“You should only use su if there is no other option”

What? Really, blanket sudo is worse than su.

What is wrong with:

su -c '> /var/log/uptime.log'

(Hint: nothing)

Regarding the solution in.the article that uses:

$ su 
$ sudo ...

What is the purposeof the ‘sudo’? Again: nothing.

Regarding killing processes using pidof and then kill, it can be more effecrive to use pkill (if you are unfamiliar with pkill, you van use prgrep to see which processes pkill would kill, they take mostly the same optioms).
