       chkstat [--set|-set] [--noheader] [[--examine file ]...]  [[--files filelist ]...]  [[--root directory ]...]  permission-file ...

DESCRIPTION

       The program /usr/bin/chkstat is a tool to check and set file permissions.

       Multiple  permissions  files can be given on the commandline.  If the permission files contain multiple entries for a single file, the last
       entry found will be used.

   General Options
       --set, -set
	      This option enables setting the file permissions, the default is to check and warn only.

       --noheader
	      Omit printing the output header lines.

       --examine file
	      Check permissions for this file and not all files listed in the permissions files.

       --files filelist
	      Check permissions for the files listed in filelist and not for all files listed in the permissions files.

       --root directory
	      Prefix the files given in the permissions files by this directory.

EXAMPLE

       The command

	      chkstat -set /etc/permissions

       will parse the file /etc/permissions and set the access mode and the user- and group memberships each file listed. The format for the input
       file is

       FILEPATH OWNER:GROUP MODE

       and wildcards are not supported for the filepath. Lines starting with '#' and empty lines are treated as comments.
