Properly compressing KML file in Linux OS

Question

I am trying to compress a KML file using gzip on a Linux system

gzip -cvf somefile.kml > somefile.kmz

When I go to try and verify the new KMZ file in Google Earth, I receive the following error:

Open of file "somefile.kmz" failed: Parse error at line 1, column 0: not well-formed (invalid token)

What happened?

Answer 1

Shout-out to @Vince for the help:

Terminal Code

zip -9 somefile.zip somefile.kml
mv -f somefile.zip somefile.kmz

-9 is for best zip compression

This process can also be optimized by running:

zip -9 somefile.kmz somefile.kml
