Doas
doas (“dedicated openbsd application subexecutor”) 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 and available in Unix and Unix-like operating systems. doas was developed by Ted Unangst for OpenBSD as a simpler and safer sudo replacement. Unangst himself had issues with the default "sudo" config, which was his motivation to develop doas. doas was originally developed by Ted Unangst and was released with OpenBSD 5.8 in October 2015 replacing sudo. However, OpenBSD  still provides sudo as a package. Configuration. Definition of privileges should be written in the configuration file, /etc/doas.conf. The syntax used in the configuration file is inspired by the packet filter configuration file. Examples. Allow user1 to execute procmap as root without password: Allow members of the wheel group to run any command as root: Simpler version (only works if default user is root (after install it is)): To allow members of wheel group to run any command (default as root) AND remember that they entered the password: Ports and availability. Jesse Smith’s port of doas is packaged  for DragonFlyBSD, FreeBSD, and NetBSD. According to the author, it also works on illumos and macOS. OpenDoas, a Linux port, is packaged for Debian, Alpine, Arch, CRUX, Fedora, Gentoo, GNU Guix, Hyperbola, Manjaro, Parabola, NixOS, Ubuntu, and Void Linux.
