NAME

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

CONTENTS

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 );



DESCRIPTION

    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. Overrides symlink-size.

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 } , <*> );



sector-size => NUMBER All file sizes are rounded up to a multiple of this number. Any file that is not an exact multiple of this size will be treated as the next multiple of this number as they would in a sector-based file system. Common values will be 512 or 1024. Default is 1 (no sectors).



  $total = du( { sector-size => 1024 }, <*> );



show-warnings => 1 | 0 Shows warnings when trying to open a directory that isn’t readable.



  $total = du( { show-warnings => 0 }, <*> );



1 by default.

symlink-size => NUMBER Symlinks are assumed to be this size. Without this option, symlinks are ignored unless dereferenced. Setting this option to 0 will result in the files showing up in the hash, if make-hash is set, with a size of 0. Setting this option to any other number will treat the size of the symlink as this number. This option is ignored if the dereference option is set.



  $total = du( { symlink-size => 1024, sector-size => 1024 }, <*> );



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);
