Bash Scripts for Audio-Visual PreservationIt is easier to port a shell than a shell script.
Bash AVpres is a set of Bash scripts for audio-visual preservation, used on a daily base at our conservation and restoration lab, AV Preservation by reto.ch.

The scripts are released under a 3-Clause BSD License and provided “as is” without warranty or support of any kind. Bug reports are very welcome, as usual. Elements of the Set

However, we strongly advise to install the current Bash version 5.1 (released on 2020-12-07) also on computers running under macOS.
