To send ID and Password for each command using expect feature in bash script
Dear Tech Guys,

I am trying to send some commands on the local server and it always asks for user name and password after each command. To serve the purpose I am using expect function as follows:

Code:
#!/usr/bin/expect

set timeout 20



spawn "./data1.sh"

expect "Please Enter UserName: " { send "admin\r" }
expect "*Password: " { send "admin123\r" }

interact

where data1.sh have the say:

Code:
#!/bin/bash
command1
command2
command3

Now the problem is that, my expect script provides username and password for only command1 but not providing username and password for command2 onwards and stops at the username prompt. Please help me out to troubleshoot this issue.

viewsu

VIEW-OS(1)						      General Commands Manual							VIEW-OS(1)

NAME

       viewsu - change (virtual) user ID or become (virtual) superuser

SYNOPSIS

       viewsu [options] [username]

DESCRIPTION

       The viewsu command is used to become another user during a login session. Invoked without a username, viewsu defaults to becoming the supe-
       ruser. The optional argument - may be used to provide an environment similar to what the user would expect had the user logged in directly.
       This  command  is  the  View-OS	counterpart  of  the  su(1)  command.	The  value of $PATH is reset to /bin:/usr/bin for normal users, or
       /sbin:/bin:/usr/sbin:/usr/bin for the superuser. This may be changed with the ENV_PATH and ENV_SUPATH definitions in /etc/login.defs.

OPTIONS

       The options which apply to the viewsu command are:

       -c, --command COMMAND
	   Specify a command that will be invoked by the shell using its -c.

       -, -l, --login
	   Provide an environment similar to what the user would expect had the user logged in directly.

	   When - is used, it must be specified as the last viewsu option. The other forms (-l and --login) do not have this restriction.

       -s, --shell SHELL
	   The shell that will be invoked.

	   The invoked shell is chosen from (highest priority first):

	   o   The shell specified with --shell.

	   o   The shell indicated in the /etc/passwd entry for the target user.

	   o	/bin/sh if a shell could not be found by any above method.
