Subject: [PATCH] Cygwin: utils: chattr: Improve option parsing.
Interpret '-h' as '--help' only if last argument.
Who was the idiot using -h for help *and* the hidden flag? *blush*
I'd vote for --help to be changed to -H for the single character
option. The help output is very unlikely to be used in scripts,
so that shouldn't be a backward compat problem.
New patch attached.
Note that there is now the possibly unexpected (& hidden) behavior that
'chattr -h' without file argument clears the hidden attribute of cwd.
Uhm... why?
Because chattr uses '.' as default if no FILE argument is specified. The
same applies to all other '+-=MODE' arguments. The patch does not change
this behavior but of course enables it for '-h'.
Isn't that easily avoidable?
Yes: make FILE argument mandatory - but this would break backward
compatibility.
Another behavior (possibly inherited from lsattr) is also not very useful:
'chattr +-=MODE DIRECTORY' also changes the attributes of all elements
in the directory (not recursively). It is not possible to solely change
the attributes of a directory except if it is the current directory and
no FILE argument is passed. Fixing this would again break backward
compatibility.
Regards,
Christian
