Hello Alain,

I need to perform a sort based on the first 3 indexes of a line (sort -k 1,3 -n

The 0 coordinates are not placed before the 2 coordinates, it looks like the
spaces are ignore:

[alainm@tagir 1src]$ sort -k 1,3 -n truc.lst
To sort multiple numeric fields, use separate "-k" parameters, like so:
sort -k1,1 -k2,2 -k3,3 -n truc.list
If in the future you wish to combine different ordering (e.g. numeric and
alphanumeric, or some fields in reverse order),
consider specifying the order in each key instead of globally:
sort -k1n,1 -k2nr,2 -k3n,3 truc.list
[alainm@tagir 1src]$ sort --version
sort (GNU coreutils) 8.4
If you upgrade to coreutils version 8.6 or later, sort will accept '--debug'
option, which will help you troubleshoot such cases:
$ sort --debug -k 1,3 -n truc.lst
sort: using ‘en_US.UTF-8’ sorting rules
sort: key 1 is numeric and spans multiple fields
[...]
I'm marking this bug as done, but discussion can continue by replying to this
thread.
