unix2dos - convert text file from ISO format to DOS format

unix2dos [-ascii] [-iso] [-7]

[-437 | -850 | -860 | -863 | -865] originalfile convertedfile

The unix2dos utility converts ISO standard characters to the corresponding characters in the DOS extended character set.

This command may be invoked from either DOS or SunOS. However, the filenames must conform to the conventions of the environment in which the command is invoked.

If the original file and the converted file are the same, unix2dos will rewrite the original file after converting it.

The following options are supported:


Adds carriage returns and converts end of file characters in SunOS format text files to conform to DOS requirements.


This is the default. Converts ISO standard characters to the corresponding character in the DOS extended character set.


Converts 8 bit SunOS characters to 7 bit DOS characters.

On non-i386 systems, unix2dos will attempt to obtain the keyboard type to determine which code page to use. Otherwise, the default is US. The user may override the code page with one of the following options:


Use US code page


Use multilingual code page


Use Portuguese code page


Use French Canadian code page


Use Danish code page

The following operands are required:


The original file in ISO format that is being converted to DOS format.


The new file in DOS format that has been converted from the original ISO file format.

File filename not found, or no read permission

The input file you specified does not exist, or you do not have read permission. Check with the SunOS command, ls -l (see ls(1)).

Bad output filename filename, or no write permission

The output file you specified is either invalid, or you do not have write permission for that file or the directory that contains it. Check also that the drive or diskette is not write-protected.

Error while writing to temporary file

An error occurred while converting your file, possibly because there is not enough space on the current drive. Check the amount of space on the current drive using the DIR command. Also be certain that the default diskette or drive is write-enabled (not write-protected). Notice that when this error occurs, the original file remains intact.

Translated tmpfile name = filename.
Could not rename tmpfile to filename.

The program could not perform the final step in converting your file. Your converted file is stored under the name indicated on the second line of this message.
