3. sudo to appuser1 account on remote server. copy script file from my user home to /usr/bin/ folder.

Code:

#!/bin/bash

REMOTE_IP='30.20.138.25'
SCP_PASSWORD="Rkfasfafsafas"
SCP_REMOTE="myuserid@$REMOTE_IP:/home/myhome"
SCP_FILE=somefile.py

expect -c "
   set timeout 1
   spawn scp $SCP_FILE $SCP_REMOTE
   expect yes/no { send yes\r ; exp_continue }
   expect *assword: { send $SCP_PASSWORD\r }
   expect 100%
   sleep 1

   send "/bin/chmod 766 $SCP_FILE\n"
   expect "$"

   send "/usr/bin/sudo bin/su appUser1"
   expect *assword: { send $SCP_PASSWORD\r }

   send "/usr/bin/cp /home/myhome/$SCP_FILE /usr/bin\r"
   sleep 1
   exit
"

above script is copying file to remote server. send commands are failing.
couldn't read file "766": no such file or directory

How can I get rest of the code after first sleep 1 working? Do I need to initiate another SSH connection? Can I use ssh connection opened for scp and perform other commands?

Note that in your script the 1st argument passed to expect is -c and I have marked the 2nd argument to expect in red. That makes the 3rd argument passed to expect be the string 766 (which appears to be interpreted as a filename by expect thereby producing the diagnostic message you quoted).

If you want to pass quoted strings to commands inside the 2nd argument to expect, you need to escape the inner quotes. Note also that some of the arguments passed to send are quoted and some are not. I would assume that they should be consistently quoted or unquoted; not a mix.

bb-services

BB-SERVICES(5)							File Formats Manual						    BB-SERVICES(5)

NAME

       bb-services - Configuration of TCP network services

SYNOPSIS

       $BBHOME/etc/bb-services

DESCRIPTION

       bb-services contains definitions of how bbtest-net(1) should test a TCP-based network service (i.e. all common network services except HTTP
       and DNS).  For each service, a simple dialogue can be defined to check that the service is functioning normally, and optional flags  deter-
       mine if the service has e.g. a banner or requires SSL- or telnet-style handshaking to be tested.

FILE FORMAT

       bb-services is a text file. A simple service definition for the SMTP service would be this:

	  [smtp]
	     send "mail
quit
"
	     expect "220"
	     options banner

       This  defines  a service called "smtp". When the connection is first established, bbtest-net will send the string "mail
quit
" to the
       service. It will then expect a response beginning with "220".  Any data returned by the service (a so-called "banner") will be recorded and
       included in the status message.

       The full set of commands available for the bb-services file are:

       [NAME] Define  the  name  of  the  TCP service, which will also be the column-name in the resulting display on the test status. If multiple
	      tests share a common definition (e.g. ssh, ssh1 and ssh2 are tested identically), you may list these in a  single  "[ssh|ssh1|ssh2]"
	      definition, separating each service-name with a pipe-sign.

       send STRING

       expect STRING
	      Defines the strings to send to the service after a connection is established, and the response that is expected. Either of these may
	      be omitted, in which case bbtest-net(1) will simply not send any data, or match a response against anything.

	      The send- and expect-strings use standard escaping for non-printable characters. "
" represents a carriage-return (ASCII 13),  "
"
	      represents  a  line-feed	(ASCII 10), "	" represents a TAB (ASCII 8).  Binary data is input as "xNN" with NN being the hexadecimal
	      value of the byte.

       port NUMBER
	      Define the default TCP port-number for this service. If no portnumber is defined, bbtest-net(1) will attempt to lookup the  portnum-
	      ber in the standard /etc/services file.

       options option1[,option2][,option3]
	      Defines test options. The possible options are
		 banner - include received data in the status message
		 ssl - service uses SSL so perform an SSL handshake
		 telnet - service is telnet, so exchange telnet options

FILES

       $BBHOME/etc/bb-services
