Based on the discussion and clues you all have given, I have solved the issue :-) What I have done [1] scp a copy of .screenrc to remote server [2] ssh to the remote box and start screen [3] rm the .screnrc before logout. All these are automated with expect script. Here is the code I am using in my ssh manager script ` ` ` expect -c ' #for debug #exp_internal 1 log_user 0 #Placed .screenrc on the remote server spawn scp "/home/admin/.screenrc" '$ssh_Server':'$screenrc_location' expect "*assword:" send '$PASSWORD' send "\r" interact #start screen through ssh on remote server spawn ssh '$ssh_Server' -t LANG=en_US.UTF-8 && TERM=xterm && "screen -c '$screenrc_location' -aUS '$ssh_Server' -dR bash -l ||ssh '$ssh_Server'" expect "*assword:" send '$PASSWORD' send "\r" interact #Delete .screenrc before logout spawn ssh '$ssh_Server' rm -f '$screenrc_location' expect "*assword:" send '$PASSWORD' send "\r" interact ' ` ` ` Hope this is helpful. Todo - checking if screen is installed in the remote server before scp ; if not then give a warning and exit.
