There are at least three things involved: rm, the shell and the user. If
the shell would do some unexpected extensions, I might get unexpected
results: that's the reason why the file name is defined in the program
and not handed over on the commandline. Both the shell and rm are
probably fine and work as they are supposed to. The user may easily
overlook something. It wasn't something I could have tried out in
advance very well, and writing the program took only a few
minutes. Better save than sorry ...

You can't have tried very hard then: 'touch -- "-rf *"'.

See above.

Unfortunately that happened several years ago with some elses portable
drive - I only noticed the problem when moving the music collection from
ext3 to ext4 - the system kept coming up with "not found" messages when
attempting to move filenames which had ISOcharacter set accented
characters.

Fortunately I've managed to rename them using Picard and MusicBrainz -
there's far too many to do by hand.

This thread was created by someone else with a similar problem - so the
solution might be more use to them. I'm curious as to how it happened so
I can avoid it in the future though. Especially as I increasingly come
across people using the old non-UTF character sets for files.

What I should do is create some rules so that when I mount ntfs and fat
volumes in the future the problem is avoided... any suggestions'd be
appreciated.

You are (also) correct.
Turns out there's a number of ways to do that.

What does the "--" do??
Both:-
$ touch "-rf *"
and:-
$ touch -- "-rf *"
work - so "--" doesn't "appear" to do anything, yet it produces no
error. Strange - I'd expect an error at least.

POSIX standard is for -- to signify end of options, so anything beyond that
cannot be processed as a switch/option.

Thanks -- should prove very useful (much simpler safety than other
proposals). Also explains why it didn't throw an error.
I remember seeing it before (IRIX and AIX) but, um, don't think I'd ever
bothered to asking why :-(.

For this kind of weird issues, what it usually helps is mounting the

device manually (with "mount" command) and trying to write a file in

there, also, from command line. Hopefully the error you get can shed some

light on the problem.

the device is being mounted correctly so no error is reported, but I still can't create/write filenames with accented chars.

touch './-rf *'

The ./ prefix is the key to removing it afterwards, too.

Put here the output you get when you try to save a file with accented
characters on its filename, but do it from command line, do not use GUI
applications because sometimes, more than helping, quietly silence the
underlaying problem.

For instance:

sm01@stt008:~$ echo sample > áéíóú.txt
sm01@stt008:~$ file áéíóú.txt
áéíóú.txt: ASCII text
sm01@stt008:~$ cat áéíóú.txt
sample
