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 format 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 arguments. 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 preceded 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 particu-
lar 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 for-
mat 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 from-
dos or todos finds that the file does not have write permission, it will not pro-
cess 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.
-l<logfile>
Log error messages to <logfile>. Note that if your command line has an error, such
as when you specify an unknown option, the error message for the command line
option error will be issued to stderr instead and not logged.
-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, otherwise 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 Unix to DOS. See the -d option above for more information.
-v Verbose.
-V Show version message and quit.
