Hi,
I have created a tab separated file from the following input file.
As I was only interested in columns 1,2,4 and 5 and i wanted to reorganize it, I used the following awk command.
The above code has created the following output file.
However, when i open this file with excel on Windows and i specify it is a tab delimited file, The complete row is shown as a single column. Whereas in UNIX when i check this file with the following command It shows that there are 4 columns.
Am I missing something, how to fix this. I use the output file as an input to some java program, I tried debugging the java program and found out that the total row is considered as a single column, instead of 4 columns
Hello,
I am trying to parse a file that resembles the last three groupings into something looking like the first two lines. I've fiddled with sed and awk a bit, but can't get anything to work properly. I need them separated by some delimiter. The file is some 23,000 lines of the stuff....

Dear users,
I have this problem, this is the example:
123 (tab) A (tab) B (tab) C (tab) 456
where the (tab) is actually the \t delimiter. I need to replace the A B and C for D E and F, this is:
123 (tab) D (tab) E (tab) F (tab) 456
The thing is that my file is quite long and this... (2 Replies)

Hi all,
I'm trying to read a tab separated file and apply some functions on each column. I have an issue with empty column.

In the gawk below, I am trying to output the file tab-deliminated but don't think that is the correct syntax. Thank you :).

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.
