Full Discussion: Supply Password Thru Script
Operating Systems AIX Supply Password Thru Script Post 302170886 by bakunin on Wednesday 27th of February 2008 02:53:19 AM

I think it is less a question of using a specific tool but a question of how the application handles its input.

If the application asks for the password and then expects <stdin> to provide it you might be able to use one of the following constructs:

Code:
app < $(print - "<password>")
print - "<password>" | app
app < /file/with/password
cat /file/with/password | app

But with ssh (for instance) this would fail. Secure Shell doesn't use the regular <stdin> due to security reasons and you will have to provide the password either by exchanging keys (to speak generally: by applications means) or by hand. If your application falls into the same category all the ways mentioned above will fail.

dxchpwd(1X)															       dxchpwd(1X)

NAME
dxchpwd - Create or change password program SYNOPSIS
dxchpwd dxchpwd -r | -l dxchpwd [-r | -l] -q dxchpwd [-r | -l] -u username OPTIONS
If dxchpwd is invoked without any options, it is assumed that the current user's password is to be changed. The following options are also accepted: Tells dxchpwd that the password change is to be done for a Local user. This can be combined with the -u and -q options. Tells dxchpwd that the password change is to be done for a NIS user. This can only be done from a NIS master and can be combined with the -u and -q options. Tells dxchpwd to query the user for the user name of the account whose password is to be changed. Tells dxchpwd to change this user's password. DESCRIPTION
The dxchpwd command lets you change your password. When you invoke the dxchpwd command, the program prompts you for the old password and then for the new password. Next, the program asks you for the new password again, to verify that you have typed it correctly. Note that the passwords are not displayed on the screen. Your new password must meet the length requirements specified by the authorization database for the user whose password is being changed. If your system is running with enhanced security, you may have to choose a password from a list of randomly generated passwords or you may be prohibited from changing your password until its minimum lifetime has expired, as specified in the authorization database. EXAMPLES
The following example requests that the password be changed for user smith: dxchpwd -u smith FILES
Password file Protected Password Database dxchpwd executable SEE ALSO
X(1X), xdm(1X), passwd(1) dxchpwd(1X)
