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,
                 'all' for everything). 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 occurred. This may indicate a bug in the program.

       2      Invalid command line argument or configuration file key.
