在使用Linux时，我们可能需要获取特定目录的大小。 在GUI中，有文件管理器，如Dolphin，Gnome，Nautilus等。但是，如果我们需要在命令行中获取大小，该怎么办。

Linux 上有一些应用程序可以 获取目录的实际大小。其中，磁盘使用率（du）命令已被 Linux 管理员广泛使用。

我将向您展示如何使用各种选项获取文件夹大小。

du 命令 表示 磁盘使用率(Disk Usage)。这是一个标准的 Unix 程序，用于估计当前工作目录中的文件空间使用情况。

它使用递归方式总结磁盘使用情况，以获取目录及其子目录的大小。

如同我说的那样, 使用 ls 命令时，目录大小仅显示 4KB。参见下面的输出。

$ls-lh|grep^ddrwxr-xr-x3daygeekdaygeek4.0KAug213:57Bank_Detailsdrwxr-xr-x2daygeekdaygeek4.0KMar152019daygeekdrwxr-xr-x6daygeekdaygeek4.0KFeb162019drive-2daygeekdrwxr-xr-x13daygeekdaygeek4.0KJan62019drive-mageshmdrwxr-xr-x15daygeekdaygeek4.0KSep2921:32Thanu_Photos1) 在 Linux 上如何只获取父目录的大小

使用以下 du 命令格式获取给定目录的总大小。在该示例中，我们将得到 /home/daygeek/Documents 目录的总大小。

$du-hs/home/daygeek/Documents

或

$du-h--max-depth=0/home/daygeek/Documents/20G/home/daygeek/Documents

详细说明：

du – 这是一个命令

-h – 以易读的格式显示大小 (例如 1K 234M 2G)

-s – 仅显示每个参数的总数

–max-depth=N – 目录的打印深度

使用以下 du 命令格式获取每个目录（包括子目录）的总大小。

在该示例中，我们将获得每个 /home/daygeek/Documents 目录及其子目录的总大小。

$du-h/home/daygeek/Documents/|sort-rh|head-2020G/home/daygeek/Documents/9.6G/home/daygeek/Documents/drive-2daygeek6.3G/home/daygeek/Documents/Thanu_Photos5.3G/home/daygeek/Documents/Thanu_Photos/Camera5.3G/home/daygeek/Documents/drive-2daygeek/Thanu-videos3.2G/home/daygeek/Documents/drive-mageshm2.3G/home/daygeek/Documents/drive-2daygeek/Thanu-Photos2.2G/home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month916M/home/daygeek/Documents/drive-mageshm/Tanisha454M/home/daygeek/Documents/drive-mageshm/2g-backup415M/home/daygeek/Documents/Thanu_Photos/WhatsAppVideo300M/home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/Jan-2017288M/home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/Oct-2017226M/home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/Sep-2017219M/home/daygeek/Documents/Thanu_Photos/WhatsAppDocuments213M/home/daygeek/Documents/drive-mageshm/photos163M/home/daygeek/Documents/Thanu_Photos/WhatsAppVideo/Sent161M/home/daygeek/Documents/Thanu_Photos/WhatsAppImages154M/home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/June-2017150M/home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/Nov-20163) 在 Linux 上如何获取每个目录的摘要

使用如下 du 命令格式仅获取每个目录的摘要。

$du-hs/home/daygeek/Documents/*|sort-rh|head-109.6G/home/daygeek/Documents/drive-2daygeek6.3G/home/daygeek/Documents/Thanu_Photos3.2G/home/daygeek/Documents/drive-mageshm756K/home/daygeek/Documents/Bank_Details272K/home/daygeek/Documents/user-friendly-zorin-os-15-has-been-released-TouchInterface1.png172K/home/daygeek/Documents/user-friendly-zorin-os-15-has-been-released-NightLight.png164K/home/daygeek/Documents/ConfigServerSecurityandFirewall(csf)CheatSheet.pdf132K/home/daygeek/Documents/user-friendly-zorin-os-15-has-been-released-Todo.png112K/home/daygeek/Documents/user-friendly-zorin-os-15-has-been-released-ZorinAutoTheme.png96K/home/daygeek/Documents/distro-info.xlsx4) 在 Linux 上如何获取每个目录的不含子目录的大小

使用如下 du 命令格式来展示每个目录的总大小，不包括子目录。
