App::dategrep dategrep searches the named input files for lines matching a date range and prints them to stdout. If dategrep works on a seekable file, it can do a binary search to find the first and last line to print pretty efficiently. dategrep can also read from stdin and compressed files, but it has to parse every single line until the end of the range for those. INSTALLATION It is possible to install this script via perl normal install routines. perl Build.PL ./Build ./Build install Or you can use one of the two prebuild versions, which already include all or same of dategreps dependencies. Which to choose mainly depends on how hard it is for you to install Date::Manip. The L is just 22.3KB big and includes all libraries except Date::Manip. The L packs everything in a nice, neat package for you, but will cost you almost 10MB of disk space. So, to install the big version you could just type: wget https://mdom.github.io/dategrep/dategrep-standalone-big.pl cp dategrep-standalone-big.pl ~/bin/dategrep chmod +x ~/bin/dategrep And for the small one (with the apt-get for Debian): wget https://mdom.github.io/dategrep/dategrep-standalone-small.pl cp dategrep-standalone-small.pl ~/bin/dategrep chmod +x ~/bin/dategrep apt-get install libdate-manip-perl SUPPORT AND DOCUMENTATION After installing, you can find documentation for this module with the perldoc command. perldoc Foo You can also look for information at: Github Issues https://github.com/mdom/dategrep/issues AnnoCPAN, Annotated CPAN documentation http://annocpan.org/dist/App-dategrep CPAN Ratings http://cpanratings.perl.org/dist/App-dategrep Search CPAN http://search.cpan.org/dist/App.dategrep LICENSE AND COPYRIGHT Copyright 2014 Mario Domgoergen This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
