Two forms of the er_cp command exist:
er_cp [-V] experiment1 experiment2 er_cp [-V] experiment-list directory
The first form of the er_cp command copies experiment1 to experiment2. If experiment2 exists, er_cp exits with an error message. The second form copies a blank-separated list of experiments to a directory. If the directory already contains an experiment with the same name as one of the experiments being copied the er_cp utility exits with an error message. The -V option prints the version of the er_cp utility. This command does not copy experiments created with earlier versions of the tools.
