Hi there, I have a csv file with some columns comma sepated like this :
4502-17,PETER,ITA2,LEGUE,92,ME - HALF,23/05/10 15:00
4502-18,CARL,ITA2,LEGUE,96,ME - HALF,20/01/09 14:00
4502-19,OTTO,ITA2,LEGUE,97,ME - MARY,23/05/10 15:00
As you can see the column n. 7 is a timestamp column, I need... (23 Replies)
Hi Everyone,
a.txt
a b c 1 e e e e e
a b c 2 e e e e e
the output is
a b c 1 e e e e e
a 00b c 2 e e e e e
when 4th field = '2', then add '00' in the front of 2nd field value.
Thanks (9 Replies)
Dear All,
I would like to add values of a field, if the lines match in a certain field. Then I would like to divide the sum though the number of lines that have a matched field. This is the Input:
Input:
Test1 5
Test1 10
Test2 2
Test2 5
Test2 13
Test3 4
Output:
Test1 7.5

In file1 field $18 is removed.... column header is "Otherinfo", then each line in file1 is used to search file2 for a match. When a match is found the last four strings in file2 are copied to file1.
Maybe:
cut -f1-17 file1 and then match each line to file2

The awk below does put in VUS in the 9th field but I can not seem to skip the header then add the VUS. I tried to incorporate NR >=2 and NR > 1 with no luck. Thank you :).

Trying to use awk to add a . to $4. The input and output is tab-delimeted, but the awk seems to add a . in front of $5 and is space-delimeted. It seems close, but I am not able to produce the desired output. Thank you :).

In the tab-delimited input below I am trying to use awk to -10 from $2 and +10 to $3. Something like
awk -F'\t' -v OFS='\t' -v s=10 '{split($4,a,":"); print $1,$2-s,$3+s,a,$5,$6} | awk {split(a,b,"-"); print $1,$2-s,$3+s,b-s,b+s,$5,$6}' input
should do that. I also need to -10 from $4... (2 Replies)
In the awk I am trying to add :p.=? to the end of each $9 that matches the pattern NM_. The below executes andis close but I can not seem to figure out why the :p.=? repeats in the split as in the green in the current output. I have added comments as well. Thank you :).

The awk below produces the current output, which will add +1 to $3. However, I am trying to add the length of the matching characters between $5 and $6 to $3.

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.
