為什麼需要這篇文章
我想大概是這種情況，你的Linux 機器下磁盤滿了，需要清理，然後就需要查找大的檔案，确定是否有用進行删除。
具體做法
查找500M以上的檔案
sudo find / -size +500M
/swap.img
/home/androidyue/file_server/ubuntu_18.04.tar
/home/androidyue/bin/TeamCity-2019.2.2.tar.gz
/proc/kcore
find: ‘/proc/23619’: No such file or directory
複制
查找整整500M的檔案
sudo find / -size 500M
複制
查找小于500M的檔案
sudo find / -size -500M
/
/opt
/opt/containerd
/opt/containerd/lib
/opt/containerd/bin
/opt/gitlab
/opt/gitlab/sv
/opt/gitlab/sv/prometheus
/opt/gitlab/sv/prometheus/log
/opt/gitlab/sv/prometheus/log/run
/opt/gitlab/sv/prometheus/log/main
/opt/gitlab/sv/prometheus/log/supervise
/opt/gitlab/sv/prometheus/log/supervise/stat
/opt/gitlab/sv/prometheus/log/supervise/status
/opt/gitlab/sv/prometheus/log/supervise/pid
/opt/gitlab/sv/prometheus/log/supervise/lock
/opt/gitlab/sv/prometheus/log/supervise/ok
/opt/gitlab/sv/prometheus/log/supervise/control
/opt/gitlab/sv/prometheus/run
/opt/gitlab/sv/prometheus/env
複制
查找大于100M且小于500M的檔案
sudo find / -size -500M -size +100M
/sys/devices/pci0000:00/0000:00:02.0/resource2_wc
/sys/devices/pci0000:00/0000:00:02.0/resource2
/usr/bin/dockerd
