Instead of ".", which is short for "the currect directory" use a real path. You can even put this into a variable like you did with the archiving time. For instance:
I'm trying to find the 50 largest file in a directory named /sasdb and its' subdirectories. I'm using the find command and a pipe to awk

Hello all,
I am having a hard type in figuring out how to only gather certain files in the current directory without exploring its subdirectories.
I tried:
find . -name "*.ksh" -prune
this also returns ksh files from lower subdirectories.
I also tried
find . -ls -name "*.ksh"

Find all files in the current directory only excluding hidden directories and files.
For the below command, though it's not deleting hidden files.. it is traversing through the hidden directories and listing normal which should be avoided.

Thanks,

Plack::Builder(3pm) User Contributed Perl Documentation Plack::Builder(3pm)NAME
Plack::Builder - OO and DSL to enable Plack Middlewares
SYNOPSIS
# in .psgi
use Plack::Builder;
my $app = sub { ... };
builder {
enable "Deflater";
enable "Session", store => "File";
enable "Debug", panels => [ qw(DBITrace Memory Timer) ];
enable "+My::Plack::Middleware";
$app;
};
# use URLMap
builder {
mount "/foo" => builder {
enable "Foo";
$app;
};
mount "/bar" => $app2;
mount "http://example.com/" => builder { $app3 };
};
# using OO interface
my $builder = Plack::Builder->new();
$builder->add_middleware('Foo', opt => 1);
$app = $builder->mount('/app' => $app);
$app = $builder->to_app($app);
DESCRIPTION
Plack::Builder gives you a quick domain specific language (DSL) to wrap your application with Plack::Middleware subclasses. The middleware
you're trying to use should use Plack::Middleware as a base class to use this DSL, inspired by Rack::Builder.
Whenever you call "enable" on any middleware, the middleware app is pushed to the stack inside the builder, and then reversed when it
actually creates a wrapped application handler. "Plack::Middleware::" is added as a prefix by default. So:
builder {
enable "Foo";
enable "Bar", opt => "val";
$app;
};
is syntactically equal to:
$app = Plack::Middleware::Bar->wrap($app, opt => "val");
$app = Plack::Middleware::Foo->wrap($app);
In other words, you're supposed to "enable" middleware from outer to inner.
INLINE MIDDLEWARE
Plack::Builder allows you to code middleware inline using a nested code reference.
If the first argument to "enable" is a code reference, it will be passed an $app and is supposed to return another code reference which is
PSGI application that consumes $env in runtime. So:
builder {
enable sub {
my $app = shift;
sub {
my $env = shift;
# do preprocessing
my $res = $app->($env);
# do postprocessing
return $res;
};
};
$app;
};
is equal to:
my $mw = sub {
my $app = shift;
sub { my $env = shift; $app->($env) };
};
$app = $mw->($app);
URLMap support
Plack::Builder has a native support for Plack::App::URLMap with "mount" method.
use Plack::Builder;
my $app = builder {
mount "/foo" => $app1;
mount "/bar" => builder {
enable "Foo";
$app2;
};
};
See Plack::App::URLMap's "map" method to see what they mean. With builder you can't use "map" as a DSL, for the obvious reason :)
NOTE: Once you use "mount" in your builder code, you have to use "mount" for all the paths, including the root path ("/"). You can't have
the default app in the last line of "builder" like:
my $app = sub {
my $env = shift;
...
};
builder {
mount "/foo" => sub { ... };
$app; # THIS DOESN'T WORK
};
You'll get warnings saying that your mount configuration will be ignored. Instead you should use "mount "/" => ..." in the last line to set
the default fallback app.
builder {
mount "/foo" => sub { ... };
mount "/" => $app;
}
Note that the "builder" DSL returns a whole new PSGI application, which means
o "builder { ... }" should normally the last statement of a ".psgi" file, because the return value of "builder" is the application that
actually is executed.
o You can nest your "builder" block, mixed with "mount" (see URLMap support above):
builder {
mount "/foo" => builder {
mount "/bar" => $app;
}
}
will locate the $app under "/foo/bar" since the inner "builder" block puts it under "/bar" and it results a new PSGI application which
is located under "/foo" because of the outer "builder" block.
CONDITIONAL MIDDLEWARE SUPPORT
You can use "enable_if" to conditionally enable middleware based on the runtime environment. See Plack::Middleware::Conditional for
details.
