Yup.  You're not quoting the backslash to keep bash from interpreting
it. This command:

              sed -e s/\r//

will get rid of all 'r's.  This one:

              sed -e 's/\r//'

will get rid of carriage returns.

Actually, sed does:

$ od -c foo.txt
0000000   T   h   i   s       i   s       a       t   e   s   t   .  \r
0000020  \n
0000021
$ sed -e 's/\r//' foo.txt | od -c
0000000   T   h   i   s       i   s       a       t   e   s   t   .  \n
0000020
