Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

What others think

How about this. It only needs one call to sed:

links -dump -no-numbering -no-references http://www.commandlinefu.com/commands/random | sed -e '/Add to favourites/,$d' -e '1,/_____________________/d'

Hi guys, your snippet is not reliable that way. By example with & or spaces, the output is broken. This one is longer as yours but reliable :

perl -MHTML::TreeBuilder -MWWW::Mechanize -e 'my $b = WWW::Mechanize->new( autocheck => 1 ); $b->get("http://www.commandlinefu.com/commands/random"); my $t = HTML::TreeBuilder->new_from_content(\$b->content); for ($t->look_down("_tag", "div", "id", "window-bar")) { print "Description :", $_->as_text, "\n"; } for ($t->look_down("_tag", "div", "class", "line")) { print $_->as_text, "\n"; } $t = $t->delete;'

If I'ill have time to spent, I'll try to make it shorter...

Comment by sputnick 391 weeks and 5 days ago

A little bit shorter :

perl -MHTML::TreeBuilder -MWWW::Mechanize -e 'my $b = WWW::Mechanize->new; $b->get("http://www.commandlinefu.com/commands/random"); my $t = HTML::TreeBuilder->new_from_content(\$b->content); $te = $t->look_down("_tag", "div", "id", "window-bar"); $tl = $t->look_down("_tag", "div", "class", "line"); for ($te, $tl) { print $_->as_text, "\n"; }; $t = $t->delete;'

hi sputnick i get:

Can't locate WWW/Mechanize.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.10.0 /usr/local/share/perl/5.10.0 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .).

BEGIN failed--compilation aborted.

do i need to install something?

Comment by lxtips 391 weeks and 5 days ago

lxtips : run this command as root to auto-install needed perl modules :

# for m in HTML::TreeBuilder WWW::Mechanize; do perl 2>/dev/null -e "use ${m}" || cpan -i ${m}; done
