coreutils-8.25 compiled from source on Fedora 24: % echo "+00\n-0c\n+02\n-02" | src/sort +00 -02 +02 -0c
This seems to be due to locale: % echo "+00\n-0c\n+02\n-02" | LC_ALL=C src/sort +00 +02 -02 -0c echo "+00\n-0c\n+02\n-02" | LC_ALL=en_US.UTF-8 src/sort +00 -02 +02 -0c Since OS X 10.11 still comes with coreutils 5.93, I tried that: % echo "+00\n-0c\n+02\n-02" | LC_ALL=en_US.UTF-8 sort +00 +02 -02 -0c I've taken a look at the Unicode collation standard, and I can't immediately see anything that explains the current (8.25) behavior. I've also played around with < http://demo.icu-project.org/icu-bin/locexp?_=en_US.UTF-8&d_=en&x=col> and I can't come up with any set of Unicode collation options that gives the same results. mathew
