如何查看/ dev / sda5中的文件并删除它们

我是ubuntu16.04lts-win10双启动时的新ubuntu用户。 64gb ram，1 tb ssd，lenovo p50。 我给每个操作系统分配了500gb。

df -i / Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda5 28598272 1234421 27363851 5% / vivek@vivek:~$ sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL [sudo] password for vivek: NAME FSTYPE SIZE MOUNTPOINT LABEL sda 953.9G ├─sda4 ntfs 453.2G Windows ├─sda2 ntfs 450M Recovery ├─sda5 ext4 436.3G / ├─sda3 vfat 100M /boot/efi ├─sda1 128M └─sda6 swap 63.7G [SWAP] 

并且：

  vivek@vivek:~$ sudo fdisk -l Disk /dev/sda: 953.9 GiB, 1024209543168 bytes, 2000409264 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: blah blah blah blah blah Device Start End Sectors Size Type /dev/sda1 34 262177 262144 128M Microsoft reserved /dev/sda2 264192 1185791 921600 450M Windows recovery environment /dev/sda3 1185792 1390591 204800 100M EFI System /dev/sda4 1390592 951830527 950439936 453.2G Microsoft basic data /dev/sda5 951830528 1866817535 914987008 436.3G Linux filesystem /dev/sda6 1866817536 2000408575 133591040 63.7G Linux swap Update: looks like somehow sda5 is taking up all my space :( vivek@vivek:~$ df -Th Filesystem Type Size Used Avail Use% Mounted on udev devtmpfs 32G 0 32G 0% /dev tmpfs tmpfs 6.3G 9.4M 6.3G 1% /run /dev/sda5 ext4 430G 381G 27G 94% / tmpfs tmpfs 32G 56M 32G 1% /dev/shm tmpfs tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs tmpfs 32G 0 32G 0% /sys/fs/cgroup /dev/sda3 vfat 96M 29M 68M 30% /boot/efi tmpfs tmpfs 6.3G 88K 6.3G 1% /run/user/1000 

如何查看和删除/ dev / sda5的内容，因为我不知道它是如何96％满的？ 我的笔记本电脑一直抱怨device is out of space这太荒谬了

特伦斯命令后更新

更新2：让事情变得更加奇怪：
