https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D213128 Bug ID: 213128 Summary: version sort (sort -V) order incorrect with non-alphanumeric characters Product: Base System Version: 10.3-RELEASE Hardware: i386 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: skh1002@hotmail.com CC: freebsd-i386@FreeBSD.org CC: freebsd-i386@FreeBSD.org On FreeBSD 10.3-RELEASE-p9 with /usr/bin/sort version 2.3-FreeBSD: Version-sorting produces incorrect order if non-alphanumeric characters are present in sorted lines. Prefix (name) parts of the sorted lines sharing the same starting characters are seemingly sorted in the reverse order. This is= an example from my package folder: $ ls /usr/ports/packages/All | sort -V =E2=80=A6 pkgconf-0.9.12_1.txz pkgconf-1.0.1.txz pkg-1.6.4_1.txz pkg-1.7.1.txz pkg-1.7.2.txz =E2=80=A6 To reproduce the behaviour, the following can be done. The next two commands produce identical and correct output: $ echo -e "aa\nab\nabcdefg\nabd\nabcde\nabc\nabcdef"|sort aa ab abc abcde abcdef abcdefg abd And $ echo -e "aa\nab\nabcdefg\nabd\nabcde\nabc\nabcdef"|sort -V aa ab abc abcde abcdef abcdefg abd However, the second of these two produces clearly incorrect sort order: $ echo -e "aa-\nab-\nabcdefg-\nabd-\nabcde-\nabc-\nabcdef-=E2=80=9C|sort aa- ab- abc- abcde- abcdef- abcdefg- abd- But $ echo -e "ab-\nabcdefg-\nabd-\nabcde-\nabc-\nabcdef-"|sort -V abcdefg- abcdef- abcde- abc- abd- ab- The same behaviour is observed when different non-alphanumeric characters a= re appended to the end of the sorted strings: echo -e "ab-\nabcdefg&\nabd#\nabcde@\nabc&\nabcdef_"|sort -V abcdefg& abcdef_ abcde@ abc& abd# ab- --=20 You are receiving this mail because: You are on the CC list for the bug.=
