.B find
To search the directory tree rooted at the given dir/file name for the files that match the given parameters: \fB--atime\fR (file was last accessed N*24 hours ago), \fB--ctime\fR (file's status was last changed N*24 hours ago), \fB--mtime\fR (file's data was last modified N*24 hours ago), \fB--obd\fR (file has an object on a specific OST or OSTs), \fB--size\fR (file has size in bytes, or \fBk\fRilo-, \fBM\fRega-, \fBG\fRiga-, \fBT\fRera-, \fBP\fReta-, or \fBE\fRxabytes if a suffix is given), \fB--type\fR (file has the type: \fBb\fRlock, \fBc\fRharacter, \fBd\fRirectory, \fBp\fRipe, \fBf\fRile, sym\fBl\fRink, \fBs\fRocket, or \fBD\fRoor (Solaris)), \fB--uid\fR (file has specific numeric user ID), \fB--user\fR (file owned by specific user, numeric user ID allowed), \fB--gid\fR (file has specific group ID), \fB--group\fR (file belongs to specific group, numeric group ID allowed). The option \fB--maxdepth\fR limits find to decend at most N levels of directory tree. The options \fB--print\fR and \fB--print0\fR print full file name, followed by a newline or NUL character correspondingly. Using \fB!\fR before an option negates its meaning (\fIfiles NOT matching the parameter\fR). Using \fB+\fR before a numeric value means \fIfiles with the parameter OR MORE\fR, while \fB-\fR before a numeric value means \fIfiles with the parameter OR LESS\fR.

-To list the striping info for a given filename or files in a directory, optionally recursively, for all files in a directory tree: \fB--quiet\fR (don't print object IDs), \fB--verbose\fR (print striping parameters), \fB--recursive\fR (recurse into subdirectories).

+To list the striping information for a given filename or directory. By default the stripe count, size, and offset will be returned. If you only want specific striping information then the options of \fB--count\fR,\fB--size\fR,\fB--index\fR or \fB--offset\fR plus various combinations of these options can be used to retrieve only what you want. What pools a file belong to can also be obtained with \fB--pool\fR. In the case where you only want details about the files object id information then the \fB--quiet\fR option is used. Additional information available about striping can be displayed with \fB--verbose\fR. The default behavior of lfs getstripe used to retrieve data about a directory is to list all the contents of that directory. If you wish to inquire only about that directory then \fB--directory\fR,can be used to list directory entries instead of its contents in the same manner as ls -d. This can be expanded with \fB--recursive\fR which will recurse into all subdirectories. You can filter the search to return only files that has a object on a specific OST with \fB--obd\fR.
