NAME

       pcp - Recursive, parallel copy of directory trees

SYNOPSIS

          pcp [options] <source> [<source> ...] <destination>

DESCRIPTION

       The pcp command is a is a wrapper that starts several sync processes to copy directory trees in parallel.
       This is allows much better copying performance on file system that  have  relatively  high  latency  when
       retrieving individual files like S3QL.

       Note: Using this program only improves performance when copying from an S3QL file system. When copying to
       an S3QL file system, using pcp is more likely to decrease performance.

OPTIONS

       The pcp command accepts the following options:

          --log <target>
                 Destination for log messages. Specify none for standard output or syslog for the system logging
                 daemon.  Anything  else will be interpreted as a file name. Log files will be rotated when they
                 reach 1 MiB, and at most 5 old log files will be kept. Default: None

          --quiet
                 be really quiet

          --debug-modules <modules>
                 Activate debugging output from specified modules (use commas  to  separate  multiple  modules).
                 Debug messages will be written to the target specified by the --log option.

          --debug
                 Activate  debugging  output from all S3QL modules. Debug messages will be written to the target
                 specified by the --log option.

          --version
                 just print program version and exit

          -a     Pass -aHAX option to rsync.

          --processes <no>
                 Number of rsync processes to use (default: 10).

EXIT CODES

       pcp may terminate with the following exit codes:

       0      Everything went well.

       1      An unexpected error occured. This may indicate a bug in the program.

       2      Invalid command line argument or configuration file key.
