parrot_locate - provides the true location of the data stored in a named file.
parrot_locate utilises parrot system calls to identify where the data stored as the file
at <path> is actually located. For example, running parrot_locate on a file stored in a
chirp multi-volume will return the server name and file path on the server where the data is.
Running it on a file stored in hdfs will return the list of chunk servers storing the file.
Note that parrot_locate varies depending on the underlying system. Most systems return output
in the form "<server>:<real path>", but that output is not guaranteed.
parrot_locate has no options.
Environment variables required by parrot_locate are system dependent.
Most systems do not use or require any. Refer to the specific system's documentation
for more information.
On success, returns zero. On failure, returns non-zero.
To check the location of a file stored in chirp:
% parrot_run parrot_locate /chirp/server.nd.edu/joe/data
or a file stored in a chirp multi-volume
% parrot_run parrot_locate /multi/server.nd.edu@multivol/data
