Re: A file is not always what you think it is.
That sounds suspicious. Hmmm. Are you sure that the permissions *and*
the ownership were set properly for *you* to execute it? After all, a
text file is just a text file. The only variation would be CR/LF line
endings. In fact, the .txt extension should be no barrier to running a
script, as long as the ``shebang'' (#!...) line at the beginning is
correct. The other thing... are you sure that the file was in your
path? It's common practice *not* to include the working directory in
the path of user Root, for instance.
I've never had trouble copying things via DOS diskettes, as long as the
concerns you are addressing are taken care of. I usually use mtools.
OTOH, if you mount a DOS filesystem (preferably as a VFAT filesystem),
some of the permissions and the ownership are determined on a
by-filesystem basis, via the mount command. (I don't recommend mounting
DOS floppies, because if you forget to unmount before removing, you've
got problems.)
