Much depends on which distro you are using, but all explained where

That is clearly not a "why".

Try it and see.

I have no idea what is...

Since I do not know what you are trying to do, I have no idea if
that does it.  But it does appear you are just over-writing the

I suggest that you learn by doing.

I do not see it doing anything useful.

Non-timestamped data is useless.  You want to merge the different

That is in the man page example.  I'm not here to read you the man page.

gpscsv is new, so not much about it on the inner tubes yet.

This is UNIX, many ways to skin the cat.

You'll just blow up Excel.
