This is probably "MS-DOS" type text file. MS text file lines
all end in a CR-LF character pair whereas UNIX text file lines
have only a LF (line feed) and the end of each line.
All text editors on MS systems do that and if you do a binary transfer
of a file from MS to UNIX you will get all the extra ^M characters
showing up. most versions of ftp have an ASCII mode that will
do the conversion for you as you transfer the file back and forth
between MS and UNIX. I think SCP only does binary transfers.

You can easily use tr(1) to remove all the ^M characters from a
file. tr -r "\r" <badfile >goodfile
where badfile is the one with the ^M characters and goodfile is
the newly cleaned copy. The only anoying thing is having to
write to a second file and then get rid of the first or mv the
new one back to the old (as in: mv goodfile badfile after doing
