I have a script, ~/scripts/backup, owned by root, that mounts an
external UPS drive, creates a directory based on date, and backs up my
hard disk with the exception of a few directories.
I created a symlink to /etc/cron.weekly to automate the job, but
because the script is located in user's directory, it runs with user's
permission, and much of the backup has "permission denied".
So I tried to start the script with this snippet:
pw=<password>
sudo
echo $pw
which does not work. I have several questions:
a) Why does a script owned by root and run by root lack root's
permission just because it is in user's directory?
b) Why does the script snippet above not work?
c) How can I do what this script snippet intends without exposing my
plain text password?
