Checking for substring in a loop takes too long to complete.
I need to check if the files returned by ls command in the below script is a sub-string of the argument passed to the script i.e $1
The below script works fine but is too slow.
If the ls command take 12 secs to complete printing all files with while loop then; using posix substring check with grep -q in the script increases the total time to about 140 seconds.
If there a way to optimize the script for quicker results ?

LEARN ABOUT PHP
ignore_user_abort
IGNORE_USER_ABORT(3) 1 IGNORE_USER_ABORT(3)ignore_user_abort - Set whether a client disconnect should abort script executionSYNOPSIS
int ignore_user_abort ([string $value])
DESCRIPTION
Sets whether a client disconnect should cause a script to be aborted.
When running PHP as a command line script, and the script's tty goes away without the script being terminated then the script will die the
next time it tries to write anything, unless $value is set to TRUE
PARAMETERS
o $value
- If set, this function will set the ignore_user_abort ini setting to the given $value. If not, this function will only return the
previous setting without changing it.
RETURN VALUES
Returns the previous setting, as an integer.
EXAMPLES
Example #1
A ignore_user_abort(3) example
<?php
// Ignore user aborts and allow the script
// to run forever
ignore_user_abort(true);
set_time_limit(0);
echo 'Testing connection handling in PHP';
// Run a pointless loop that sometime
// hopefully will make us click away from
// page or click the "Stop" button.
while(1)
{
// Did the connection fail?
if(connection_status() != CONNECTION_NORMAL)
{
break;
}
// Sleep for 10 seconds
sleep(10);
}
// If this is reached, then the 'break'
// was triggered from inside the while loop
// So here we can log, or perform any other tasks
// we need without actually being dependent on the
// browser.
?>
NOTES
PHP will not detect that the user has aborted the connection until an attempt is made to send information to the client. Simply using an
echo statement does not guarantee that information is sent, see flush(3).
SEE ALSO connection_aborted(3), connection_status(3), Connection Handling for a complete description of connection handling in PHP. .
