mount 命令小记
Linux通过分区来管理文件，在安装系统的时候建议把/home/目录单独mount到一个分区，这样下次重装系统的时候会方便很多。
?
例如：
mount /etc/sda5? /home
mount /etc/sda6? /work
?
mount不会在开机自动运行，可以通过配置实现文件系统的自动挂载。
在/etc目录下有个fstab文件，它里面列出了linux开机时自动挂载的文件系统的列表
?
# /etc/fstab: static file system information.## Use 'blkid' to print the universally unique identifier for a# device; this may be used with UUID= as a more robust way to name devices# that works even if disks are added and removed. See fstab(5).## <file system> <mount point> <type> <options> <dump> <pass>proc /proc proc nodev,noexec,nosuid 0 0# / was on /dev/sda1 during installationUUID=195f527d-dcc0-4773-b461-18f1bdff0a58 / ext4 errors=remount-ro 0 1# swap was on /dev/sda3 during installationUUID=f36148f5-9239-402e-9696-36affd85fe17 none swap sw 0 0?
添加一行：
/dev/sda5?????? /duitang??????? ext4??? defaults??? 0?? 0
?
修改之后立即生效:
mount -a
?
卸载mount
umount /mnt/usb
