你应该已经注意到,在 Linux 中使用 ls 命令 列出的目录内容中,目录的大小仅显示 4KB。这个大小正确吗?如果不正确,那它代表什么,又该如何获取 Linux 中的目录或文件夹大小?这是一个默认的大小,是用来存储磁盘上存储目录的元数据的大小。
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。
什么是 du 命令?
du 命令 表示 磁盘使用率。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

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

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

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
