Hi, I think I found a bug in sort from coreutils-9.5 on Gentoo Linux:
$ LANG=C sort -k 1 -k 3,3n -r somefile.tsv | head LH00211:37:222VFLLT1:1:2270:9996:7938:TACGTCACG MN908947.3 97.333 150 4 0 1 150 22850 22999 5.82e-46 171 LH00211:37:222VFLLT1:1:2270:9996:7938:TACGTCACG MN908947.3 96.667 150 5 0 1 150 23133 22984 2.53e-45 169 LH00211:37:222VFLLT1:1:2270:9996:23383:CGGGTCCTC MN908947.3 99.333 150 1 0 1 150 22844 22695 7.14e-48 178 LH00211:37:222VFLLT1:1:2270:9996:23383:CGGGTCCTC MN908947.3 99.286 140 1 0 11 150 22568 22707 2.47e-44 166 LH00211:37:222VFLLT1:1:2270:9996:22101:GAAGGATTC MN908947.3 98.667 150 2 0 1 150 22850 22999 3.10e-47 176 LH00211:37:222VFLLT1:1:2270:9996:22101:GAAGGATTC MN908947.3 97.333 150 4 0 1 150 23133 22984 5.82e-46 171 LH00211:37:222VFLLT1:1:2270:9996:21012:CGTGACGCA MN908947.3 98.000 150 3 0 1 150 23133 22984 1.34e-46 173 LH00211:37:222VFLLT1:1:2270:9996:21012:CGTGACGCA MN908947.3 100.000 150 0 0 1 150 22850 22999 1.65e-48 180 LH00211:37:222VFLLT1:1:2270:9987:8915:CACCGATGT MN908947.3 98.571 140 2 0 11 150 22568 22707 1.07e-43 164 LH00211:37:222VFLLT1:1:2270:9987:8915:CACCGATGT MN908947.3 97.333 150 4 0 1 150 22844 22695 5.82e-46 171 $ The line 8 with value 100.000 should appear one line earlier, on line 7 (the value 100.000 should precede 98.000). I want to sort by first column and then numerically the float values in column 3, highest to lowest. It works for float values below 100. Thank you, Martin
