NAME

Filesys::DiskUsage - Estimate file space usage (similar to `du`)

SYNOPSIS

use Filesys::DiskUsage qw/du/;

# basic
$total = du(qw/file1 file2 directory1/);

or

# no recursion
$total = du( { recursive => 0 } , <*> );

or

# max-depth is 1
$total = du( { 'max-depth' => 1 } , <*> );

or

# get an array
@sizes = du( @files );

or

# get a hash
%sizes = du( { 'make-hash' => 1 }, @files_and_directories );

FUNCTIONS

du

Estimate file space usage.

Get the size of files:

$total = du(qw/file1 file2/);

Get the size of directories:

$total = du(qw/file1 directory1/);

OPTIONS

dereference

Follow symbolic links. Default is 0.

Get the size of a directory, recursively, following symbolic links:

$total = du( { dereference => 1 } , $dir );
exclude => PATTERN

Exclude files that match PATTERN.

Get the size of every file except for dot files:

$total = du( { exclude => qr/^\./ } , @files );
human-readable

Return sizes in human readable format (e.g., 1K 234M 2G)

$total = du ( { 'human-readable' => 1 } , @files );
Human-readable

Return sizes in human readable format, but use powers of 1000 instead of 1024.

$total = du ( { 'Human-readable' => 1 } , @files );
make-hash

Return the results in a hash.

%sizes = du( { 'make-hash' => 1 } , @files );
max-depth

Sets the max-depth for recursion. A negative number means there is no max-depth. Default is -1.

Get the size of every file in the directory and immediate subdirectories:

$total = du( { 'max-depth' => 1 } , <*> );
recursive

Sets whether directories are to be explored or not. Set to 0 if you don't want recursion. Default is 1. Overrides max-depth.

Get the size of every file in the directory, but not directories:

$total = du( { recursive => 0 } , <*> );
truncate-readable => NUMBER

Human readable formats decimal places are truncated by the value of this option. A negative number means the result won't be truncated at all. Default if 2.

Get the size of a file in human readable format with three decimal places:

$size = du( { 'human-readable' => 1 , 'truncate-readable' => 3 } , $file);
