 Which command, included by default with OpenBSD 6.3, allows you to execute a command as another user?

• doas
• sudo
• runas
• suid               

EXPLANATION

The doas(1) utility first appeared in OpenBSD 5.8, intended as a lightweight drop-in replacement for sudo(1), which stopped being included in the base system since OpenBSD 5.7. The sudo utility had a large codebase, with lots of customizable bells and whistles. Most users would never use the advanced features of sudo, so in an attempt to minimise the attack surface and make a simpler tool, Ted Unangst wrote doas.

Despite being smaller and with fewer options, it still aimed to retain the fine-grained control that people had come to expect of utilities such as sudo, as Ted Unangst describes in his blog post: https://https.www.google.com.tedunangst.com/flak/post/doas
