mysql command line return execution time?

Question

I\'m working on a Linux host with mysql command. I have a script that runs batch mysql commands (like mysql -e \"select...\") and I wish to summarize execution time

Here is the exact syntax for PHP.

mysql_query("SET profiling = 1;");
if (mysql_errno()) { die( "ERROR ".mysql_errno($link) . ": " . mysql_error($link) ); }

$query="SELECT some_field_name FROM some_table_name";
$result = mysql_query($query);
if (mysql_errno()) { die( "ERROR ".mysql_errno($link) . ": " . mysql_error($link) ); }

$exec_time_result=mysql_query("SELECT query_id, SUM(duration) FROM information_schema.profiling GROUP BY query_id ORDER BY query_id DESC LIMIT 1;");
if (mysql_errno()) { die( "ERROR ".mysql_errno($link) . ": " . mysql_error($link) ); }
$exec_time_row = mysql_fetch_array($exec_time_result);

echo "
Query executed in ".$exec_time_row[1].' seconds';
