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 gcf
and pbg
manual pages 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).

changes and improvements to this software are reported and commented in
file $CADP/HISTORY.
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.
