Sort log files solution

[Ray Phillips]

I presume the solution provided on this page:

https://www.gnu.org/software/coreutils/manual/html_node/sort-invocation.html#sort-invocation

to the "Sort a set of log files, primarily by IPv4 address and
secondarily by timestamp." problem is for an earlier version of sort,
since (unless I'm mistaken) that can now be done using one command:

usort -s -k1,1V -k4.2,4.3n -k4.5,4.7M -k4.9,4.12n -k4.14,4.15n -k4.17,4.18n -
k4.20,4.21

I tried that on Windows 10 with this sort:

C:\> sort --version
sort (GNU coreutils) 8.26

Perhaps that alternative could be added to the web page?
