How to print out with equal spacing between columns?
For instance, my file contains the following content...
Code:
set -A array
set -A test
${array[0]}=1
${array[1]}=2
${array[2]}=3
${test[0]}="Boy"
${test[1]}="Girl"
${test[2]}="Dog"
x=0
while [ $x -lt 3 ];do
print "${array[$x]}" " " "${test[$x]}"
x=$((x+1)
done
As you can I have to manually control the spacing between the printing of the columns....I think I saw like
Friends,
I have very large data files (File1 and File2).
Search field1 of File1 into Field1 of File2.
If found then do Field1 of File1 MINUS Field1 of File2
if the answer is <= 0.003 (positive or negative) then
print that line from File1.

catch signal SIGPIPE ,print errno but it's value equal to 2(ENOENT)
#define ENOENT 2 /* No such file or directory */
is it should be EPIPE ?
#define EPIPE 32 /* Broken pipe */

Hi,
I am writing this script to find all files in a directory and print the filepath, date and file size.
However, it doesnt seem to preserve double spacing file with this script. I would appreciate a pointer or 2 to get around this -

Using awk, print all the lines where field 8 is equal to x
I really did try, but this awk thing is really hard to figure out.

Hi!
I need to change the spacing assigned to each number in a text file. I have an input file with 5 columns and 3 rows. Here, all numbers are separated by 1 space. I need to change this in such a way that the number in the first column has 6, the number in the second column has 5 and all other... (2 Replies)

Statistics::Test::RandomWalk(3pm) User Contributed Perl Documentation Statistics::Test::RandomWalk(3pm)NAME
Statistics::Test::RandomWalk - Random Walk test for random numbers
SYNOPSIS
use Statistics::Test::RandomWalk;
my $tester = Statistics::Test::RandomWalk->new();
$tester->set_data( [map {rand()} 1..1000000] );
my $no_bins = 10;
my ($quant, $got, $expected) = $tester->test($no_bins);
print $tester->data_to_report($quant, $got, $expected);
DESCRIPTION
This module implements a Random Walk test of a random number generator as outlined in Blobel et al (Refer to the SEE ALSO section).
Basically, it tests that the numbers "[0,1]" generated by a random number generator are distributed evenly. It divides "[0,1]" into "n"
evenly sized bins and calculates the number of expected and actual random numbers in the bin. (In fact, this counts the cumulated numbers,
but that works the same.)
METHODS
new
Creates a new random number tester.
set_rescale_factor
The default range of the random numbers [0, 1) can be rescaled by a constant factor. This method is the setter for that factor.
rescale_factor
Returns the current rescaling factor.
set_data
Sets the random numbers to operate on. First argument must be either an array reference to an array of random numbers or a code reference.
If the first argument is a code reference, the second argument must be an integer "n". The code reference is called "n"-times and its
return values are used as random numbers.
The code reference semantics are particularly useful if you do not want to store all random numbers in memory at the same time. You can
write a subroutine that, for example, generates and returns batches of 100 random numbers so no more than 101 of these numbers will be in
memory at the same time. Note that if you return 100 numbers at once and pass in "n=50", you will have a sequence of 5000 random numbers.
test
Runs the Random Walk test on the data that was previously set using "set_data".
First argument must be the number of bins.
Returns three array references. First is an array of quantiles. If the number of bins was ten, this (and all other returned arrays) will
hold ten items.
Second are the determined numbers of random numbers below the quantiles. Third are the expected counts.
data_to_report
From the data returned by the "test()" method, this method creates a textual report and returns it as a string.
Do not forget to pass in the data that was returned by "test()" or use the "test_report()" method directly if you do not use the data
otherwise.
SUBROUTINES
n_over_k
Computes "n" over "k". Uses Perl's big number support and returns a Math::BigFloat object.
This sub is memoized.
