Once allocated directory size displayed by ls will not be reduced even if the contents will be deleted. It will still show the large size it formerly needed as Andre described.

Though a du does not show different output:
Code:
$> ll tmp
total 280
drwxr-xr-x 2 root root  278528 2010-02-19 09:34 .
drwxr-xr-x 3 root root   4096 2010-02-19 09:09 ..
$> ll| grep tmp
drwxr-xr-x 2 root root  278528 2010-02-19 09:34 tmp
$> ls -la tmp
total 280
drwxr-xr-x 2 root root  278528 2010-02-19 09:34 .
drwxr-xr-x 3 root root   4096 2010-02-19 09:09 ..
$> du -sk tmp
276     tmp

This is a Linux box using ext3. It could be that other OS'es and fs'es might behave different. To change that back you'll have to delete and recreate the directory.

JFS2 on AIX resizes the size dynamically after contents are deleted, just as a side note.

directory size with ls -l

am I right in assuming that in unix a directory size is just information about that directory stored somewhere on the file system, and not a sum of its contents? This is because ls -l gives 1024 as my directory size, when the directory contains many gigs worth of stuff. also, is du -sk dir ... (2 Replies)

Arch::TempFiles(3pm)					User Contributed Perl Documentation				      Arch::TempFiles(3pm)

NAME
Arch::TempFiles - help to manage temporary files/dirs SYNOPSIS
use Arch::TempFiles qw(temp_file_name temp_file temp_dir); # all will be removed automatically on the script completion my $file_name1 = temp_file(); my $file_name2 = temp_file_name("status"); my $dir_name = temp_dir("arch-tree"); use Arch::TempFiles; my $tmp = new Arch::TempFiles; $tmp->root($tmp->dir); my $file_name = $tmp->name; open OUT, ">$file_name"; close OUT; DESCRIPTION
This module deals with temporary file names. It is similar to File::Temp, but simplier and more focused. Also, File::Temp is relatively new and was not shipped with older perl versions. Both function interface and object oriented interface are supported. FUNCTIONS
/METHODS The following functions are available: temp_root, temp_name, temp_file_name, temp_dir_name, temp_file, temp_dir. The corresponding class methods are available too: root, name, file_name, dir_name, file, dir. temp_root [dir] $tmp->root [dir] Change or return the root of the temporary files and dirs. The default is either $ENV{TMP_DIR} or "/tmp". temp_name [label] $tmp->name [label] Return the unused temporary file name. The default file name is "/tmp/,,arch-XXXXXX" where XXXXXX is a random number. To change this name use "temp_root" and/or provide label that replaces "arch". Please note, that the operation of acquiring the file name using this function/method and actual creating of this file is not atomic. So you may need to call this method again if the creation is failed, for example if some other process created the same file in the middle. temp_file_name [label] $tmp->file_name [label] Like "temp_name", but stores the name in the file list that will be removed on the end (on object destruction). temp_dir_name [label] $tmp->dir_name [label] Like "temp_name", but stores the name in the dir list that will be removed on the end (on object destruction). temp_file [label] $tmp->file [label] Like "temp_file_name", but also creates the file. temp_dir [label] $tmp->dir [label] Like "temp_dir_name", but also creates the dir.
