Hi guys. I need to filter some values from a number of log files. One of the files is:
Code:
Interconnect Utilisation Results:
Achieved Maximum Number of Concurrent Connections: 17
Statistics for Average Number of Concurrent Connections:
Point Estimation: Confidence Interval: Confidence Level: Relative Error: Accurate:
14.9346345 [14.80390583, 15.06536317] 0.95 0.008830687741 true
Buffer Memory Results:
Maximum Occupation: 45077
Statistics for Average Occupation:
Point Estimation: Confidence Interval: Confidence Level: Relative Error: Accurate:
34874.71178 [34589.93293, 35159.49063] 0.95 0.008232998013 true
From this file i need to get the values:
- 14.9346345
- true
- 34874.71178
- true
The other log files are the same so if i can solve this problem i'll be fine
Anyone has any ideas how i can get these in separate variables with grep / awk?

I have few of questions related to Grep given below:
1. Like Perl, is it possible in Grep to negate characters in square brackets. For example in Perl, if '^' is used inside '' then it acts as a negation characters. Can same be achieved through Grep's regular expression.

statistics::basic::correlation
Statistics::Basic::Correlation(3pm) User Contributed Perl Documentation Statistics::Basic::Correlation(3pm)NAME
Statistics::Basic::Correlation - find the correlation between two lists
SYNOPSIS
Invoke it this way:
my $correlation = correlation( [1,2,3], [1,2,3] );
Or this way:
my $v1 = vector(1,2,3);
my $v2 = vector(1,2,3);
my $cor = corr($v1,$v2);
And then either query the values or print them like so:
print "The correlation between $v1 and $v2: $correlation
";
my $cq = $cor->query;
my $c0 = 0+$correlation;
Create a 20 point "moving" correlation like so:
use Statistics::Basic qw(:all nofill);
my $sth = $dbh->prepare("select col1,col2 from data where something");
my $len = 20;
my $cor = corr()->set_size($len);
$sth->execute or die $dbh->errstr;
$sth->bind_columns( my ($lhs, $rhs) ) or die $dbh->errstr;
my $count = $len;
while( $sth->fetch ) {
$cor->insert( $lhs, $rhs );
if( defined( my $c = $cor->query ) ) {
print "Correlation: $c
";
}
# This would also work:
# print "Correlation: $cor
" if $cor->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::Correlation object. This function takes two arguments -- which can either be arrayrefs or
Statistics::Basic::Vector objects. This function is called when the correlation() shortcut-function is called.
query_covariance()
Returns the Statistics::Basic::Covariance object used to calculate the correlation.
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).
