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

Grep by paragraph instead of by line.

Terminal - Grep by paragraph instead of by line.
grepp() { [ $# -eq 1 ] && perl -00ne "print if /$1/i" || perl -00ne "print if /$1/i" < "$2";}

Grep by paragraph instead of by line.

This is a command that I find myself using all the time. It works like regular grep, but returns the paragraph containing the search pattern instead of just the line. It operates on files or standard input.

grepp <PATTERN> <FILE>




There are 3 alternatives - vote for the best!

What others think

Very nice, but can you think of a smart way to highlight the match, too?

Something like this should operate the similar to "grep --color=auto":

grepp() { [ $# -eq 1 ] && perl -00ne 'if ( /'$1'/i ){my $s = $_;$s =~ s/'$1'/\033[1;31m$&\033[0m/g; print $s}' || perl -00ne 'if ( /'$1'/i ){my $s = $_;$s =~ s/'$1'/\033[1;31m$&\033[0m/g; print $s}' < "$2";}

P.S. @Perl gurus: Suggestions or corrections are very welcome.

I just discovered that it fails if there are spaces in the regex. Quoting the regex fixes it:

grepp() { [ $# -eq 1 ] && perl -00ne 'if ( /'"$1"'/i ){$s = $_;$s =~ s/'"$1"'/\033[1;31m$&\033[0m/g; print $s}' || perl -00ne 'if ( /'"$1"'/i ){$s = $_;$s =~ s/'"$1"'/\033[1;31m$&\033[0m/g; print $s}' < "$2";}
