title: IF statement in Batch Script
body: <p>I'm writing a batch script that switches between ip addresses depending on the users input.
  The core functionality of the script works however I want to add some checks into each function to check which setting is already applied and give a response accordingly.</p>
  
  <p>My current code is:</p>
  
  <pre><code>@ECHO OFF
  ::Change Static IP address for simulator or network connection
  
  :MAINMENU choose option from menu
  ::Set Current IP Address
  
  for /F "tokens=2 delims=:" %%i in ('"ipconfig | findstr IP | findstr 192."') do SET LOCAL_IP=%%i
  
  ECHO.
  ECHO. Set Workstation...........1
  ECHO. Set Simulator.............2
  ECHO. Quit (no further action)..Q
  ECHO.
  choice /c:Q21
  ECHO.
  
  IF ERRORLEVEL 3 GOTO WORK
  IF ERRORLEVEL 2 GOTO SIM
  IF ERRORLEVEL 1 GOTO EOF
  
  ::Change IP To network settings
  :WORK
  IF "LOCAL_IP"=="192.168.1.4" (
  ECHO. You are already in this mode
  GOTO MAINMENU 
  ) ELSE
  (echo "Setting Static IP Information" 
  netsh int ip set address name="Local Area Connection" source=static addr=192.168.1.4 mask=255.255.255.0 gateway=192.168.1.254 gwmetric=1 
  netsh int ip set dns name="Local Area Connection" source=static addr=192.168.1.1
  
  echo IP Address Set
  goto MAINMENU)
  
  ::Set Simulator IP Address
  :SIM
  IF "LOCAL_IP"=="192.168.4.1" (
  ECHO. You are already in this mode
  GOTO MAINMENU
  ) ELSE
  echo "Setting Static IP Information"
  netsh int ip set address name="Local Area Connection" source=dhcp
  netsh int ip set dns name="Local Area Connection" source=dhcp
  netsh int ip set address name="Local Area Connection" source=static addr=192.168.4.1 mask=255.255.255.0
  echo "Setting Static IP Information"
  goto MAINMENU
  
  :EOF
  pause
  </code></pre>
  
  <p>I'm having trouble getting the IF statement to compare the current IP address with the one i want to set it to.
  Can anybody suggest where I am going wrong or offer some ideas to get this working please?</p>
