I had to use a different stat command on my Linux system.  This worked for me:<p>find . -type f -exec stat -c %s {} \; | cut -c 1 | sort | uniq -c<p>Note that I exclude directories to avoid the size 4096 bias.<p>I ran it in my "project" directory and found that 38% of my file sizes begin with "1".  That directory includes Perl source code files, input data files, and automatically generated output files.<p>After the digit "1" the distributions ranged from 3% to 9% with no obvious bias I could see.
