<H4><A NAME = "2_6"></A>2.6 Command-line options

<P>At run time, LAMMPS recognizes several optional command-line switches
which may be used in any order. For example, lmp_ibm might be
launched as follows:
which may be used in any order. Either the full word or the
one-letter abbreviation can be used:

<P>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 <A HREF = "variable.html">variable</A> command for
more info on defining index and other kinds of variables and <A HREF = "Section_commands.html#3_2">this
string (referenced as ${abc}). An <A HREF = "variable.html">index-style
variable</A> will be created and populated with the
subsequent values, e.g. a set of filenames. Using this command-line
option is equivalent to putting the line "variable name index value1
value2 ..." 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 <A HREF = "variable.html">variable</A> command for more info on
defining index and other kinds of variables and <A HREF = "Section_commands.html#3_2">this
section</A> for more info on using variables in
input scripts.
