Note the added -ba to get rid of CPU stats etc, and >> to chain with Mystic's addition of /dev/null etc. Otherwise 7z will interpret /dev/null as an additional filename.
All this makes me wonder if the other archivers would need the same thing (>>)? Or if perhaps this should have been added by Mystic instead?
I found the following in whatsnew.txt:
+ When executing archives, MUTIL in Unix will now automatically append
" /dev/null 2>&1" to the end of each archive execution command in order
to hide standard output and error messages. It was already adding "2>nul"
in Windows.
Perhaps this should have been ">> /dev/null 2>&1" instead?
Best regards
