Question

I’m writing a bash script that needs to sudo multiple commands. I can do this:

( whoami ; whoami )

but I can’t do this:

sudo ( whoami ; whoami )

How do I solve this?

Answer 1

Run a shell inside sudo:
sudo bash -c 'whoami; whoami'

You can use any character except ' itself inside the single quotes. If you really want to have a single quote in that command, use '\'' (which technically is: end single-quote literal, literal ' character, start single-quoted literal; but effectively this is a way to inject a single quote in a single-quoted literal string).
