Linux 下按照文件大小查找文件-CFANZ编程社区

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

1 2 3 4 5 6 7	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

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21	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

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 3 4	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
