using umask with sudo causes error

kinkle · 04-10-2009, 04:33 PM

Code:

sudo -u someuser umask 003

outputs this error:

Quote:

sudo: umask: command not found

But if I do:

Code:

su someuser
password
umask 003

Then, everything works out.

Any ideas why sudo won't work with umask? (It works with other commands)

umask is not a command, but a built-in function of bash. When you run sudo it doesn't spawn a shell, just executes the command directly, so without bash there, umask doesn't exist. umask isn't persistent though, so if that did work it'd set it and then instantly wipe out the change.
