怎样查看Linux目录文件实际大小？这篇文章运用了实例展示，详细介绍获取和查看文件大小命令的使用方法，可供感兴趣的小伙伴们参考借鉴，希望对大家有所帮助。
什么是 du 命令?
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 ^d
drwxr-xr-x 3 daygeek daygeek 4.0K Aug 2 13:57 Bank_Details
drwxr-xr-x 2 daygeek daygeek 4.0K Mar 15 2019 daygeek
drwxr-xr-x 6 daygeek daygeek 4.0K Feb 16 2019 drive-2daygeek
drwxr-xr-x 13 daygeek daygeek 4.0K Jan 6 2019 drive-mageshm
drwxr-xr-x 15 daygeek daygeek 4.0K Sep 29 21:32 Thanu_Photos
1) 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
2) 在 Linux 上如何获取每个目录的大小
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 -20
20G /home/daygeek/Documents/
9.6G /home/daygeek/Documents/drive-2daygeek
6.3G /home/daygeek/Documents/Thanu_Photos
5.3G /home/daygeek/Documents/Thanu_Photos/Camera
5.3G /home/daygeek/Documents/drive-2daygeek/Thanu-videos
3.2G /home/daygeek/Documents/drive-mageshm
2.3G /home/daygeek/Documents/drive-2daygeek/Thanu-Photos
2.2G /home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month
916M /home/daygeek/Documents/drive-mageshm/Tanisha
454M /home/daygeek/Documents/drive-mageshm/2g-backup
415M /home/daygeek/Documents/Thanu_Photos/WhatsApp Video
300M /home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/Jan-2017
288M /home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/Oct-2017
226M /home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/Sep-2017
219M /home/daygeek/Documents/Thanu_Photos/WhatsApp Documents
213M /home/daygeek/Documents/drive-mageshm/photos
163M /home/daygeek/Documents/Thanu_Photos/WhatsApp Video/Sent
161M /home/daygeek/Documents/Thanu_Photos/WhatsApp Images
154M /home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/June-2017
150M /home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/Nov-2016
3) 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 -10
9.6G /home/daygeek/Documents/drive-2daygeek
6.3G /home/daygeek/Documents/Thanu_Photos
3.2G /home/daygeek/Documents/drive-mageshm
756K /home/daygeek/Documents/Bank_Details
272K /home/daygeek/Documents/user-friendly-zorin-os-15-has-been-released-TouchInterface1.png
172K /home/daygeek/Documents/user-friendly-zorin-os-15-has-been-released-NightLight.png
164K /home/daygeek/Documents/ConfigServer Security and Firewall (csf) Cheat Sheet.pdf
132K /home/daygeek/Documents/user-friendly-zorin-os-15-has-been-released-Todo.png
112K /home/daygeek/Documents/user-friendly-zorin-os-15-has-been-released-ZorinAutoTheme.png
96K /home/daygeek/Documents/distro-info.xlsx
4) 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。$ du -hS /home/daygeek/Documents/ | sort -rh | head -20
5.3G /home/daygeek/Documents/Thanu_Photos/Camera
5.3G /home/daygeek/Documents/drive-2daygeek/Thanu-videos
2.3G /home/daygeek/Documents/drive-2daygeek/Thanu-Photos
1.5G /home/daygeek/Documents/drive-mageshm
831M /home/daygeek/Documents/drive-mageshm/Tanisha
454M /home/daygeek/Documents/drive-mageshm/2g-backup
300M /home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/Jan-2017
288M /home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/Oct-2017

92M /home/daygeek/Documents/Thanu_Photos/WhatsApp Images
90M /home/daygeek/Documents/drive-2daygeek/Thanu-photos-by-month/Dec-2017
5) 在 Linux 上如何仅获取一级子目录的大小
如果要获取 Linux 上给定目录的一级子目录(包括其子目录)的大小，请使用以下命令格式。$ du -h --max-depth=1 /home/daygeek/Documents/

6) 如何在 du 命令输出中获得总计
如果要在 du 命令输出中获得总计，请使用以下 du 命令格式。$ du -hsc /home/daygeek/Documents/* | sort -rh | head -10
20G total
