I wrote this script with the help of you guyz.My next challenge is to increment the port using single file.So far iam using this code to increment hp1 and hp2 .To increment port numbers, iam using two different files (.default_port_hp1 and .default_port_hp2).The challenge for me is to use...

Hello,
Here's a file of mine:
key1:431
key2:159
key3:998
I need to change these keys to something bigger - and I actually need to shift them all by a range of 3.
The output would be:

key3:1001
I can't find the propper sed/awk line that would alter all my... (4 Replies)
Hello All,
In the below script i am trying to check and list the file names, get the last file with highest version number and then increment the version number when i create another file. Example: file1 is COBANK_v1.xml and file2 i want to put it as COBANK_v2.xml, to achieve this i am using awk... (15 Replies)
Two questions:
1) Is there a way to create a new column (i.e. ID) to an existing file containing data and the new column ID populate as an auto incrementing number?
for example:
(Current file has headers and is PIPE delimited.)
**data looks like this**
"COL1"|"COL2"|"COL3"|"COL4"|"COL5"... (0 Replies)
Hi,
This is my first post here.
I am using cygwin on Windows 7.
I am starting with a data file with filename "name_1.ext", like "20180831_snapgenotypes_1.csv".
The "_1" before ".ext" is a version number. Integers (0-99) are sufficient. They don't have to be like "1.0.0".
The filename may... (2 Replies)

devel::refcount
Devel::Refcount(3pm) User Contributed Perl Documentation Devel::Refcount(3pm)NAME
"Devel::Refcount" - obtain the REFCNT value of a referent
SYNOPSIS
use Devel::Refcount qw( refcount );
my $anon = [];
print "Anon ARRAY $anon has " . refcount($anon) . " reference
";
my $otherref = $anon;
print "Anon ARRAY $anon now has " . refcount($anon) . " references
";
DESCRIPTION
This module provides a single function which obtains the reference count of the object being pointed to by the passed reference value.
FUNCTIONS
$count = refcount($ref)
Returns the reference count of the object being pointed to by $ref.
COMPARISON WITH SvREFCNT
This function differs from "Devel::Peek::SvREFCNT" in that SvREFCNT() gives the reference count of the SV object itself that it is passed,
whereas refcount() gives the count of the object being pointed to. This allows it to give the count of any referent (i.e. ARRAY, HASH,
CODE, GLOB and Regexp types) as well.
Consider the following example program:
use Devel::Peek qw( SvREFCNT );
use Devel::Refcount qw( refcount );
sub printcount
{
my $name = shift;
printf "%30s has SvREFCNT=%d, refcount=%d
",
$name, SvREFCNT($_[0]), refcount($_[0]);
}
my $var = [];
printcount 'Initially, $var', $var;
my $othervar = $var;
printcount 'Before CODE ref, $var', $var;
printcount '$othervar', $othervar;
my $code = sub { undef $var };
printcount 'After CODE ref, $var', $var;
printcount '$othervar', $othervar;
This produces the output
Initially, $var has SvREFCNT=1, refcount=1
Before CODE ref, $var has SvREFCNT=1, refcount=2
$othervar has SvREFCNT=1, refcount=2
After CODE ref, $var has SvREFCNT=2, refcount=2
$othervar has SvREFCNT=1, refcount=2
Here, we see that SvREFCNT() counts the number of references to the SV object passed in as the scalar value - the $var or $othervar
respectively, whereas refcount() counts the number of reference values that point to the referent object - the anonymous ARRAY in this
case.
Before the CODE reference is constructed, both $var and $othervar have SvREFCNT() of 1, as they exist only in the current lexical pad. The
anonymous ARRAY has a refcount() of 2, because both $var and $othervar store a reference to it.
After the CODE reference is constructed, the $var variable now has an SvREFCNT() of 2, because it also appears in the lexical pad for the
new anonymous CODE block.
PURE-PERL FALLBACK
An XS implementation of this function is provided, and is used by default. If the XS library cannot be loaded, a fallback implementation in
pure perl using the "B" module is used instead. This will behave identically, but is much slower.
