Nice! I just spotted this on twitter (thanks, @climagic). You can ask curl not to do that progress meter with -s.
Today, the alt text has HTML entities in it. You could use Perl to convert those
perl -MHTML::Entities -MLWP::Simple -E 'say decode_entities $+{t} if $_ = get "http://xkcd.com" and /title="(?[^"]+)" alt=/'
Alternatively, you could still use curl for the download
curl -s xkcd.com | perl -MHTML::Entities -nE 'say decode_entities $+{t} if /title="(?[^"]+)" alt=/'
Ack! HTML ate my regular expression. That capture named t is (?<t>...), so
perl -MHTML::Entities -MLWP::Simple -E 'say decode_entities $+{t} if $_ = get "http://xkcd.com" and /title="(?<t>[^"]+)" alt=/'
and
curl -s xkcd.com | perl -MHTML::Entities -nE 'say decode_entities $+{t} if /title="(?<t>[^"]+)" alt=/'
Sorry about that.
