Best Answer
You can obviously not count newlines if the file is still compressed.
But you can decompress to a stream, and count the newlines in that stream, without ever writing the (decompressed) file to disk. That would go something like so:
zcat for decompress & cat, wc for wordcount. See man pages for both if you want to know more.
EDIT
If you do not have zcat, zcat is just another name for
gunzip -c
.
