5.2.10. /proc/filesystems
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.
