10.6 Console Commands
To start using a console password, type passwd -s and press Return. The
system displays a prompt (
pwd:
) asking you to type the password that you
want to use. Type a word with at least six characters. You can use letters
and numbers; the system recognizes the difference between uppercase and
lowercase letters.
The system displays the
pwd
: prompt twice. Type the same password each
time. For security reasons, the screen does not display what you type, so
choose a password that is easy to remember.
Once you choose a password, the system displays the restricted console prompt
when you first start your workstation:
R>
At this prompt, you can only boot your worksystem software or enter your
console password.
• Boot your worksystem software. Type
boot and press Return. This is
the only boot command that you can use. It has no options or arguments.
It uses the values that you set in the boot environmental variable (see
Section 10.7). If you have not set the variable, the command does not work.
• Enter your console password. Type passwd and press Return. Then type
your console password at the
pwd:
prompt. The screen does not display
what you type.
After you enter your console password, the prompt changes to the standard
console prompt (
>>
). You can now use all the console commands that are
described in this chapter.
To stop using your console password, type
passwd -c
at the standard console
prompt and press Return. You will then have unrestricted access to the console
commands.
10.6.12 printenv
>>printenv [env]
The printenv command displays the values of environmental variables. If you
specify the name of an environmental variable, the command displays the
value of only that variable. See Section 10.7.
