How to unzip multiple zip files into a single directory structure (e.g. Google Drive folder export)
Solution 1:
Move the set of files you want to unzip to a dedicated directory, and then use unzip:
$ unzip '*.zip' -d combined
Archive: 1.zip
creating: combined/A/
creating: combined/A/inner_dir/
extracting: combined/A/inner_dir/file1.txt
Archive: 2.zip
extracting: combined/A/inner_dir/file2.txt
2 archives were successfully processed.
Check:
$ tree combined
combined
└── A
└── inner_dir
├── file1.txt
└── file2.txt
2 directories, 2 files
