Parse using PHP's fscanf().
<lang php><?php
// make sure filename was specified on command line
if ( ! isset( $argv[1] ) )
die( 'Data file name required' );
// open file and check for success
if ( ! $fh = fopen( $argv[1], 'r' ) )
die ( 'Cannot open file: ' . $argv[1] );
while ( list( $date, $loc, $mag ) = fscanf( $fh, "%s %s %f\n" ) ) {
if ( $mag > 6 ) {
printf( "% -12s % -19s %.1f\n", $date, $loc, $mag );
}
}
fclose( $fh );
</lang>

<code>php eq.php data.txt</code>
