chdosattr(1)                General Commands Manual               chdosattr(1)

NAME
       chdosattr - change DOS file attributes

SYNOPSIS
       chdosattr [ -RVH ] ATTR FILES...


DESCRIPTION
       chdosattr changes the following DOS attributes of files:

              r (READONLY)

              h (HIDDEN)

              s (SYSTEM)

              a (ARCHIVED)

       The format of ATTR is in two parts, in the format of [+-=][ahrs], where
       the first part is the operator spec the second part the DOS attributes.
       The operator + causes the specified DOS attributes to be added the
       existing DOS attribute set; - causes them to be removed; and = causes
       them to be added and causes unmentioned DOS attributes to be removed.
       If the operator part is omitted, = is assumed.


OPTIONS
       -R     Change files and directories recursively

       -V     Show version

       -H     Show help


EXIT STATUS
       0      on success

       1      when no file could modified

       2      on usage error

       3      when an error occurred but at least one file has been
              successfully modified


BUGS AND LIMITATIONS
       The modification of the DOS attribute s(SYSTEM) requires
       CAP_LINUX_IMMUTABLE(see capabilities(7)).


       For obvious reasons, the DOS attributes s(DIRECTORY) and v(VOLUME)
       cannot be altered.


NOTE
       In vFAT, exFAT and NTFS, only the READONLY attribute is controlled
       through owner write permission bit. Linux kernel always sets ARCHIVE on
       files it creates and modifies. HIDDEN and SYSTEM can only be controlled
       through  ioctl_fat(2).  lsdosattr(1) and chdosattr(1) are the wrappers
       for the ioctl.

       command in Microsoft Windows and various DOS.
