Actually just realised what your problem is.

You wrote the file under Windows and transfered it to the ts7800.
The file will have DOS end of line termination which is the 2 character
sequence CR (ASCII 13) LF (ASCII 10). Linux (and unices in general)
expect lines to be terminated JUST with LF (ASCII 10).

You need to strip out the CR's. 

Try this on the ts7800

 $ tr -d '\015' < Helloworld.sh > Helloworld2.sh
 $ chmod 755 Helloworld2.sh
 $ ./Helloworld2.sh

The tr removes CR (in octal 13 is 015, "man tr" tells you about tr)

Try to write scripts on the Linux system itself.

cheers
Jim
