查看磁盘的占用:
df -h
neil@dedia:~$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 139G 37G 96G 28% /
none 4.0K 0 4.0K 0% /sys/fs/cgroup
udev 983M 4.0K 983M 1% /dev
tmpfs 199M 500K 198M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 992M 0 992M 0% /run/shm
none 100M 0 100M 0% /run/user
/dev/sda1 180M 34M 134M 20% /boot
如果需要清理磁盘的话, 用 find 命令找出大文件,然后酌情删除:
find / -size +100M -exec ls -lh {} \;
这就是要查找磁盘上大于100m 的文件.
