Hi bakunin,
No. When no units are specified, such as with -size 2, it is looking for a file that has a size that fits in 2 512-byte blocks which corresponds to a file with a file size that is 513 through 1024 bytes. But when units are specified, an unsigned number is looking for a file with the exact size specified (at least with a BSD-based find utility which is also used on macOS systems). Note that the POSIX standard's find utility's -size primary does not include a units modifier except c (which specifies that the number is counting bytes instead of 512-byte blocks); it just has negative numbers (meaning less than number), unsigned numbers (meaning exactly that number), and positive numbers (with a leading + meaning more than number).

If some other system's find utility treats unit modifiers as block size multipliers instead of just numbers of bytes, that difference in behavior from BSD might be a reason why POSIX hasn't standardized modifiers other than c.

Hi bodisha,
What operating system are you using?

pod::abstract::filter::find

Pod::Abstract::Filter::find(3pm)			User Contributed Perl Documentation			  Pod::Abstract::Filter::find(3pm)

NAME

       Pod::Abstract::Filter::find - paf command to find specific nodes that contain a string.

DESCRIPTION

       The intention of this filter is to allow a reduction of large Pod documents to find a specific function or method. You call "paf find
       -f=function YourModule", and you get a small subset of nodes matching "function".

       For this to work, there has to be some assumptions about Pod structure. I am presuming that find is not useful if it returns anything
       higher than a head2, so as long as your module wraps function doco in a head2, head3, head4 or list item, we're fine. If you use head1 then
       it won't be useful.

       In order to be useful as an end user tool, head1 nodes (...) are added between the found nodes. This stops perldoc from dying with no
       documentation. These can be easily stripped using: "$pa->select('/head1')", then hoist and detach, or reparent to other Node types.

       A good example of this working as intended is:

	paf find select Pod::Abstract::Node
