Re: How do I convert a DOS file to a UNIX file?

["Alan R. Becker" <beckera mail-now com>]

Hello Scott,
If the majority of the files you need to migrate will 
be edited with vi, you can use vi to accomplish the 
dos-to-unix translation (ot the reverse).  Just set 
the file format and save the file.  For example,

:set ff=unix [enter]   or
:set ff=dos [enter]

followed by a ZZ to write and exit, and you are all set.

Another thought:  if FTP is responsible for the original 
translation, you may be able to avoid this by specifying 
BIN mode for the transfers (just use the BIN command in 
ftp).  Copying to a server, or burning CDs should not 
tamper with the internal structure of files, so FTP 
is the most likely culprit.  you can find out by looking 
at the file length in each environment:  the DOS version 
will be longer (2 chars per newline instead of 1) than 
the matching unix version.
