I have the following script:
Now they have added on a new requirement, they only want to go to a certain depth in the directories returned. How do I code it to only go say 3 directories deeper than $DIRECTORY? (12 Replies)
Hello,
I am looking for specific files in my tree directory using ftw(3). How do I know how deep I am in the file structure.. in other words, say I am looking for config.txt files, and my structure looks like this..
/some/directory/user1/config.txt
/some/directory/user2/config.txt

hello,
i want to use "-depth" in command "find" and want to exclude a directory.
the find command should work in HP-UX and Linux.
i see in the find man page:
-prune
If -depth is not given, true; do not descend the current directory.
If -depth is given, false; no effect.

I was looking at a code and stumbled over the option -depth of find command
After searching what -depth does I found the below:
-depth Process each directory's contents before the directory itself.
Does it mean the sub directories are processed before the current directory in the search... (1 Reply)
Hi
I am trying to a write a script which gives message queue depth for every 5 mins in a file.
Commands that I use are
runmqsc QM_Name
display ql(*) curdepth
Since I can use only MQSC commands I need help on how to fetch the output on to a file after executing display command. (3 Replies)
Hi All,
Can you please help me in understanding the importance of -depth of find.
I am trying to execute below code.find . -mtime +5 -name "*" -depth -exec ls -l {} \;
But it is throwing below error.find: warning: you have specified the -depth option after a non-option argument -mtime,... (2 Replies)
A few of our users are adept at creating folders like 2015\2015 something\event\2015 event\document\2015 which makes their documents close to impossible to find. Is there any way I can restrict the depth of the folders they are allowed to create? (1 Reply)

graph::unionfind
Graph::UnionFind(3pm) User Contributed Perl Documentation Graph::UnionFind(3pm)NAME
Graph::UnionFind - union-find data structures
SYNOPSIS
use Graph::UnionFind;
my $uf = Graph::UnionFind->new;
# Add the vertices to the data structure.
$uf->add($u);
$uf->add($v);
# Join the partitions of the vertices.
$uf->union( $u, $v );
# Find the partitions the vertices belong to
# in the union-find data structure. If they
# are equal, they are in the same partition.
# If the vertex has not been seen,
# undef is returned.
my $pu = $uf->find( $u );
my $pv = $uf->find( $v );
$uf->same($u, $v) # Equal to $pu eq $pv.
# Has the union-find seen this vertex?
$uf->has( $v )
DESCRIPTION
Union-find is a special data structure that can be used to track the partitioning of a set into subsets (a problem known also as disjoint
sets).
Graph::UnionFind() is used for Graph::connected_components(), Graph::connected_component(), and Graph::same_connected_components() if you
specify a true "union_find" parameter when you create an undirected graph.
Note that union-find is one way: you cannot (easily) 'ununion' vertices once you have 'unioned' them. This means that if you delete edges
from a "union_find" graph, you will get wrong results from the Graph::connected_components(), Graph::connected_component(), and
Graph::same_connected_components().
API
add
$uf->add($v)
Add the vertex v to the union-find.
union
$uf->union($u, $v)
Add the edge u-v to the union-find. Also implicitly adds the vertices.
has
$uf->has($v)
Return true if the vertex v has been added to the union-find, false otherwise.
find
$uf->find($v)
Return the union-find partition the vertex v belongs to, or "undef" if it has not been added.
new
$uf = Graph::UnionFind->new()
The constructor.
same
$uf->same($u, $v)
Return true of the vertices belong to the same union-find partition the vertex v belongs to, false otherwise.
