This is allows much better copying performance on file system that have relatively high latency when retrieving individual files like S3QL. .sp \fBNote\fP: Using this program only improves performance when copying \fIfrom\fP an S3QL file system. When copying \fIto\fP an S3QL file system, using \fBpcp\fP is more likely to \fIdecrease\fP performance. .SH OPTIONS .sp The \fBpcp\fP command accepts the following options: .INDENT 0.0 .INDENT 3.5 .INDENT 0.0 .TP .BI \-\-log \ Destination for log messages. Specify \fBnone\fP for standard output or \fBsyslog\fP 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: \fBNone\fP .TP .B \-\-quiet be really quiet .TP .BI \-\-debug\-modules \ Activate debugging output from specified modules (use commas to separate multiple modules). Debug messages will be written to the target specified by the \fB\-\-log\fP option. .TP .B \-\-debug Activate debugging output from all S3QL modules. Debug messages will be written to the target specified by the \fB\-\-log\fP option. .TP .B \-\-version just print program version and exit .TP .B \-a Pass \-aHAX option to rsync. .TP .BI \-\-processes \ Number of rsync processes to use (default: 10). .UNINDENT .UNINDENT .UNINDENT .SH EXIT CODES .sp \fBpcp\fP may terminate with the following exit codes: .INDENT 0.0 .TP .B 0 Everything went well. .TP .B 1 An unexpected error occured. This may indicate a bug in the program. .TP .B 2 Invalid command line argument or configuration file key. .UNINDENT .SH SEE ALSO .sp \fBpcp\fP is shipped as part of S3QL, \fI\%https://github.com/s3ql/s3ql/\fP\&. .SH COPYRIGHT © 2008 Nikolaus Rath .\" Generated by docutils manpage writer. .
