一、 df 命令
df 命令用来查看各个磁盘占用空间大小，默认以字节为单位，可以添加-h 选项以合适的单位显示。

[ma@ma ~]$ df Filesystem 1K-blocks Used Available Use% Mounted on /dev/vda1 41151808 5702332 33352428 15% / tmpfs 961040 0 961040 0% /dev/shm /dev/vdb1 20511244 12006916 7455760 62% /data /dev/vdc1 20511244 82052 19380624 1% /disk1 ossfs 274877906944 0 274877906944 0% /ossdata [ma@ma ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/vda1 40G 5.5G 32G 15% / tmpfs 939M 0 939M 0% /dev/shm /dev/vdb1 20G 12G 7.2G 62% /data /dev/vdc1 20G 81M 19G 1% /disk1 ossfs 256T 0 256T 0% /ossdata |
二、 du 命令
du 命令用来统计文件大小，-h 选项以合适单位显示，-s 选项显示总计可以统计文件夹大小：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
[ma@ma test]$ du -h 8.0K ./.git/info 4.0K ./.git/branches 4.0K ./.git/refs/tags 8.0K ./.git/refs/remotes/origin 12K ./.git/refs/remotes 8.0K ./.git/refs/heads 28K ./.git/refs 4.0K ./.git/objects/info 8.0K ./.git/objects/f0 4.0K ./.git/objects/pack 8.0K ./.git/objects/03 8.0K ./.git/objects/69 36K ./.git/objects 48K ./.git/hooks 8.0K ./.git/logs/refs/remotes/origin 12K ./.git/logs/refs/remotes 8.0K ./.git/logs/refs/heads 24K ./.git/logs/refs 32K ./.git/logs 180K ./.git 12K ./test 204K . [ma@ma test]$ du -hs # 统计所有文件的总计大小 204K . |
可以使用 du -hs * 分别统计各个文件和文件夹的大小：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
[ma@ma test]$ tree . ├── 2.md ├── README.md └── test ├── 2.md └── README.md 1 directory, 4 files [ma@ma test]$ du -sh * # 统计各个文件个文件夹大小 4.0K 2.md 4.0K README.md 12K test |
