Thank you for your post. That is quite there but not enough. See, I have
these directories and files in my C:\Perl\ folder
Volume in drive C has no label.
Volume Serial Number is 248A-0894
Directory of C:\Perl
04.03.2009 19:18 <DIR> .
04.03.2009 19:18 <DIR> ..
03.03.2009 21:41 <DIR> bin
03.03.2009 21:24 <DIR> cpan
03.03.2009 21:40 <DIR> eg
03.03.2009 21:42 <DIR> etc
03.03.2009 21:41 <DIR> html
03.03.2009 21:41 <DIR> lib
03.03.2009 21:40 <DIR> man
03.03.2009 20:23 <DIR> OmatPerlit
03.03.2009 22:09 225 Print_directory_sizes.pl
01.10.2008 18:00 <DIR> site
04.03.2009 19:18 0 text.txt
2 File(s) 225 bytes
11 Dir(s) 28ÿ409ÿ733ÿ120 bytes free
And I would like to write to script which prints into STDOUT (=cmd screen)
all the directories in this folder (C:\Perl\) and and their size. So the out
put should look like this:
Directory bin: size xxx megabytes
Directory cpan: size xxx megabytes
Directory eg: size xxx megabytes
Directory etc: size xxx megabytes
...and so on
Even better, if I could print out all the subdirectories also.
