Thanks!

I'd do 'umask 133' in front of the echo out of paranoia.

Out of curiosity, was the asterisk after '2>/dev/null' intentional? I had not seen that idiom before.

the asterisk is my oops, trying to format the comment in italics to differentiate my comment from the text provided by the author. sorry for the confusion

And I would do chattr +i disable-algif.conf
