# dirbysize.pl
# AIM: Read a file output from the DIR command, and order the files in SIZE
# order ... drop out the pure <DIR> entries ...
# 15/09/2011 - Limit file name length to say 32 chars, and exit is no input
# 2010/03/28 - option to omit CVS/svn/git directories
# 2/13/2009 - Add delete (unlink) of log file at end, and skip if <DIR> is 3[2] or 4th[3] entry...
# 20061219 - Can NOT use just $0 to get script name, since when directly invoke from
# a command prompt, it becomes C:\GTools\Perl\dirbydate.pl, so added some regex to
# massage the name, and just get the perl script name ... if a DRIVE included /^\w{1}:\\.*/
# AND, to enable it to FIND the logfile.pl, add unshift(@INC, 'C:/GTools/perl');
# OR this can be use lib '/Users/User/perl-lib';, or perl -MC:/GTools/perl -e dirbydate.pl
# and added a $evenspace option ...
# geoff mclane - 28 March, 2007 - geoffmclane.com - based on dirbydate.pl
