ubuntu查看文件使用的大小

这是看哪个目录下面的大小

root@JSSH2ZABBIX0132003:~# df -lhFilesystem      Size  Used Avail Use% Mounted on/dev/vda1        20G  6.7G   12G  36% /none            4.0K     0  4.0K   0% /sys/fs/cgroupudev            2.0G  4.0K  2.0G   1% /devtmpfs           396M  424K  395M   1% /runnone            5.0M     0  5.0M   0% /run/locknone            2.0G     0  2.0G   0% /run/shmnone            100M     0  100M   0% /run/user/dev/vdc1       197G   58G  130G  31% /data

这个命令是看文件夹里面所有内容的大小

root@JSSH2ZABBIX0132003:~# du -h --max-depth=1 /var2.4G/var/log8.0K/var/mail4.0K/var/opt4.0K/var/local620M/var/www2.3G/var/lib1.7M/var/backups124M/var/cache872K/var/spool4.0K/var/tmp4.0K/var/crash4.0K/var/agentx5.4G/var
