doas —
execute commands as another user
doas |
[-ns] [-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 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.
-n- Non interactive mode, fail if
doas would prompt
for password.
-s- 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:
- 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.
