Wrench ksh script trying to pass a variable to edit a file
I'm trying to create a ksh script that will ask the user for the port number. $PORT1 is the variable I want to use that will contain whatever numbers the user inputs. The script would edit ports.txt file, search and delete "./serv 110.1.0.1.$PORT1 200;=3" .

So if the user types 50243 then the script would search and delete "./serv 110.1.0.1.50243 200;=3" so far no luck on accomplishing this. Please help

This is what I have so far:
Code:
printf "Enter port to be removed from monitoring: "
read PORT1

ex /home/user/ports.txt <<"EOF" > /dev/null 2>&1
%s!"./serv 110.1.0.1.$PORT1 200;=3"!!g
w
q
EOF

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words,  following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
	   able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation  are  not
	   performed.
