Description
parrot_cp is a drop-in replacement for the Unix cp command. It provides better performance when copying
files to or from remote storage systems by taking advantage of whole-file transfer rather than copying
files block-by-block.
Examples
To use parrot_cp you can either call the code directly:
% parrot_run tcsh
% parrot_cp /tmp/mydata /chirp/server.nd.edu/joe/data
% exit
or alias calls to cp with calls to parrot_cp:
% parrot_run bash
% alias cp parrot_cp
% cp -r /chirp/server.nd.edu/joe /tmp/joe
% exit
Exit Status
On success, returns zero. On failure, returns non-zero.
