Das Skript wurde geschrieben, um mit find, cpio und pv die Aufgabe auszuführen. Die Rate kann begrenzt werden.

Es hier spiegeln:
#!/bin/bash set -e if [ $# -lt 2 ]; then echo "cppv - copy files with progress bar and rate limiting ability" echo "Usage: cppv source_file[s] destination_file_or_directory" echo "No other non-positional command line arguments can be given" echo "Always recurses like find" echo "You can change copying speed limit on the fly with \"pv -R\" if you find out pv's PID" echo "Use FIND_OPTS, PV_OPTS, CPIO_O_OPTS, CPIO_I_OPTS to override arguments to the pipeline parts" echo "Examples:" echo " cppv a b # Copy file a to b. Just calls \"pv a > b\"" echo " cppv a d/ # Copy file a to d/a.
