Manage the read/write/execute permissions that are masked out (i.e. restricted) for newly created files by the user. More information: <https://manned.org/umask>.

  • 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
