passwd Command
Use the passwd command to enter, set, or clear a password.
The passwd command format is
passwd
[
-c
] [
-s
]
If the console prompt is
R>
, you can use only the boot and
passwd commands until you enter the correct password.
To enter an existing password, type the passwd command
without any additional parameters. At the
pwd:
prompt, enter
the password. Then press Return.
After you enter the correct password, or if the system does not
require a password, the system displays the console prompt
>>
.
You can use all console commands whenever the console prompt
is
>>
.
To clear an existing password, include the -c parameter
when you type the passwd command. First use the passwd
command to enter the existing password. After the console
prompt
>>
appears, type passwd -c and press Return. The
system then removes the password requirement.
To set a new password, include the -s parameter. Enter the
new password at the
pwd:
prompt. When the
pwd:
prompt
appears a second time, type the password again. If the two
password entries match, the system sets the new value as
the password.
The password must have at least 6 and no more than
32 characters. The system is case sensitive and treats
uppercase and lowercase letters as different characters.
printenv Command
Use the printenv command to display the list of environment
variables.
The printenv command format is
printenv [ variable ].
To display the entire environment variable table, omit the
optional variable parameter.
