Server Command (hcpd)
The hcpd daemon is the software which receives the instruction commands sent from the remote clients such as, the hcp (file transfer) command and the hrm (file delete) command and waits to execute them at the server side, which is available on Linux.
Basic Format#
The basic format is as follows.
Usage: hcpd [OPTION]... or : hcpd -q [OPTION]...Option List#
The options for the hcpd commands are below.

Various Monitorings#
f, foreground#
=========================================================================Supported OS : Linux.x86Format : -f | --foreground=========================================================================Start the hcpd daemon in the foreground mode.
--Example:[root@localhost ~]# hcpd -f ...--investigation#
=========================================================================Supported OS : Linux.x86Format : --investigation=========================================================================The hcpd daemon starts in the investigation mode. In the case of unexpected behaviors and so on, detailed log is output for the investigation. This mode is not suitable for the long-time use and the case where the high performance is required on the transmission, because a lot of logs are output. Kindly send the log to the application developer for its investigation, because it is not for users but for the developers.
This option is deprecated. Instead, detailed log data can be obtained with SystemLogLevel or ApplicationLogLevel DEBUG.
Log Management#
l, log-file#
=========================================================================Supported OS : Linux.x86Format : -l <log-file-path> | --log-file=<log-file-path>-------------------------------------------------------------------------log-file-pathDefault : noneRange of Values : path string of file system=========================================================================This option specifies a path of a file to which the hcpd daemon output logs.
--Example:[root@localhost ~]# hcpd -l /var/log/hcpd.log ...--When this option is not specified, the log is output as the standard output.
L, stat-log-file#
=========================================================================Supported OS : Linux.x86Format : -L <log-file-path> | --stat-log-file=<log-file-path>-------------------------------------------------------------------------log-file-pathDefault : noneRange of Values : path string of file system=========================================================================This option specifies the path of the statistic log file which the hcpd daemon outputs.
--Example:[root@localhost ~]# hcpd -L /var/tmp/.hcp.statistics2 ...--Each statistics log is output in the specified path with suffix.
