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, $orig_uri) = @_; return qq(<a href="$uri">$orig_uri</a>); } my $finder = 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.
