mwrite
mwrite(1) General Commands Manual mwrite(1) 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] OPTIONS
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 terminators are converted to the appropriate format. Specifies verbose mode. Displays the new file name 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 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 supported. 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 conversions: ----------------------------------------------- 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 ----------------------------------------------- EXIT STATUS
The following exit values are returned: Success. Failure. ENVIRONMENT VARIABLES
The following environment variables affect the execution of mwrite: If set, this variable names the file that contains the name of the cur- rent mtools working directory as established by the mcd command. If this variable is not set, the file $HOME/.mcwd is used. FILES
Contains the name of the current mtools working directory as established by the mcd command. If this file does not exist, the default mtools working directory is A:. Executable file SEE ALSO
