Very Computer

Dear all,

    My computer have many AIX SP UNIX servers needed to install a software.
The installer of the program required to input a initial password. In order
to speed up the installation, I want to write a script to accomplish this
task. However, I found that I cannot input a password to the install program
inside the script.

i.e.

install << EOF
option1
option2
...
initial_password
optionn
EOF

The script always stop at the "initial_password line. Do any one have idea
how to input the password to program inside the script?
For a simple reproduction of the case, we may try this script

passwd << EOF
old_password
new_password
new_password
EOF

Thanks a lots!

The passwd program reads the password from /dev/tty, not standard input.
You'll need to write an Expect script to do what you want.

Yes, the expect package includes an expect script to do exactly that.
It might still be available in AIX package format from the Bull
archives, although I don't remember what the new name is; it used to
be www-frec.bull.com.

Or you could use the AIX Tools v1.5.1 Collection
(freeware.aix.tools.rte) from the Bull site :

http://freeware.bull.net/

It contains a short program called 'chpass' (in /usr/local/lib/tools)
which will set the password for you. Remember to run the command
'pwadm -f ADMCHG <user>' if you want the user to change the password
at next logon.
