28 pare. Each file name must be on a separate line.
29 -p prty
31 schedule the request the the specified priority, prty. The lowest
32 priority is 0.
33 Depending on the system configuration, priorities may or may not
34 be honored.
35 -s
37 requests that the file be copied into the cluster should it not be
38 found online (i.e. stage). Depending on the system configuration,
39 staging may or may not be honored.
40 -S
42 requests that the file be copied into the cluster should it not be
43 found on the same server as the first file in the specified list
44 of files When the file is copied it is co-located with the first
45 file in the list of files, if sufficient space exists on the tar‐
46 get server. Depending on the system configuration, co-location
47 may or may not be honored.
48 -w
50 when staging or co-locating the file, copy the file to a space
51 that allows file modification (i.e. the file will be modified).

57 target
58 is the redirector's hostname and optional port number where the
59 prepare is to occur. If the prepare is to occur on more than one
60 redirector, specified each one separated by a comma.
61 paths
63 are the files to be prepared. Specify one or more files separated
64 by a space. to occur. If the prepare is to occur on more than one
65 redirector, specified each one separated by a comma. If fB-f is
66 specified, you need not specify any files on the command line.
67 Files specified on the command line are always processed first.

71 Unless the -s or -S option is specified, file preparation merely seeds
72 the redirector's location cache. This allows the look-ups for prepared
73 files to progress much faster in the future.
