2. 文件目錄磁盤用量統計命令du
- du = du-c ：展示當前目錄下所有文件夾的佔用容量,
➜ terraform-provider-example git:(master) du -c
8 ./.terraform/plugins/darwin_amd64
8 ./.terraform/plugins
8 ./.terraform
48 ./provider
16 ./scripts
➜ terraform-provider-example git:(master) du
8 ./.terraform/plugins/darwin_amd64
8 ./.terraform/plugins
8 ./.terraform
48 ./provider
16 ./scripts
- du -a : 展示目錄下所有文件的佔用容量，不推薦使用。
- du -k(g/m/h) : 與df類似，以KB(或GB, MB，可讀性較好的單位)來展示當前目錄下的目錄佔用容量, 一般建議用-h
➜ terraform-provider-example git:(master) du -h
4.0K ./.terraform/plugins/darwin_amd64
4.0K ./.terraform/plugins
4.0K ./.terraform
24K ./provider
8.0K ./scripts
- du -h [file]：查看某文件的大小, 文件名可改成匹配符
➜ terraform-provider-example git:(master) du -h go.sum
16K go.sum
➜ terraform-provider-example git:(master) du -h go*
4.0K go.mod
16K go.sum
- du -d [depth]：查看當前目錄下深度從0到[depth]的目錄佔用容量, du -d 0 等同於du -s, 即當前目錄佔用容量
➜ terraform-provider-example git:(master) du -h -d 1
4.0K ./.terraform
24K ./provider
8.0K ./scripts
