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  ASCII and Unicode UTF-8 text files from the DOS format to the Unix format, while
       todos converts them 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     This option is deprecated. Do not use it unless you  know  what  you're  doing.  By
              default,  Tofrodos does the expected thing for text files. That is, when converting
              from DOS to Unix, it will remove carriage returns only if they are followed by line
              feeds.   When converting from Unix to DOS, it will add carriage returns only if the
              linefeeds are not already preceeded by carriage returns. When Tofrodos is run on  a
              normal  text  file  that  has  already been converted, the resulting file should be
              identical to the original. However, if you use this option, the program will always
              remove  carriage returns in the DOS to Unix mode and always add carriage returns in
              the Unix to DOS mode even if it is not appropriate.

       -b     Make a backup of original file. The original file with a .bak extension appended to
              the  original  filename,  silently  replacing  any existing file of that name.  For
              example, a file called  "filename.ext"  becomes  "filename.ext.bak"  replacing  any
              existing  file  having the name "filename.ext.bak".  Important: the program behaves
              differently if it is compiled for DOS (as compared to being compiled  for  Windows,
              Linux,  Mac OS X or other systems). In view of the filename restrictions present on
              DOS, the DOS executable will strip the original file extension, if  any,  from  the
              file  before  appending  the  .bak  extension.  For example, "filename.ext" becomes
              "filename.bak".

       -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 the
              program 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.

       -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 Unix-type systems (like Linux). On Windows and
              MSDOS, it only preserves the file  time.  Note  that  on  many  Unix-type  systems,
              including Linux, the file ownership will only be preserved if the program is run as
              root, otherwise it will just set the file time and silently fail the change of file
              ownership.  On  such systems, if you want a warning message when the file ownership
              cannot be changed, use -v (the verbose flag) as well.

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

       -v     Verbose.

       -V     Show version message and quit.

EXIT CODE

       Tofrodos terminates with an exit code of 0 on success and 1 on error.

       If the program is invoked with multiple files on the command line, the  default  behaviour
       is  to skip to the next file in the list if an error is encountered with any file. In such
       a case, the exit code returned will the status of  the  last  file  processed  (ie,  0  on
       success,  1 on failure). If this is not desirable, use the -e option, which will force the
       program to abort immediately with the appropriate exit code on encountering any error.
