df comes from the coreutils software package and comes with it when the system is installed; we can use this command to check the disk usage and the location where the file system is mounted;
Example:
[root@localhost ~]# df -l 文件系统 容量 已用 可用 已用% 挂载点 /dev/sda3 4956316 3565088 1135396 76% / tmpfs 241320 12 241308 1% /dev/shm /dev/sda6 4806904 2523708 2039012 56% /media/disk /dev/sda1 4956284 3529796 1170656 76% /media/_ /dev/sda5 4845056 2581484 2019388 57% /media/disk-1
Note:
The partition format of the Linux system uses the xyzN format. xy represents the hard disk type. As shown in the above execution results, sd represents a SCSI hard disk and z represents The hard drive serial number, the first hard drive is a, the second hard drive is b, so to check how many hard drives there are on the Linux system, just pay attention to this.
