 2.6 Command-line options :h4,link(2_6)
 
 At run time, LAMMPS recognizes several optional command-line switches

 Specify a variable that will be defined for substitution purposes when
 the input script is read.  "Name" is the variable name which can be a
 single character (referenced as $x in the input script) or a full
-string (referenced as $\{abc\}).  The value can be any string.  Using
-this command-line option is equivalent to putting the line "variable
-name index value" at the beginning of the input script.  Defining an
-index variable as a command-line argument overrides any setting for
-the same index variable in the input script, since index variables
-cannot be re-defined.  See the "variable"_variable.html command for
-more info on defining index and other kinds of variables and "this
