Having a script executed for all users?

[Darragh]

Hello all,
I want to include the following two lines in a script that will execute
no matter who is logging on.

Echo 25 > /proc/speakup/apolo/jiffy_delta
Echo 10 > /proc/speakup/apolo/delay_time

I tried putting it into the /home/darragh/.bash_profile file but As far
as I can tell that file is executed after I log in and I don't have
write permission for the two files.

Thanks
