Need to terminate the looping after reading the file contents!!!!!

[vijayarl]

Hi Everyone,

i have the written this logic :
basically a file operation

open (CONFIGFILE, "$config_file") or die;
 
while (<CONFIGFILE>) {    
    chomp;
 
    if ( ! ( $_ =~ /^#/ ) ) {
       $CONFIG = $CONFIG . $_ . " ";
    }
}
close (CONFIGFILE);
 

Note: Config file(text file) has some text lines<br>

now my problem is :
Config file has some 10 to 15 lines but the above code run for a while even after reading all the line from the file.

now i need some sort of logic where i can terminate the looping once it finishes the reading the line or it encounter the some specail character or keep some wait_time variable & loop till wait_time exceeds.

Can anyone help me on how to achieve above said logic ??

i need to alter this code to suit the above said requirement
can anyone help me on this ??

Regards,
Vijayarl

If you want to terminate the loop after a particular requirement is met, you may use the last statement.e.g

while(<FILE>) {
 if(/$pat/) {
  my $str= $_;
  last;  ## comes out of while loop
  }
}
