I gave a look at 7zr documentation: https://manpages.ubuntu.com/manpages/focal/en/man1/7zr.1.html and I noticed parameters like this one: -x[r[-|0]][m[-|2]][w[-]]{@listfile|!wildcard} : eXclude filenames now, is this syntax standard or 7zr specific? where can I learn how to interpret this? I googled for hours, yet I'm not able to figure this out
