doas — execute commands as another user

Debian                                          January 16, 2021                                         DOAS(1)

       The  doas  utility  executes the given command as another user.  The command argument is mandatory unless
       -C, -L, or -s is specified.

       The user will be required to authenticate by entering their password, unless configured otherwise.

       By default, a new environment is created.  The variables HOME, LOGNAME, PATH, SHELL,  and  USER  and  the
       umask(2)  are  set  to  values appropriate for the target user.  DOAS_USER is set to the name of the user
       executing doas.  The variables DISPLAY and  TERM  are  inherited  from  the  current  environment.   This
       behavior may be modified by the config file.  The working directory is not changed.

       The options are as follows:

       -Cconfig   Parse  and check the configuration file config, then exit.  If command is supplied, doas will
                   also perform command matching.  In the latter case either ‘permit’, ‘permit nopass’ or ‘deny’
                   will be printed on standard output, depending on command matching  results.   No  command  is
                   executed.

       -L          Clear  any  persisted  authentications  from previous invocations, then immediately exit.  No
                   command is executed.

       -n          Non interactive mode, fail if the matching rule doesn't have the nopass option.

       -s          Execute the shell from SHELL or /etc/passwd.

       -uuser     Execute the command as user.  The default is root.

       The doas utility exits 0 on success, and >0 if an error occurs.  It may fail for  one  of  the  following
       reasons:

       •   The config file /etc/doas.conf could not be parsed.
       •   The user attempted to run a command which is not permitted.
       •   The password was incorrect.
       •   The specified command was not found or is not executable.

       The doas command first appeared in OpenBSD 5.8.
