Bash scripting mask password from ps
Hi All,
I have a script, which prompts me for my password input, then it passes that password onto an argument for another script which is then passed onto an expect script which automates my logins to a bunch of servers to execute my commands.
example.
script A - request for password, pass password variable to expect script command
expect command - ./expect $password ssh@server “command”
expect script - obtain password from $argv 0 and execute.
I've seen a few posts about this request and can't find anything that works. Is anyone able to guide me in the right direction? I have tried using file descriptor and no luck.
Also, no ssh keys is not an option and hard coding passwords in files.
Thanks

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

X(1X), xdm(1X), passwd(1)
