  But, since it's what Patrick wants:

sed -b -e 's/\r$//g' < infile > outfile

ought to do the trick:

/artimi/chips $ od -c foo
0000000   l  \r   i   n   e       1  \r  \n   l   i   n   e   s       2
0000020  \r  \r  \n   l   i   n   e   s       3  \r  \n
0000034
@_______. .
(       /"\
 ||--||(___)
 '"  '"'---'
/artimi/chips $ sed < foo -b -e 's/\r$//g' | od -c
0000000   l  \r   i   n   e       1  \n   l   i   n   e   s       2  \r
0000020  \n   l   i   n   e   s       3  \n
0000031
@_______. .
(       /"\

 '"  '"'---'
/artimi/chips $

    cheers,
