pbg_cp - copy a partitioned BCG graph
pbg_cp [
-i ]
source[.pbg] target[.pbg]
pbg_cp copies
source.pbg, which is a partitioned BCG graph
encoded in the PBG format, into
target.pbg. Both names
source.pbg and
target.pbg
must not designate the same file. If
target.pbg already exists, it is removed
first, as well as all the BCG fragments and log fragments referred to
in
target.pbg (these fragments being stored either on the local machine
or on remote machines); however, the grid configuration file referred
to in
target.pbg is not removed, as this file may be used by other PBG files
than
target.pbg.
The difference between pbg_cp and the UNIX command cp is
that pbg_cp does a "deep" copy, whereas cp does a "shallow" copy (only
source.pbg is copied and only target.pbg is removed if it exists already,
but their associated fragments are kept unchanged).
Refer to the distributor
manual page for details about the GCF and PBG formats.
- -i
- Prompt for
overwrite confirmation whenever target.pbg already exists. Any answer starting
with 'y' or 'Y' means that the copy should proceed. Any other answer prevents
overwriting to take place.
Exit status is 0 if everything is
alright, 1 otherwise.
An early prototype was written by Jerome Fereyre
and Hubert Garavel. The current version was developed by Wendelin Serwe
and Hubert Garavel (INRIA Rhone-Alpes).

pbg_cp was not designed
to ensure atomic transactions. If an error occurs while copying certain
fragments,
pbg_cp will abort the copy and try to remove all fragments already
copied. However, if
target.pbg already existed, its removal and the removal
of its fragments cannot be undone.
