Any ideas? Maybe some bash scripting or some useful command-line utilities? I came across "pigz" (https://linux.die.net/man/1/pigz) today by accident...

I like unar, the “universal unarchiver”. It can list and extract zip, tar, 7z, rar -- essentially, all the common formats, in one utility.

Though I was slightly disappointed to learn recently that its handling of file timestamps left a little bit to be desired ...

Recently, I had a zip file (got generated on Windows) where unzip spit its dummy: error [XYZ.zip]: start of central directory not found; zipfile corrupt. However, using 7z instead solved that for me. And I just tested unar and it didn't complain either. Nice! I might use that from now on. :-) Since there hasn't been any other input regarding next week's meeting, I'll just propose to have a group session around bash programming and command-line utilities: https://www.meetup.com/WaikatoLinuxUsersGroup/events/266792035/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
