DOAS(1) - General Commands Manual
NAME #
doas - execute commands as another user
SYNOPSIS #
doas [-Lns] [-a style] [-C config] [-u user] command [arg …]
DESCRIPTION #
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:
-a style
Use the specified authentication style when validating the user, as allowed by /etc/login.conf. A list of doas-specific authentication methods may be configured by adding an ‘auth-doas’ entry in login.conf(5).
-C config
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.
-u user
Execute the command as user. The default is root.
EXIT STATUS #
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.
