NAME
tofrodos - Converts text files between DOS and Unix formats.

SYNOPSIS
fromdos [ options ] [file...]
todos [ options ] [file...]

DESCRIPTION
DOS text files traditionally have carriage return and line feed pairs
as their newline characters while Unix text files have the line feed as
their newline character. fromdos converts text files from the DOS for‐
mat to the Unix format, while todos converts text files from the Unix
format to the DOS format.

The programs accept multiple filenames and wildcards as their argu‐
ments. You may also use them in a pipe. If either program finds its
input redirected, it will process stdin and place the output on stdout.

OPTIONS
-a Always convert. If converting from DOS to Unix, this option will
cause the program to remove ALL carriage returns. The default is
to remove carriage returns only if they are followed by line
feeds. If converting from Unix to DOS, this option will cause
the program to convert ALL linefeeds to carriage return pairs.
The default is to convert linefeeds only if they are not already
preceeded by a carriage return.

-b Make a backup of original file. The original file is renamed
with the original filename and a .bak extension.

-d Convert from DOS to Unix. This forces the program to convert the
file in a particular direction. By default, if the program is
named fromdos or dos2unix, it will assume that the input file is
in a DOS format and convert it to a Unix format. If the program
is named todos or unix2dos, it will assume that the input file
is in a Unix format and convert it to a DOS format. Using the -d
option forces the program to convert from a DOS format to a Unix
format regardless of how the program is named. Likewise, using
the -u option forces the program to convert from a Unix format
to a DOS format regardless of the name of the program.

-e Abort processing on any error in any file. Normally, the program
will simply skip to process the next file on the command line
when it encounters any errors. This option causes it to abort on
errors.

-f Force: convert even if the file is not writeable (read-only). By
default, if fromdos or todos finds that the file does not have
write permission, it will not process that file. This option
forces the conversion even if the file is read-only.

-h Display a short help screen on the program usage and quit.

-o Overwrite the original file (no backup). This is the default.

-p Preserve file ownership and time. On systems like Linux, the
file ownership will only be preserved if the user is root, oth‐
erwise it will just set the file time and silently fail the
change of file ownership. If you want a warning message when the
file ownership cannot be changed, use -v.

-u Convert from DOS to Unix. See the -d option above for more
information.

-v Verbose.

-V Show version message and quit.

tu vois que l'option -n n'est pas dans le man.
Etudie-le et regarde quelle autre option utiliser.

Mmm, un tr fait tout aussi bien l'affaire...

cat format_dos | tr "\r" " " > format_unix

De toute façon, moi, j'ai mis ces deux fonctions dans mon .emacs, et du coup, j'ai juste à éditer le fichier en question et appeler ces fonctions ;-)
