Hello, I'm wondering if this is a bug (where "-f" is ignored when using version sort):
========= $ sort --debug -f -k2,2V sort: using simple byte comparison sort: leading blanks are significant in key 1; consider also specifying `b' sort: option `-f' is ignored ========== My assumption is that using "-f" as stand alone parameter should have the same effect as using it in a specific key (for that key). e.g. the following two commands are equivalent: sort -f -k1,1 sort -k1f,1 But the following two commands are not equivalent (because the standalone "-f" is ignored): sort -f -k1V,1 sort -k1Vf,1 Example: ================= ## This works $ printf "a\nB\nc\n" | sort -k1f,1 a B c $ printf "a\nB\nc\n" | sort -f -k1,1 a B c ## This doesn't work $ printf "a13\nA5\na1\n" | sort -k1Vf,1 a1 A5 a13 $ printf "a13\nA5\na1\n" | sort -f -k1V,1 A5 a1 a13 =================== I'm using coreutils 8.10. -gordon
