I would expect that the -g flag tells sort to treat the fields as floating point numbers, but:
cat << EOF | sort -g -k1,2
0 0
0 1.0
0 .5
0 5.0
EOF
gives
0 0
0 1.0
0 .5
0 5.0
Therefore the .5 is not treated as a 0.5. Is this a known bug or what?
p.s.: I’m not asking for a workaround, I have already solved with sed
