如何查看linux支持的filesystem类型

This file displays a list of the file system types currently supported by the kernel. Sample output from a generic 

/proc/filesystems

 file
looks similar to the following:

nodev   sysfs
nodev   rootfs
nodev   bdev
nodev   proc
nodev   sockfs
nodev   binfmt_misc
nodev   usbfs
nodev   usbdevfs
nodev   futexfs
nodev   tmpfs
nodev   pipefs
nodev   eventpollfs
nodev   devpts
ext2
nodev   ramfs
nodev   hugetlbfs
iso9660
nodev   mqueue
ext3
nodev   rpc_pipefs
nodev   autofs

The first column signifies whether the file system is mounted on a block device. Those beginning with

nodev

 are
not mounted on a device. The second column lists the names of the file systems supported.

The 

mount

 command cycles through the file systems listed here when one is not specified as an argument.
