Hi,
I have one small doubt how to go ahead and process the below requirement.
File Content
Output file expected:
thousands of records
Note that the pqr is repeated 3 times in this case for the 3rd column we have the the 3rd column value of the 1st occurence of pqr copied for the 2nd and 3 occurenct
i.e 4,pqr,13 gets changed to 4,pqr,12
and 5,pqr,14 gets changed to 5,pqr,12
Once the output file is generated then
then i want something like
I want this to be done dynamically since the number of records might be in thousands atleast
Would appreciate if we can an awk solution for the same.
Regards,
Dikesh Shah

Hi guys,
I have found your forum super useful. However, right now I am stuck on a seemingly "simple" thing in AWK. I have two columns of data, the first column in Age (in million years) and the second column is Convergence Rate (in mm/yr).
I am trying to process my data so I can use it to... (2 Replies)

Hi! all
can any one tell me how to compare current record of column with next and previous record in awk without using array
my case is like this
input.txt
0 32
1 26
2 27
3 34
4 26
5 25
6 24
9 23
0 32
1 28

For example, I have a file called number.txt.
x y
1 1
2 4
3 9
4 6
5 5
6 6
7 9
8 4
9 1
10 0
...
And I want to print out the value of x and y, if y%4==0 and the next value of y%4==0. Thus, the sample output is:
1 1 *because the previous x before 2 is 1
2 4 *because 4%4 == 0

pdl::char
Char(3pm) User Contributed Perl Documentation Char(3pm)NAME
PDL::Char -- PDL subclass which allows reading and writing of fixed-length character strings as byte PDLs
SYNOPSIS
use PDL;
use PDL::Char;
my $pchar = PDL::Char->new( [['abc', 'def', 'ghi'],['jkl', 'mno', 'pqr']] );
$pchar->setstr(1,0,'foo');
print $pchar; # 'string' bound to "", perl stringify function
# Prints:
# [
# ['abc' 'foo' 'ghi']
# ['jkl' 'mno' 'pqr']
# ]
print $pchar->atstr(2,0);
# Prints:
# ghi
DESCRIPTION
This subclass of PDL allows one to manipulate PDLs of 'byte' type as if they were made of fixed length strings, not just numbers.
This type of behavior is useful when you want to work with charactar grids. The indexing is done on a string level and not a character
level for the 'setstr' and 'atstr' commands.
This module is in particular useful for writing NetCDF files that include character data using the PDL::NetCDF module.
FUNCTIONS
new
Function to create a byte PDL from a string, list of strings, list of list of strings, etc.
# create a new PDL::Char from a perl array of strings
$strpdl = PDL::Char->new( ['abc', 'def', 'ghij'] );
# Convert a PDL of type 'byte' to a PDL::Char
$strpdl1 = PDL::Char->new (sequence (byte, 4, 5)+99);
$pdlchar3d = PDL::Char->new([['abc','def','ghi'],['jkl', 'mno', 'pqr']]);
string
Function to print a character PDL (created by 'char') in a pretty format.
$char = PDL::Char->new( [['abc', 'def', 'ghi'], ['jkl', 'mno', 'pqr']] );
print $char; # 'string' bound to "", perl stringify function
# Prints:
# [
# ['abc' 'def' 'ghi']
# ['jkl' 'mno' 'pqr']
# ]
# 'string' is overloaded to the "" operator, so:
# print $char;
# should have the same effect.
setstr
Function to set one string value in a character PDL. The input position is the position of the string, not a character in the string. The
first dimension is assumed to be the length of the string.
The input string will be null-padded if the string is shorter than the first dimension of the PDL. It will be truncated if it is longer.
$char = PDL::Char->new( [['abc', 'def', 'ghi'], ['jkl', 'mno', 'pqr']] );
$char->setstr(0,1, 'foobar');
print $char; # 'string' bound to "", perl stringify function
# Prints:
# [
# ['abc' 'def' 'ghi']
# ['foo' 'mno' 'pqr']
# ]
$char->setstr(2,1, 'f');
print $char; # 'string' bound to "", perl stringify function
# Prints:
# [
# ['abc' 'def' 'ghi']
# ['foo' 'mno' 'f'] -> note that this 'f' is stored "f "
# ]
atstr
Function to fetch one string value from a PDL::Char type PDL, given a position within the PDL. The input position of the string, not a
character in the string. The length of the input string is the implied first dimension.
$char = PDL::Char->new( [['abc', 'def', 'ghi'], ['jkl', 'mno', 'pqr']] );
print $char->atstr(0,1);
# Prints:
# jkl
