NAME

       getext - get VxFS extent attributes

SYNOPSIS

       file...

DESCRIPTION

       displays extent attribute information associated with a set of files.

   Options
       recognizes the following options:

	      Do not print the filenames for which extent attributes are displayed.

	      Specify the VxFS file system type.

	      Do not print output for files that do not have fixed extent sizes
			     or reservations.

	      Echo the completed command line, but do not execute the command.
			     The command line is generated by incorporating the user-specified options.  This option allows the user to verify the
			     command line.

   Operands
       recognizes the following operand:

	      file	     Name of file in a VxFS file system.

   Notes
       Only the and allocation flags (set through setext(1M) or the ioctl) are persistent attributes of the file and therefore visible via or  the
       ioctl.  is also visible, although it is cleared and the reservation is reduced on the final close of the file.

EXAMPLES

       The  following  example	shows a file with a block size of 1024 bytes, 36 blocks reserved, a fixed extent size of 3 blocks, and all extents
       aligned to 3 block boundaries:

       The file size cannot be extended once the current reservation is exhausted.  Reservations and fixed extent sizes are allocated in units	of
       the file system block size.
