NAME
  mattrib - mtools utility to change DOS file attribute flags

SYNOPSIS
  mattrib [-a|+a] [-h|+h] [-r|+r] [-s|+s] msdosfile [msdosfiles...]

  The mattrib command sets (+) or clears (-) the attribute flags of a DOS
  file.

FLAGS
  -a|+a
      Sets or resets the archive bit.  Some backup programs use this flag to
      indicate a new file.

  -h|+h
      Sets or resets the hidden-bit. This flag hides files from the DOS DIR
      command.	To view these files, use the mdir command.

  -r|+r
      Sets or resets the read-only bit.	 This flag is used to indicate a
      read-only file.  If this bit is set, a file cannot be removed using the
      DOS DEL command.	To remove the file, use the mdel command.

  -s|+s
      Sets or resets the system bit.  This flag is used by DOS to indicate an
      operating system file.

DESCRIPTION
  The mattrib command sets the attribute flags of a DOS file using the plus
  (+) operator, or clears attribute flags using the minus (-) operator.	 DOS
  pathnames 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:\.
