For ex:
awk '$1=="174" { ppid=($2) ; sed -n '/$ppid/p' tempfind.txt ; }' tempfind.txt
Assume: 174 is string.
Assume: tempfind.txt is used for awk and sed both.

output would be:

I'm thinking that AWK would be the easiest way to do this... Currently looking it up.

statistics::basic::covariance
Statistics::Basic::Covariance(3pm) User Contributed Perl Documentation Statistics::Basic::Covariance(3pm)NAME
Statistics::Basic::Covariance - find the covariance between two lists
SYNOPSIS
Invoke it this way:
my $covariance = covariance( [1,2,3], [1,2,3] );
Or this way:
my $v1 = vector(1,2,3);
my $v2 = vector(1,2,3);
my $cov = cov($v1,$v2);
And then either query the values or print them like so:
print "The covariance between $v1 and $v2: $covariance
";
my $cq = $cov->query;
my $c0 = 0+$cov;
Create a 20 point "moving" covariance like so:
use Statistics::Basic qw(:all nofill);
my $sth = $dbh->prepare("select col1,col2 from data where something");
my $len = 20;
my $cov = cov();
$cov->set_size($len);
$sth->execute or die $dbh->errstr;
$sth->bind_columns( my ($lhs, $rhs) ) or die $dbh->errstr;
my $count = $len;
while( $sth->fetch ) {
$cov->insert( $lhs, $rhs );
if( defined( my $c = $cov->query ) ) {
print "Covariance: $c
";
}
# This would also work:
# print "Covariance: $cov
" if $cov->query_filled;
}
METHODS
This list of methods skips the methods inherited from Statistics::Basic::_TwoVectorBase (things like query(), insert(), and ginsert()).
new()
Create a new Statistics::Basic::Covariance object. This function takes two arguments -- which can either be arrayrefs or
Statistics::Basic::Vector objects. This function is called when the covariance() shortcut-function is called.
query_vector1()
Return the Statistics::Basic::Vector for the first vector.
query_vector2()
Return the Statistics::Basic::Vector object for the second vector.
query_mean1()
Returns the Statistics::Basic::Mean object for the first vector.
query_mean2()
Returns the Statistics::Basic::Mean object for the second vector.
OVERLOADS
This object is overloaded. It tries to return an appropriate string for the calculation or the value of the computation in numeric
context.
In boolean context, this object is always true (even when empty).
