I recently upgrading to Snow Leopard. I have noticed that some files written by MacPorts are installed with the wrong permission -- they are written with a umask of 0077. I think I have narrowed down the problem:
port command is invoked via sudo..bashrc file specifies a umask of 0077.Is there anyway to have sudo use the old behavior? Right now, it's kind of annoying because I have to use sudo to run simple commands like port installed, port outdated, etc.
(The problem is described in more detail in this MacPorts ticket.)
I discovered the umask option for sudo, and in /etc/sudoers I added the following line:
Defaults umask=0022
However, this did not function as desired, because the real umask used by sudo is the union of the user mask with this default mask. In order to override the behaviour of sudo's umask and use the default directly (i.e., not the union of the user and default sudo mask), one can add the following:
Defaults umask_override
I ended up adding the following to my .bashrc configuration script:
# Mimic old behavior of `sudo` on OS X Snow Leopard
sudo() {
old=$(umask)
umask 0022
command sudo "$@"
umask $old
}
