No we can't because you enclosed your script in angle brackets.

Anyway, change your script (looks like PHP?) to:
Code:
<?
$command="ping linux.com -t  ttl -c1 | tail -1 | awk '{print \"DATA: \" $4 \" \" $5}'";
system($command);
?>

You don't need the second system call, and you dont need to assign the output of the first to a variable unless you need to check that it succeeded (the output of your command is displayed automatically)

SET_TIME_LIMIT(3)							 1							 SET_TIME_LIMIT(3)

set_time_limit - Limits the maximum execution time

SYNOPSIS
bool set_time_limit (int $seconds) DESCRIPTION
Set the number of seconds a script is allowed to run. If this is reached, the script returns a fatal error. The default limit is 30 sec- onds or, if it exists, the max_execution_time value defined in the php.ini. When called, set_time_limit(3) restarts the timeout counter from zero. In other words, if the timeout is the default 30 seconds, and 25 seconds into script execution a call such as set_time_limit(20) is made, the script will run for a total of 45 seconds before timing out. PARAMETERS
o $seconds - The maximum execution time, in seconds. If set to zero, no time limit is imposed. RETURN VALUES
Returns TRUE on success, or FALSE on failure. NOTES
Warning This function has no effect when PHP is running in safe mode. There is no workaround other than turning off safe mode or changing the time limit in the php.ini. Note The set_time_limit(3) function and the configuration directive max_execution_time only affect the execution time of the script itself. Any time spent on activity that happens outside the execution of the script such as system calls using system(3), stream operations, database queries, etc. is not included when determining the maximum time that the script has been running. This is not true on Windows where the measured time is real. SEE ALSO
