/proc/filesystems: Find out what filesystems supported by kernel

/proc/filesystems is the file used to detect filesystems supported by running kernel. You can quickly run grep or cat command to display the list of all supported file system. nodev indicates that the file system is not associated with a physical device such as /dev/sdb1. If you see ext3 or vfat, it means you will be able to mount ext3 and vfat based file systems.
