GNU parallel + gunzip (or 7z, or bsdtar, or unzip): extract every "archivename.zip" into (to-be-created) its "archivename" subfolder

Question

As in title. I've got a lot of ZIP archives that I want to extract.

All archives have their own unique name.

All archives contain files only (inside archives there are NOT folder(s) at all: no parent / main folder).

I'd like to process all these ZIP archives via GNU parallel.

To sum up:

• archivename(s).zip has NOT folder(s) inside
• extract content of archivename(s).zip into archivename(s)/ folder (this folder needs to be created!)
• keep archivename(s).zip after extracting it
• repeat this for all the ZIP archivename(s).zip

I was wondering about what utility fits best ZIP extraction: gunzip? unzip? bsdtar? 7z?

P. S.: I'd like to take advantage of GNU parallel for speeding up the whole operation (I'm using SATA SSD devices).

Answer 1

Removing file extension when processing files:

parallel 'mkdir {.} && cd {.} && unzip ../{}' ::: *.zip
