Hi Sunny,

There are special tools for converting files
from Unix to DOS and back again. They
are 'dos2ux' and 'ux2dos'

There is a man page detailing both commands.

Using these two utilities, there is no need
to try and edit them using vi.

Hi,

Without using vi, you can also do:

# cat dosfile | col -b > unixfile

OR:

# strings dosfile > unixfile

Hope this helps. Regards.

You files have this ^M at the end of each line because you are FTP'ing the file from Unix to Dos in Binary mode.
Switch to Ascii mode (type 'asc' at the ftp prompt) before sending text files, and you won't have this problem.

Hope this helps.
