bash script under cygwin fails to recognize simple commands

[Bob Brusa]

Hi,
it seems I miss something. The primitive script t1.sh

#!/bin/bash
echo "script running"
ls -l
echo "script terminating"
exit 0

produces a rather unexpected result when running it from cygwin terminal:

rwb@w500 ~
$ ./t1.sh
script running
ls: unknown option --
„ls --help“ gibt weitere Informationen.
script terminating
: Ein numerischer Parameter ist erforderlich.

rwb@w500 ~

Why is this? Thanks for advice - Bob
