The problem is hat I passed the filename with the trailing dot to a Windows-Program which produced errors and corrupted the file without trailing dot.
Any idea how to fix it?

I'm afraid this is a case of WDDTT. You simply can't. Windoze is utterly
incapable of distinguishing between a filename that ends in a dot and the
same name without a dot at the end: it regards them as exactly the same
name. This is a leftover from the days of dos 8.3 names; a file called
"file" has no extension, and so for old style short dos names to work, it
has to be possible to refer to it as "file." - that is to say, it has a null
extension, and so the dot is optional.
Example:
-------->snip!<--------
C:\artimi.src\davek\dot>echo Hello world >file.test
C:\artimi.src\davek\dot>type file.test
Hello world
C:\artimi.src\davek\dot>type file.test.
Hello world
C:\artimi.src\davek\dot>dir
Volume in drive C has no label.
Volume Serial Number is 942E-907E

21/04/2004 14:21 <DIR> ..

The *only* solution is to rework your program so it doesn't rely on having
identically-named files that differ only in a trailing dot. Why not use a
trailing ~ insted? That's a fairly *nix way of doing things.

A man walks into his Doctor's office. "Doctor, whenever I do this it
hurts", he says, twisting his arm into an uncomfortable contorted position
behind his back.
"Well, Don't Do That Then", the doctor says. "Next!"

Trailing dots are silently ignored by Windows.

Hi folk, I have ported a bash-script from UNIX to cygwin and have the Problem that test says that the file exist but there is no file with the given Name.
Here come some command to reproduce the problem.
Wed Apr 21 12:36:00 556 ls -al; if [ -e "load_evu.ctl." ] ;then echo "load_evu.ctl." exists;fi;
insgesamt 1
drwxr-xr-x+ 2 F.Braunb Domänen- 0 21. Apr 12:28 .
drwxr-xr--+ 12 F.Braunb ???????? 0 21. Apr 12:19 ..
-rw-r--r-- 1 F.Braunb Domänen- 285 21. Apr 12:35 load_evu.ctl
load_evu.ctl. exists
When I go on in the script and working with a file which does not exist I run in trouble.
Any idea how to fix it that test says the file exists?
Regards
Franz
