4.4.4 Header data records: The <B>-H</B> option</A>
</H2>
<A NAME="18665"></A>
<A NAME="18666"></A>
<A NAME="sec:header"></A>The <B>-H</B>[<B>i</B>][<I>n_recs</I>] option lets <A NAME="tex2html1129"
  HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> know that input file(s) have
one [Default] or more header records.  If there are more than one header
record you must specify the number after the <B>-H</B> option, e.g., <B>-H</B>4.  The
default number of header records if <B>-H</B> is used is one of the many parameters
in the <U>.gmtdefaults4</U> file (<B>N_HEADER_RECS</B>), but can be overridden
by <B>-H</B><I>n_header_recs</I>.
Note that blank lines and records that be start with the character # are
automatically skipped.  Normally, programs that both read and write tables will
output the header records that are found on input.  Use <B>-Hi</B> to suppress the
writing of header records.
