Hi,
I am new to UNIX and I am more used to simple commands like those in VMS.
One of them is the ability to get the output from a job using the /out=<file> command in VMS.
I want to submit a job (a set of unix commands) using the AT command but to get the output in a file like that used in... (4 Replies)

Hi All
I'm using a tree command in a script that for me outputs:-
| - - DIRECTORYNAME
However a different user is getting the following output:-
aaa (actually with an umlat above them) DIRECTORYNAME
I'm not sure where this could be coming from, any ideas anyone? (0 Replies)
Hi, I have this command:
ls -R | grep ":$" | sed -e 's/:$//' -e 's/*\//--/g' -e 's/^/ /' -e 's/-/|/' Works nicely to show the current file structure as a tree.
I'd like to have it as an alias in '' but doesn't work just like that and I can't fix it with backslashes:
alias tree='?'

Tree::Simple::Visitor::PreOrderTraversal(3pm) User Contributed Perl Documentation Tree::Simple::Visitor::PreOrderTraversal(3pm)NAME
Tree::Simple::Visitor::PreOrderTraversal - A Visitor for pre-order traversal a Tree::Simple hierarchy
SYNOPSIS
use Tree::Simple::Visitor::PreOrderTraversal;
# create an visitor
my $visitor = Tree::Simple::Visitor::PreOrderTraversal->new();
# pass our visitor to the tree
$tree->accept($visitor);
# print our results
print join ", " => $visitor->getResults();
# this will print this:
# 1 1.1 1.1.1 1.2 2 2.1 3 3.1
# assuming your tree is like this:
# 1
# 1.1
# 1.1.1
# 1.2
# 2
# 2.1
# 3
# 3.1
DESCRIPTION
Pre-order traversal is a depth-first traversal method in which the sub-tree's are processed after the parent. It is essentially a wrapper
around the base Tree::Simple::Visitor class, and is a separate module here for completeness. (If you have a post-order, you should have a
pre-order too).
METHODS
new There are no arguments to the constructor the object will be in its default state. You can use the "setNodeFilter" method to customize
its behavior.
includeTrunk ($boolean)
Based upon the value of $boolean, this will tell the visitor to include the trunk of the tree in the traversal as well.
setNodeFilter ($filter_function)
This method accepts a CODE reference as its $filter_function argument and throws an exception if it is not a code reference. This code
reference is used to filter the tree nodes as they are collected. This can be used to customize output, or to gather specific
information from a more complex tree node. The filter function should accept a single argument, which is the current Tree::Simple
object.
visit ($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 returns the accumulated results of the application of the node filter to the tree.
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.
