I'm Andy Lester, and I like to test stuff. I also write for the Perl Journal, and do tech edits on books. Sometimes I write code, too.

Command line table dumping

[ #21593 ]
Data::Hash::Totals makes it easy for you to do pretty command-line dumping of data, as below:

grep "does not exist" ~/error_log | perl -MData::Hash::Totals -a -F -n -e'++$X{$F[-1]}; END {print as_table(\%X)}'
106 /site/tw/help/images/backgrounds/container.gif
  68 /site/tw/graphics//links/close_window.gif
  53 /site/tw/bk/map2.html
  47 /site/tw/grpahics/links/close_window.gif
  21 /site/tw/bk/map3.html
  15 /site/tw/lgcover.
...

Note that it requires the latest D:H:T, version 0.02 to work. Good thing I'm uploading that right now.

Addendum: You can leave grep out of it, of course:

perl -MData::Hash::Totals -a -F -n -e'++$X{$F[-1]} if /does not exist/; END {print as_table(\%X)}' ~/error_log
