Umask question
Hello All,

I was doing some work with umask and want to make sure I'm right.
I want newly created files to be executable for the group and the world, writable for the user only, and readable by the user, group, and world.

I came up with : umask 122 by assigning:
a 6 to user a 5 to group and 5 to world then subtracting 655 from 777 and getting 122?

Am i on the right track?
Thanks for looking.

Bob

cgcreate

CGCREATE(1)							 libcgroup Manual						       CGCREATE(1)

NAME

       cgcreate - create new cgroup(s)

SYNOPSIS

       cgcreate [-h] [-s] [-t <tuid>:<tgid>] [-a <agid>:<auid>] [-f mode] [-d mode] -g <controllers>:<path> [-g ...]

DESCRIPTION

       The command creates new cgroup(s) defined by the options -g.

       -a <agid>:<auid>
	      defines  the  name of the user and the group which own 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 permissions of a control groups directory.  The permissions needs to be specified as octal numbers e.g.	-d 775.

       -f, --fperm=mode
	      sets the permissions of the control groups parameters.  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).

       -g <controllers>:<path>
	      defines control groups to be added.  controllers is a list of controllers and path is the relative path to  control  groups  in  the
	      given controllers list. This option can be specified multiple times.

       -h, --help
	      display this help and exit

       -s, --tperm=mode
	      sets  the  permissions  of  the control group tasks file.  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).

       -t <tuid>:<tgid>
	      defines  the  name of the user and the group, which owns tasks file of the defined control group. I.e. this user and members of this
	      group have write access to the file.  The default value is the same as has the parent cgroup.
