DOAS(1) General Commands Manual DOAS(1)


doasexecute commands as another user


doas [-Lns] [-a style] [-C config] [-u user] command [args]


The doas utility executes the given command as another user. The command argument is mandatory unless -C, -L, or -s is specified.
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.
Clear any persisted authorizations from previous invocations, then immediately exit. No command is executed.
Non interactive mode, fail if doas would prompt for password.
Execute the shell from SHELL or /etc/passwd.
-u user
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:


su(1), doas.conf(5)


The doas command first appeared in OpenBSD 5.8.
