Finding Files
2.10 Filesystems
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 find avoid them.
There are two ways to avoid searching certain filesystems. One way is
to tell find to only search one filesystem:
- Option: -xdev
-
- Option: -mount
- 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:
- Test: -fstype type
- 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:
| | 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. See section 3.2 Print File Information. `-fstype' is
usually used with `-prune' to avoid searching remote filesystems
(see section 2.9 Directories).
