https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=213128 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 … 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 … 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-“|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 are appended to the end of the sorted strings: echo -e "ab-\nabcdefg&\nabd#\nabcde@\nabc&\nabcdef_"|sort -V abcdefg& abcdef_ abcde@ abc& abd# ab- -- You are receiving this mail because: You are the assignee for the bug.
