Read umask for a user

Question

Plenty of examples on how to set umask for a user... but how do you read (or uncover) the default umask for a given user (say the logged in user)

Answer 1

With the umask command...

dennis@lightning:~$ umask
0002

Answer 2

To make sure a command is called with a specific command, you could wrap it inside a script or a function that starts a subshell with the umask updated. You could put that function definition in your shell configuration file like .bashrc for bash or .zshrc for zsh.

Something like:

brew() (
  umask 002 &&
    command brew "$@"
)
