DESCRIPTION
This utility can be used to create a new file with a specific striping pattern,
determine the default striping pattern, gather the extended attributes
- (object numbers and location) for a specific file.
+ (object numbers and location) for a specific file, and manipulate disk
+ quotas.
It can be invoked interactively without any arguments or in a non-interactive
mode with one of the arguements listed and explained below:
\layout List
\series bold
find
\series default
- To list the extended attributes for a given filename or files in a directory
- or recursively for all files in a directory tree.
- It can also be used to list the files that have objects on a specific OST.
+ To search the directory tree rooted at the given dir/file name for the
+ files that match the given parameters: --atime (file was last accessed
+ N*24 hours ago), --ctime (file's status was last changed N*24 hours ago),
+ --mtime (file's data was last modified N*24 hours ago), --obd (file has
+ an object on a specific OST).
+ The option --maxdepth allows find to decend at most N levels of directory
+ tree.
+ The options --print and --print0 print full file name, followed by a newline
+ and null character correspondingly.

+\series bold
+find
+\series default
+ To list the striping info for a given filename or files in a directory
+ or recursively for all files in a directory tree use one of the following
+ options: [--quiet|-q] [--verbose|-v] [--recursive|-r].
+ If one of these options is given find works in old (obsolete, please use
+ getstripe instead) mode.
