Nope. This last one is equivalent to: tr '\012' '\015'

$ echo -en "test\nblah\n" >unix.txt
$ hexdump -c unix.txt
0000000 t e s t \n b l a h \n
000000a
$ tr '\012' '\015\012' <unix.txt >dos.txt.txt
$ hexdump -c dos.txt.txt
0000000 t e s t \r b l a h \r
000000a

Nope :) See the unix->dos comment.

You can use perl for this, though:

$ perl -pe 's/\n/\r\n/' <unix.txt | hexdump -c
0000000 t e s t \r \n b l a h \r \n
000000c
