|
- Display the current mask in octal notation:
|
|
|
|
|
|
|
|
|
|
`umask`
|
|
|
|
|
|
|
|
|
|
- Display the current mask in symbolic (human-readable) mode:
|
|
|
|
|
|
|
|
|
|
`umask -S`
|
|
|
|
|
|
|
|
|
|
- Change the mask symbolically to allow read permission for all users (the rest of the mask bits are unchanged):
|
|
|
|
|
|
|
|
|
|
`umask {{a+r}}`
|
|
|
|
|
|
|
|
|
|
- Set the mask (using octal) to restrict no permissions for the file's owner, and restrict all permissions for everyone else:
|
|
|
|
|
|
|
|
|
|
`umask {{077}}`
|
