File descriptors -- cygwyn bash (windows)

Cygwin bash script was invoked in bash shell as follows:
Code:
/cygdrive/c/cygwin/bin/bash  test.sh

This is content of my script
Code:
 #!/bin/bash
 #
 exec 3</cygdrive/c/cygwin/home/work/part1.txt
 read -u 3 x
 echo $x
 exec 3<&-

Commands work correctly when issued one at a time within bash shell.
But when I attempt to run the shell script I get error messages like this:
Code:
: No such file or directoryc/cygwin/home/work/part1.txt
  test.sh: line 4: read: 3: invalid file descriptor: Bad file  descriptor
: not foundne 6: exec:

Any ideas on why the script fails?

Are you editing your scripts in Microsoft Notepad? It sounds like they may be full of carriage returns. tr -d '\r' < wingarbage > unixtext

thanks

I suspected it might be unprintable characters of some kind.
I'll check into it.
Thanks very much.
