Cygwin allows you to use either CR/LF or LF line endings - it's a registry key setting, IIRC.

Try running dos2unix on your shell script to change CR/LF to LF.

I completely missed page 2 of this thread when I wrote the following Smilie

This example will insert 'file.txt' between line 1 and 2 of source.txt.
Code:
sed '0r file.txt' <source.txt >desti.txt

gives an error message.

Does anyone know how 'sed' can insert 'file.txt' before the first line of source.txt?

I like ctsgnb's cat suggestion. However, if your life depends on using sed, you could swap the order of files:
Code:
sed '$r source.txt' < file.txt > desti.txt

If this is part of a larger sed task and swapping the order is not palatable, and if you are certain that there's more than one line in source.txt, you could use the following in a sed script:
Code:
1 {
    r file.txt
    h
    d
}

2 {
    H
    g
}

What is the 'H' command doing? Why is it required?

H appen newline + patternspace into the hold space
h would replace instead of appen
