Re: 2 files, same name, same dir

I can probably blame it on the Joe editor, which leaves trailing
spaces on lines in files too.  I wrote a program once to strip them
off, probably doesn't bother anybody else.  When you save a file it
prompts with a (previous) filename with the cursor at the end, bumping
the spacebar then would do it, I've hit other characters by accident
and had those end up in filenames.  I've been using Joe for ~20 years.

But a trailing space on a filename, after the extension, is pointless
to keep.  Probably featureitis to build in looking for them though.

um. Unix.

File names can have almost any character, and they are all equally valid
in all places in the file name.  This ain't CP/M or its derivatives
(like Windows).

(and it wouldn't surprise me if Linux "saves" you from this error, and
it would just make me hate it all the more)

Bingo, a trailing space.  I would have thought that would get trimmed
off somehow.  I don't normally put spaces in filenames, I must have
fat-fingered something.  But I see no reason to keep trailing spaces.

-rw-r--r--  1 alan  wheel25549 Oct 22 10:55 pi.c\$
-rw-r--r--  1 root  wheel25152 Oct 22 00:07 pi.c \$

Likely one of them has  space or so in it's name. Use  

$ ls -l | vis -l

or some variation.

Are you sure that the names are exactly the same?  env LC_ALL=C ls,
hexdump, etc
