mwrite(1)mwrite(1)NAMEmwrite - mtools utility to perform a low level write (copy) of a UNIX
file to DOS
SYNOPSISmwrite [-mntv] unixfile msdosfile
mwrite [-mntv] unixfile [unixfiles...] [msdosdirectory]
Preserves the file modification time. Specifies that a warning is not
issued when an existing file is specified as the target file. If this
option is not specified, the mwrite command verifies whether or not to
overwrite an existing file. Specifies a text file transfer. Line ter‐
minators are converted to the appropriate format. Specifies verbose
mode. Displays the new file name if the UNIX file name requires con‐
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 file name. If an invalid name is specified, the
mwrite command changes the name, then displays the new name if the -v
option is specified.
DOS subdirectory names that contain the '/' or '\' separator are sup‐
ported. If you use the '\' separator or wildcards, you must enclose
file names 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 file names are supported in the DOS world. The mwrite
command may have to change UNIX names to fit the DOS file name conven‐
tions. The following table shows some examples of file name conver‐
UNIX name DOS name Reason for the change
thisisatest THISISAT file name too long
file.stuff FILE.STU extension too long
prn.txt XRN.TXT PRN is a device name
.abc X.ABC null file name
hot+cold HOTXCOLD illegal character
The following exit values are returned: Success. Failure.
The following environment variables affect the execution of mwrite: If
set, this variable names the file that contains the name of the current
mtools working directory as established by the mcd command. If this
variable is not set, the file $HOME/.mcwd is used.
Contains the name of the current mtools working directory as estab‐
lished by the mcd command. If this file does not exist, the default
mtools working directory is A:\. Executable file
