Hi,
I'm trying to write a function that redirects the contents of an
array to a file. The array contains the lines of a data file with
white space.
The function seems to preserve all white space when redirected
except that it seems to ignore newlines. As a consequence, the
elements of the... (7 Replies)
Hi Guys,
I have a file which has numbers in it separated by newlines as follows:
1.113
1.456
0.556
0.021
-0.541
-0.444
I am using the following code to store these in an array in bash:
FILE14=data.txt
ARRAY14=(`awk '{print}' $FILE14`) (6 Replies)
I have one file "file.a.b.c-d.r" that I would like to use to spawn 4 other files:

"file.a.b.1-C.r"
"file.a.b.1-D.r"
where the field "c-d" changes into my 1 and A-D.
I was doing this manually at the prompt with

I have figured out how to grep the file like this:
echo `grep $(date +'%Y-%m-%d') Cos-01.csv | cut -d',' -f1`
The above line does echo the correct information from the lines in which my search criteria is found.
Now I am trying to get that information (Yes, just one column of every line) into... (6 Replies)

Hi,
I'm trying to write a bash script that takes a file and passes each line from the file into an array with elements separated by column.
For example:
Sample file "file1.txt":
1 name1 a first
2 name2 b second
3 name3 c third
and have arrays such as:
line1 = ( "1" "name1" "a"... (3 Replies)
for a in {1..100}
do
awk '{ sum+=$a} END {print sum}' a=$a file1 > file2
done
I know I will get only one number if following the code above, how can I get 100 sum numbers in file2? (2 Replies)

Tree::Simple::Visitor::ToNestedArray(3pm) User Contributed Perl Documentation Tree::Simple::Visitor::ToNestedArray(3pm)NAME
Tree::Simple::Visitor::ToNestedArray - A Visitor for creating nested array trees from Tree::Simple objects.
SYNOPSIS
use Tree::Simple::Visitor::ToNestedArray;
my $visitor = Tree::Simple::Visitor::ToNestedArray->new();
# given this Tree::Simple tree
my $tree = Tree::Simple->new("Root")
->addChildren(
Tree::Simple->new("Child1")
->addChildren(
Tree::Simple->new("GrandChild1"),
Tree::Simple->new("GrandChild2")
),
Tree::Simple->new("Child2"),
);
# include the trunk (Root)
$visitor->includeTrunk(1);
# visit the tree
$tree->accept($visitor);
my $array_tree = $visitor->getResults();
# this then creates the equivalent nested array tree:
# [
# 'Root', [
# 'Child1', [
# 'GrandChild1',
# 'GrandChild2'
# ],
# 'Child2'
# ]
# ]
# if you don't include the trunk (Root) then ...
$tree->accept($visitor);
my $array_tree = $visitor->getResults();
# this then creates the following nested array tree:
# [
# 'Child1', [
# 'GrandChild1',
# 'GrandChild2'
# ],
# 'Child2'
# ]
DESCRIPTION
Given a tree constructed from a Tree::Simple heirarchy, this Visitor will create the equivalent tree of nested arrays.
METHODS
new There are no arguments to the constructor the object will be in its default state. You can use the "setNodeFilter" and "includTrunk"
methods to customize its behavior.
includTrunk ($boolean)
Setting the $boolean value to true(1) will cause the node value of the tree's root to be included in the nested array output, setting
it to false will do the opposite.
setNodeFilter ($filter_function)
This method accepts a CODE reference as its $filter_function argument and throws an exception if it is not a code reference. This code
reference is used to filter the tree nodes as they are placed into the array tree. The $filter_function is passed a Tree::Simple
object, and is expected to return the value desired for inclusion into the array tree.
visit ($tree)
This is the method that is used by Tree::Simple's "accept" method. It can also be used on its own, it requires the $tree argument to be
a Tree::Simple object (or derived from a Tree::Simple object), and will throw and exception otherwise.
getResults
This method will return the array tree constructed.
BUGS
None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to fix it.
CODE COVERAGE
See the CODE COVERAGE section in Tree::Simple::VisitorFactory for more inforamtion.
SEE ALSO
These Visitor classes are all subclasses of Tree::Simple::Visitor, which can be found in the Tree::Simple module, you should refer to that
module for more information.
