mwrite(1) — Commands
NAME
mwrite − mtools utility to perform a low level write (copy) of a UNIX file to DOS
SYNOPSIS
mwrite [-mntv] unixfile msdosfile
mwrite [-mntv] unixfile [unixfiles...] [msdosdirectory]
FLAGS
-mPreserves the file modification time.
-nSpecifies that a warning is not issued when an existing file is specified as the target file. If this flag is not specified, the mwrite command verifies whether or not to overwrite an existing file.
-tSpecifies a text file transfer. Line terminators are converted to the appropriate format.
-vSpecifies verbose mode. Displays the new filename if the UNIX file name requires conversion.
DESCRIPTION
The mwrite command copies the specified UNIX file to the named DOS file, or copies multiple UNIX files to the named DOS directory. The destination directory cannot be omitted. Reasonable care is taken to create a valid DOS filename. If an invalid name is specified, the mwrite command changes the name, then displays the new name if the -v flag is specified.
DOS subdirectory names that contain the ’/’ or ’\’ separator are supported. If you use the ’\’ separator or wildcards, you must enclose filenames in quotes to protect them from the shell.
The mcd command can be used to establish the device and the current working directory (relative to DOS), otherwise the default is A:\.
Not all UNIX filenames are supported in the DOS world. The mwrite command may have to change UNIX names to fit the DOS filename conventions. The following table shows some examples of filename conversions:
| UNIX name | DOS name | Reason for the change |
| _ | _ | _ |
| thisisatest | THISISAT | filename too long |
| file.stuff | FILE.STU | extension too long |
| prn.txt | XRN.TXT | PRN is a device name |
| .abc | X.ABC | null filename |
| hot+cold | HOTXCOLD | illegal character |
