I have a shell script working on SCO Unix 5.0.6. The problem is when I copy the script to another machine with SCO Unix 5.0.7 (and also other OS) then it is not running. It shows a syntax error.

Note that when I copy all instructions and paste them in command line then they work perfectly. However, as I said they are not working as one script file.

As example in the script I have:

case "${MODUS}" in

And I get the below error:

syntax error near unexpected token '$'in\r''

Base on the error it seems to me something is added at the end of each instruction.

In some cases when the error is at the end of the instruction I can fix the problem. I add a space and #(to consider the rest line as comment) at the end of each instruction. Then it works. However, the problem is that I cannot do that for all instructions. In some cases the error is in middle of the instruction and then (space#) not working.

Please let me know what is the reason for the error and how can I fix that.

Looks like your script has DOS line endings, the error even mentions it: in\r. You need to remove them.

How can I prevent this, when I copy the file?
Don't use Notepad to "copy" files? You didn't say how are you doing the copying.
No, I don't think you do.
You can strip trailing carriage returns with sed -i 's/\r$//' file
@glennjackman - are you sure that GNU sed notation works in SCO Unix's sed? I'm suspicious of the -i without a null OPTARG, as well as support for \r.
