permissions
My /tmp is set with the following permissions (777) and a 't' at the end.

My umask is set to 022.

When I create a directory under /tmp (tmp/xx) it gets created as 755
as expected.

Yet when I create a file within that directory (/tmp/xx/yy) the permissions
are not 755 they are 644.

Can somebody please explain. Secondly, how do I force the permissions
on a file to inherit the parent directories permissions regardless of what
my umask is set too.



Code:
 
umask
022

ls -ld /tmp
drwxrwxrwt   9 root     root        1464 Nov 15 09:14 /tmp
 
 ls -ld /tmp/xx
drwxr-xr-x   2 oracle   dba          117 Nov 15 09:17 /tmp/xx
 
ls -lt /tmp/xx/yyy
-rw-r--r--   1 oracle   dba            0 Nov 15 09:17 /tmp/xx/yyy

cgconfigparser

CGCONFIGPARSER(8)						 libcgroup Manual						 CGCONFIGPARSER(8)

NAME

       cgconfigparser - setup control group file system

SYNOPSIS

       cgconfigparser [-h] [-l <filename>] [-L <directory>] [...]

OPTIONS

       -h, --help
	      Displays help.

       -l, --load=FILE
	      Parses  the  control  groups  configuration  file Sets up the control group file system defined by the configuration file and mounts
	      mount points defined by the configuration file.  The format of the file is described in cgconfig.conf. This option can be used  mul-
	      tiple times and can be mixed with -L option.

       -L, --load-directory=DIR
	      Finds  all  files in given directory and parses them in alphabetical order like they were specified by -l option. This option can be
	      used multiple times and can be mixed with -l option.

       -a <agid>:<auid>
	      defines the default owner of the rest of the defined control group's files. These users are allowed to set subsystem parameters  and
	      create subgroups.  The default value is the same as has the parent cgroup.

       -d, --dperm=mode
	      sets the default permissions of a control groups directory.  The permissions needs to be specified as octal numbers e.g.	-d 775.

       -f, --fperm=mode
	      sets  the default permissions of the control group files.  The permissions needs to be specified as octal numbers e.g.  -f 775.  The
	      value is not used as given because the current owner's permissions are used as an umask (so 777 will set group  and  others  permis-
	      sions to the owners permissions).

       -s, --tperm=mode
	      sets the default permissions of the control group tasks files.  The permissions needs to be specified as octal numbers e.g.  -f 775.
	      The value is not used as given because the current owner's permissions are used as an umask (so 777 will set group and  others  per-
	      missions to the owners permissions).

       -t <tuid>:<tgid>
	      defines  the default owner of tasks file of the defined control group. I.e. this user and members of this group have write access to
	      the file.

ENVIRONMENT VARIABLES

       CGROUP_LOGLEVEL
	      controls verbosity of the tool. Allowed values are DEBUG, INFO, WARNING or ERROR.
