Hi--
Ok. I have now found that:
find -x -ls
will do what I need as far as finding all files on a particular volume. Now I need to sort the results by the file's modification date/time.
Is there a way to do that?
Also, I notice that for many files, whereas the man for find says ls is... (8 Replies)

Hi,
I have a problem with a shell script.

Hey,
I am writing a script to delete log files that are older than one day (I'm going to run it weekly). Basically, it should work so that it only keeps the current day, but keeping the previous day as well isn't a dealbreaker.
I am running the following line on the files listed below:

Hello and thanks in advance for any help anyone can offer me

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.
