On Linux, gzip is unable to compress a folder, it used to compress a single file only. To compress a folder, you should use tar + gzip, which is tar -z.
Note
$ tar --help
-z, -j, -J, --lzma Compress archive with gzip/bzip2/xz/lzma
For example,
tar -zcvf outputFileName folderToCompress
1. Tar + Gzip a folder
Example to gzip a folder named “newrelic”, and also all the files within that folder, into a single compressed file newrelic.tar.gz
$ tar -zcvf newrelic.tar.gz newrelic/

Hi. how do we pull a similar stunt using pigz [Parallel Implementation of GZip]
Thank you, some good examples of using tar with gzip here, I also found the extra information on what else can be done with gzip at these locations below, hopefully it helps anyone else seeking more info too.
