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¶
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
