I didn't say it's portable. I said, it's _more_ portable. Editing
/etc/passwd directly may even be unportable on the same distribution
with a different version.

Most programs don't handle them properly. Even some text editors (like
GNU nano) fail there. One reason is that functions like fgets() do
return the CR character as part of the line.

Same with delimiter characters. Where Unix uses ':', Windows uses ';',
and where Unix uses '/', Windows uses '\'. Even basic system functions
names are totally incompatible, like poll() on Unix
vs. MsgWaitForMultipleObjectsEx() on Windows. Microsoft has
sufficiently reached the goal of making Windows programs as unportable
as possible. Wouldn't it be bad, if Photoshop ran equally well on Unix?

Ten screenfuls of source code just to create an empty OpenGL- or
D3D-enabled window via DirectX under Windows. A few more pages of code,
to make it closable. And you couldn't remember all those COM+ calls
needed, without having a browser to MSDN open. You couldn't even
remember their argument list. Even if you do for a single function;
what kind of argument is it? LPARAM, or DOWRD? Or even WINDOWCLASSEX?
Or CREATESTRUCT? Oh, please don't forget, you have to use LPCTSTR
instead of char *.

And (writing this in an own paragraph because of identifier length)
please remember that the FrontEndUploadMemoryUtilizedPercent component
of the D3DDEVINFO_D3D9BANDWIDTHTIMINGS structure is of type FLOAT, not
float!

Same program in Unix via SDL uses just about thirty lines, and can be
done mostly with standard types. Poor Windows coders ...

Do your user names actually have the numbers int he names or are there just
9000 different names?

i=1000
for n in `cat nameoffile`
do
echo "$n:x:$i:1000::/home/$n:/bin/bash">>/etc/passwd
i=$(($i+1))
done

Finally someone with the reasonable answer. If he's working from a text
file with "^M" imbedded, he could A) vi the file and perform a global search
and replace, or B) pipe the output to sed using '/s[CTRL][v][CTRL][M]//g' to
remove the "^M" before using the useradd command.

That is exactly what /col/ was designed to do. Pipe the file
through /col/, using -x and perhaps -b options.
