CVS: does it have eol-style props

[KM]

can you or do you have to set the end of line characters or anything in CVS 
files?  We have a weird error. file is a shell script ...everything looks 
normal in vi w/ set list etc.   if we run unix2dos file seems to work.
 
when we put it back into cvs doesn't seem to work after we check it out.  
 
it says 
+ $'\r'
: command not foundheduledjobs.sh: line 4:

hidden character seems to be at end of line.
 
weird... thx
