Linux 下按照文件大小查找文件

为什么需要这篇文章

我想大概是这种情况,你的Linux 机器下磁盘满了,需要清理,然后就需要查找大的文件,确定是否有用进行删除。

具体做法

查找500M以上的文件

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

查找整整500M的文件

1
sudo find / -size 500M

查找小于500M的文件

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

查找大于100M且小于500M的文件

1
2

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

其他查找单位

  • b – for 512-byte blocks (this is the default if no suffix is used)
  • c – for bytes
  • w – for two-byte words
  • k – for Kilobytes
  • M – for Megabytes
  • G – for Gigabytes
