There's also the "unar" package that contains the "lsar" program;
it can list the contents of dozens of different types of archive
files and print the listing in JSON, making it very friendly for
computer consumption.

Tools are here:    http://unarchiver.c3.cx/commandline
Supported formats: http://unarchiver.c3.cx/formats

Also, these tools are packaged in Debian.
