There are a few methods to see non printing characters in a file.
Try 
cat -v filename 

In vi, in command mode you can do:
: set list
and all the 'funny' characters will be displayed.
Do:
: set nolist 
to make the file appear normal.

Personally whenever I come across an MS-dos file on Unix, I first
check it in vi with the :set list command and then I do a vi command
like:

:%s/<CTRL>v<CTRL>M//g

This is a substitute command. 
The % sign means apply the command to the whole file
s means substitute.
/ is the delimiter
<CTRL>v means dont interpret the next keystroke
<CTRL>M is the 'funny' character you want to get rid of. In this case
it is control M, though you may find something else in your
particuliar file. g means do the command globally ie do it as many
times as necessary on each line.

Of course if it all goes wrong, you can type u in command mode and the
change will be undone :-)

Hope this helps.

John Kelly
