The argument is a text string containing comma-separated keywords and values. These are passed to the modules that handle particular formats to control how those formats will behave. Each option has one of the following forms: key=value The key will be set to the specified value in every module that supports it. Modules that do not support this key will ignore it. Then below, after the last option, it says: ... zip:compression=type Use type as compression method. Supported values are store (uncompressed) and deflate (gzip algorithm). If a provided option is not supported by any module, that is a fatal error. The first states that it is ignored, the latter states that it is a fatal error. The meaning of "any module" is subtle, at least for my feeble brain ;-)It suggests that options are passed to all modules, and each module is free to ignore options it does not understand. But at least one module must understand the option, or a fatal error is reported.
Yes, I got that, but it is confusing when you are intentionally passing to only one module, as in the original post, "xz:9", and considering that the "fatal error" and "ignore it" parts are listed in separate sections. Regardless, tar(1) has many options, so a little confusion is not unsurprising :-) -- DE _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[email protected]"
