What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.


If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

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...

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 281 weeks 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
