NAME

7

SYNOPSIS

9       pam_umask.so [debug] [silent] [usergroups] [umask=mask]
10

DESCRIPTION

12       pam_umask is a PAM module to set the file mode creation mask of the
13       current environment. The umask affects the default permissions assigned
14       to newly created files.
15
16       The PAM module tries to get the umask value from the following places
17       in the following order:
18
19       ·   umask= argument
20
21       ·   umask= entry of the users GECOS field
22
23       ·   pri= entry of the users GECOS field
24
25       ·   ulimit= entry of the users GECOS field
26
27       ·   UMASK= entry from /etc/default/login
28
29       ·   UMASK entry from /etc/login.defs

40           If the user is not root, and the user ID is equal to the group ID,
41           and the username is the same as primary group name, the umask group
42           bits are set to be the same as owner bits (examples: 022 -> 002,
43           077 -> 007).
44
45       umask=mask
46           Sets the calling process´s file mode creation mask (umask) to mask
