doas (“dedicated openbsd application subexecutor”)[3] is a program to execute commands as another user. The system administrator can configure it to give specified users privileges to execute specified commands. It is free and open-source under the ISC license[4] and available in Unix and Unix-like operating systems.

doas was developed by Ted Unangst[5] for OpenBSD as a simpler and safer sudo replacement.[6][7] Unangst himself had issues with the default sudo config, which was his motivation to develop doas.[3] doas was released with OpenBSD 5.8 in October 2015 replacing sudo.[1] However, OpenBSD still provides sudo as a package.[1]

Transcription

Configuration

Definition of privileges should be written in the configuration file, /etc/doas.conf.[8] The syntax used in the configuration file is inspired by the packet filter configuration file.[3]

Examples

Allow user1 to execute procmap as root without password:[citation needed] 

permit nopass user1 as root cmd /usr/sbin/procmap

Allow members of the wheel group to run any command as root: 

permit :wheel as root

Simpler version (only works if default user is root, which it is after install): 

permit :wheel

To allow members of wheel group to run any command (default as root) and remember that they entered the password: 

permit persist :wheel

Ports and availability

Jesse Smith’s[9] port of doas is packaged for DragonFlyBSD,[10] FreeBSD,[11] and NetBSD.[12] According to the author, it also works on illumos and macOS.[13] OpenDoas, a Linux port, is packaged for Debian, Alpine, Arch, CRUX, Fedora, Gentoo, GNU Guix, Hyperbola, Manjaro, Parabola, NixOS, Ubuntu, and Void Linux.[14] Starting with Alpine Linux v3.16 release, OpenDoas became the suggested replacement for sudo, which got its security maintenance time reduced within the distribution.[15]
