Perl : print the sequence number without missing number
Dear Perl users,
I need your help to solve my problem below.
I want to print the sequence number without missing number within the range.
E.g. my sequence number :
Dear Perl's Users,
Could anyone help me how to solve my problem. I have data with details below.

Hello all,
I have several directories with a sequence of files like this
IM-0001-0001.dcm
IM-0001-0002.dcm
IM-0001-0003.dcm
IM-0001-0004.dcm
IM-0001-0005.dcm
I would like to print out the name of the file that is missing.
I currently have the following ineffecient way to do this... (4 Replies)
I would like to print the number of records of 2 files, and divide the two numbers
awk '{print NR}' file1 > output1
awk '{print NR}' file2 > output2
paste output1 output2 > output
awl '{print $1/$2}' output > output_2
is there a faster way? (8 Replies)

Hi
I want to use awk to match where field 3 contains a number within string - then print the line and just the number as a new field.
The source file is pipe delimited and looks something like

1|net|EXP_1040 ABC|1121|||

Hi,
In an ideal scenario, I will have a listing of db transaction log that gets copied to a DR site and if I have them all, they will be numbered consecutively like below.

I have a directory of files, I can show the number of lines in each file and order them from lowest to highest with:
wc -l *|sort

How can I also print the number of unique lines in each file?

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.
