In this below example, I want to transfer the output of one file to the
other file
for reading and then take the average of every column. Do you have any
idea about why column_average function doesn't works when multiple files
Are passed using the for routine?
#!/usr/bin/perl -w
use fileoprn

...
sub column_average {
my ($idx) = @_;
my $sum = sum map {$_-[$idx] if defined $_-[$idx]} @data;
return $sum;
}
This
system(qq~agrep $fir\t$sec\t $outfile tmp~); ## agrep is an external
utility to find search pattern in a file and transfer it into other file.
system(qq~agrep $thr tmp tmp1~); ## agrep is more faster than regular
expression.
Are two system calls to agrep really faster than a single,
Actually Regex is taking more time instead of agrep. That's why the idea
of using either agrep or find.
This is small input.txt which I am using it as a input file.
If there is any other way of increasing the speed of same Perl script,
it is really required.
Thanks,
Seema.

What's the difference? Several times? Twice? A bit? I haven't been paying
attention, so pardon if I missed something. For each invocation

I don't have agrep but since

You can reduce the speed by: 1) running on a slower machine, 2) running
other compute-intensive programs at the same time, or 3)
U had me confused. I thought u wanted to make this run slower because it
was bogging down ur computer or something. But based on ur script comments
and other posts it seems u want to make it run faster. So u want to reduce
the time of execution not the speed of execution.
