umask=maskDESCRIPTION
pam_umask is a PAM module to set the file mode creation mask
of the current environment. The umask affects the default
permissions assigned to newly created files.
The PAM module tries to get the umask value from the
following places in the following order:
umask= argument
umask= entry of the users GECOS field
pri= entry of the users GECOS field
ulimit= entry of the users GECOS field
UMASK= entry from /etc/default/login
UMASK entry from /etc/login.defs
OPTIONS
Print debug information.
If the user is not root, and the user ID is equal to the
group ID, and the username is the same as primary group name,
the umask group bits are set to be the same as
owner bits (examples: 022 -> 002, 077 -> 007).
Sets the calling process's file mode creation mask (umask)
to & 0777. The value is interpreted
as Octal.
