in bash or perl, that I have a txt file, e.g.:

$cat file.txt
Hi, this is the content of the txt file, that contains links like this:
http://www.somewhere.it/, and it could contain: http://somewhere.com,
etc..
This is the second line, that doesn't contains links..
..
This is the XYZ line, that contains a link: http://www.somewhere.net
$


...ok.. so how could I make a regexp for this?

Turning:

http://website.org
http://www.website.org

to this:

<a href=3Dhttp://website.org>http://website.org</a>
<a href=3Dhttp://www.website.org>http://www.website.org</a>

The solution would be:

sed 'SOMEMAGIC' file.txt > file.html
or
perl 'SOMEBIGMAGIC' file.txt > file.html

:D

something like

sed -ie s/(.*)/<a href=3D"\1">\1</a>/ filename

Not sure of the EXACT syntax but that should be close.

(apologies if this gets sent twice, I sent the first from the wrong address)

sed -e 's_\(\bhttp://\S*\)_<a href=3D"\1">\1</a>_g'

Not perfect, as some characters should be urlencoded
inside the href.

Parsing URIs using regular expressions (as others have suggested) is
harder than it looks. I recommend using a Perl module like URI::Find
(which is available as an RPM for Fedora - yum install perl-URI-Find).

The code looks like this (lightly adapted from the module's documentation):

#!/usr/bin/perl

use strict;
use warnings;

use URI::Find;

sub replace {
  my ($uri, $orig_uri) =3D @_;

  return qq(<a href=3D"$uri">$orig_uri</a>);
}

my $finder =3D URI::Find->new(\&replace);

while (<>) {
  $finder->find(\$_);
  print $_;
}

Put that in a file (called, perhaps, urifind) and make that file
executable. You can then run it like this:

./urifind file.txt > file.html

Hope that helps.

Dave...
