Comparing Variables in strings

I have 2 variables $newSize & $oldSize.  Each variable holds a single number corresponding to the line count of a certain file.  If $newSize is less than $oldSize, I want it to do something.  What is the syntax to put this in an If statement?

Thanx

which shell are you using ?

  1. for sh, ksh, bash, use:

  if [ $newSize  -lt $oldSize ] ; then

      your-action-here

  fi

 
  2. For csh/tcsh using

   if ( $newSize  < $oldSize ) then
      your-action-here
   endif
