I asked a different question for which the answer is appropriate here.
The sysutils package contains, among other things, two programs, fromdos
and todos. Fromdos removes ^M from files and todos inserts ^M before each
line feed, effectively converting a UNIX test file into a DOS text file.
fromdos will remove your carriage returns (^M).
