Hidden - Visible to project administrators in configuration mode. This applies to sub-pages as well. Visibility: This page cannot be hidden Freeform - Page link hidden in the left navigation. Object IDs begin with an object prefix and end with a number.
For example, if you enter. Some valid object prefixes are:. Execute permission means that you're able to access the object to inject events to it. You can set this property as:. Valid permissions that can be used and combined are are defined by Screen permission masks.
If you want to grant access to an outside process, the only way to do so is to set the permissions for Others. However, by granting the Others permission, it includes all others. So, there's really no way to grant access to a particular outside process without giving access to everyone else. Unlike the integer permissions, the string permissions allow you to specify a specific context, process, process group, group, or user that's not the same as the owner of the object.
When using permissions as a string, the permissions masks integer are set, but only the bits that have an integer association with the string form. The following table shows permissions strings and their corresponding permissions masks:.
The id for specified contexts is the identifier of the context object. The ID of the context is returned. This string is used to set the permissions. The permissions string is a combination of r read , w write , x execute , and - no permission.
The permissions must be specified in this order. Here are some examples presuming a default set of permissions mask that includes owner privileges :. In this example, the permissions set in string form don't have corresponding permissions masks.
Despite not being accounted for in the integer value, the permissions that were set in string form are still applied. Despite not being accounted for in the integer value, the permissions that are set in string form are still applied.
Unlike setting permissions as an integer, setting permissions as a string is additive. Subsequent settings of permissions won't undo previous settings.
Therefore, users and both result in having rw- permissions. To remove permissions from user , you can call set again with the string permissions as: user Privileges Privileges are permissions that are controlled by roles.
Role Description Owner An owner is defined as whoever creates the object. The owner, by default, has privileges to get and set certain properties, to perform certain functions, and to grant user permissions.
User A user has privileges based on user permissions. These user permissions are granted by the owner of the object. By default, an owner has owner and user privileges. Manager A manager, by default, has privileges to get and set certain properties, and to perform certain functions. Consumer A consumer, by default, has privileges to get and set certain properties, and to perform certain functions.
You also need to use the uid and gid attributes to set the ownership correctly. To determine whether or not a utility needs to have the setuid or setgid permission set, see its entry in the Utilities Reference.
If you want to set permission fields for multiple files, you can specify the attributes on a single line, followed by the list of files. Note: Windows neither provides a umask nor properly reflects the file ownership and permissions. Some items brought into the image don't acquire ownership and permissions in the same way as files, directories, and symbolic links, however: Inline files Unless otherwise specified, the default user ID and group ID are those of the user running mkifs or 0 on Windows , and the default permissions are or on Windows.
Changing user ID, group ID, and permissions To change the user ID, group ID, and permissions for files when they are included in the image, prefix the item name with the appropriate attributes in the buildfile. Note: On a Windows host, mkifs can't get any file attribute except for the write w bit, which is based on Windows' read-only file attribute. You need to use the dperms attribute to specify these permissions explicitly and use the uid and gid attributes to set the ownership correctly.
For more information, see the mkifs uid , gid , and dperms attributes. Parent topic : OS Image Buildfiles.
