chmod 666 ///

[Bruce Hyatt]

This is stretching my knowledge of bash. The main point about
which I'm not sure is the brackets([]).

I'm accustomed to these being used for optional parts of a
command but the apostrophe before and after the brackets makes
me wonder. Plus the fact that brackets are used for "filename
metacharacters" which it appears could be the case here.

Should I enter the brackets as part of the command?

Also, I have version 4.3.1 of rpmpopt. There's a command there
(alias --setperms) that's identical but diverges somewhat after
"\(none\)". Does that matter?

Thanks again,
Bruce
