A filesystem is a section of a disk, either on the local host or
mounted from a remote host over a network. Searching network
filesystems can be slow, so it is common to make
There are two ways to avoid searching certain filesystems. One way is
find to only search one filesystem:
Don't descend directories on other filesystems. These options are synonyms.
The other way is to check the type of filesystem each file is on, and not descend directories that are on undesirable filesystem types:
True if the file is on a filesystem of type type. The valid filesystem types vary among different versions of Unix; an incomplete list of filesystem types that are accepted on some version of Unix or another is:ext2 ext3 proc sysfs ufs 4.2 4.3 nfs tmp mfs S51K S52K
You can use ‘-printf’ with the ‘%F’ directive to see the types of your filesystems. The ‘%D’ directive shows the device number. See Print File Information. ‘-fstype’ is usually used with ‘-prune’ to avoid searching remote filesystems (see Directories).
