parrot_cp(1)

NAME

parrot_cp - a replacement for cp that provides higher performance when dealing with remote files via parrot_run.

SYNOPSIS

parrot_cp [options] ... sources ... <dest>

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.

OPTIONS

  • -f,--force
    Forcibly remove target before copying.
  • -i,--interactive
    Interactive mode: ask before overwriting.
  • -r
    Same as -R
  • -R,--recursive
    Recursively copy directories.
  • -s,--symlinks
    Make symbolic links instead of copying files.
  • -l,--hardlinks
    )Make hard links instead of copying files.
  • -u,--update-only
    Update mode: Copy only if source is newer than target.
  • -v,--version
    Verbose mode: Show names of files copied.
  • -h,--help
    Help: Show these options.

EXIT STATUS

On success, returns zero. On failure, returns non-zero.

EXAMPLES

% 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
