I encountered a counterintuitive behavior of 'sort' in modern Linux releases.
I checked the sorting behavior of sort, as installed in Debian Jessie and Ubuntu 14.04 LTS. Turns out that the default behavior of sort (with locale=en_US.UTF-8) is not to sort by ASCII order, but as if letters and digits are more important to sort order than punctuation marks. Attached please find a sort-test.txt file and the output of sort < sort-test.txt (as the file actual.txt). To show how would the output look like using pure ASCII sort, I sorted sort-test.txt using python-sort.py (attached). and got the result reproduced in correct.txt (attached). The problem is then what options would get GNU sort to sort like python-sort.py? Can anyone shed a light on the matter? --- Omer -- No actual electrons, animals or children were harmed by writing this E-mail message.
