Agreed.

I was following the style of the original code sample.

For simple file naming, you are quite correct. 'Sort' as used here is, indeed, pointless.

However, if my files were foolishly named something like

   foo_xxxxxxx_1.gz
   foo_xxxxxxx_2.gz
   foo_xxxxxxx_3.gz
   foo_xxxxxxx_4.gz
   foo_xxxxxxx_5.gz
   foo_xxxxxxx_6.gz
   foo_xxxxxxx_7.gz
   foo_xxxxxxx_8.gz
   foo_xxxxxxx_9.gz
   foo_xxxxxxx_10.gz
   foo_xxxxxxx_11.gz
   foo_xxxxxxx_12.gz

then most simple uses of 'sort' (including file globbing) will cause file numbers 10, 11, and 12 to
sort prior to file number 2. "Sufficiently clever" use of 'ls' and 'sort' could overcome this, although
my preference would be to simply rename the files...
