Client Command (hcp)

The hcp command works to transfer files between the remote server and the hcpd daemon and also to copy files in the local network.

Basic Format#

The basic format is as follows.

Local  : hcp [OPTION]... SOURCE [SOURCE]... DEST  or   : hcp [OPTION]... -f SOURCE_LIST_FILE DEST
Remote :   Push : hcp [OPTION]... SOURCE [SOURCE]... [USER@]HOST[:PORT]:DEST  Pull : hcp [OPTION]... [USER@]HOST[:PORT]:SOURCE [:SOURCE]... DEST
Remote using source file list :   Push : hcp [OPTION]... -f SOURCE_LIST_FILE [USER@]HOST[:PORT]:DEST  Pull : hcp [OPTION]... -f SOURCE_LIST_FILE DEST  Pull : hcp [OPTION]... --source-file-host=HOST [--port=PORT] [--user=USER] -f SOURCE_LIST_FILE DEST

Copy#

p, permission#

=========================================================================Supported OS : Linux / WindowsFormat : -p | --permission=========================================================================

The file permission from the source (UID/GID, the flag with the execution right and so on) and file attributes (modification date and so on) are stored in the destination. When the permission and file attributes can’t be stored in the destination due to the access right, the attributes applied by OS when written in the file are kept.

--Example:[user@localhost ~]$ hcp -p ...--

R, recursive#

=========================================================================Supported OS : Linux / WindowsFormat : -R | --recursive=========================================================================

The directory from source is searched recursively and the file is transfered.

--Example:[user@localhost ~]$ hcp -R ...--

g, regex#

=========================================================================Supported OS : Linux / WindowsFormat : -g | --regex=========================================================================

The path from source is regarded as a regular expression.The path from source is regarded as a pattern string including wildcard (*) when no use of the option.

When specified path from source is not found as a directory or a file,verification by regular expression is carried out.In searching files, the names of files and directories are verified in this way.Files and directories which doesn’t match the pattern is skipped.Pattern strings is chosen from the strings after the last path delimiter (“/”).

--Example:[user@localhost ~]$ hcp -g ...--

Y, anydirs#

=========================================================================Supported OS : Linux / WindowsFormat : -Y | --anydirs=========================================================================

In the case that pattern matching is set by regex option or wildcard, directory search is carried out ignoring the pattern matching.

--Example:[user@localhost ~]$ hcp -Y ...--

y, verify#

=========================================================================Supported OS : Linux / WindowsFormat : -y | --verify=========================================================================

Data blocks and files to send are verified by message digest.

--Example:[user@localhost ~]$ hcp -y ...--

z, compress#

=========================================================================Supported OS : Linux / WindowsFormat : -z | --compress=========================================================================

Data blocks to send are compressed.

--Example:[user@localhost ~]$ hcp -z ...--

s, copy-linkfile#

=========================================================================Supported OS : Linux / WindowsFormat : -s | --copy-linkfile=========================================================================

hcp copies files that a symbolic link refers. A symbolic link is created in the destination, when this option is not used.

--Example:[user@localhost ~]$ hcp -s ...--

S, follow-linkdir#

=========================================================================Supported OS : Linux / WindowsFormat : -S | --follow-linkdir=========================================================================

hcp searches the directories that a symbolic link refers.

It should be noted that much data processing may happen with using this option, which is not unexpected with the information (number of files and their total size) got from the source path without resolving cyclic directory searches or its link.

--Example:[user@localhost ~]$ hcp -S ...--

H, dereference-src#

=========================================================================Supported OS : Linux / WindowsFormat : -H | --dereference-src=========================================================================

hcp makes dereference of symbolic links specified on SOURCE to copy files and directories.

--Example:[user@localhost ~]$ hcp --dereference-src ...--

e, no-emptyfile#

=========================================================================Supported OS : Linux / WindowsFormat : -e | --no-emptyfile=========================================================================

hcp dose not copy empty files.

--Example:[user@localhost ~]$ hcp -e ...--

E, no-emptydir#

=========================================================================Supported OS : Linux / WindowsFormat : -E | --no-emptydir=========================================================================

hcp dose not copy empty directories that have no files and no directories.

--Example:[user@localhost ~]$ hcp -E ...--

d, no-dotfile#

=========================================================================Supported OS : Linux / WindowsFormat : -D | --no-dotfile=========================================================================

hcp dose not copy files whose name starts with “.”.

--Example:[user@localhost ~]$ hcp -d ...--

hcp copies hidden files.

--Example:[user@localhost ~]$ hcp -I ...--

A, archive-check#

=========================================================================Supported OS : WindowsFormat : -A | --archive-check=========================================================================

hcp copies files having archive attributes.

When the destination OS is Windows including the case when this option isn’t set, the archive attribute is set at the right time following the OS behavior.(This software doesn’t set any archive attribute configurations even when creating a new file and updating.)

--Example:[user@localhost ~]$ hcp -A ...--

m, copy-mode#

=========================================================================Supported OS : Linux / WindowsFormat : -m <mode_name> | --copy-mode=<mode_name>-------------------------------------------------------------------------mode_nameDefault : ALLCOPYRange of Values : ALLCOPY, UPDATE, DIFF, DIFF_STRICT, SYNC=========================================================================

The file copy mode is set.

ALLCOPY means copying all files.

In the UPDATE mode, the source file and the destination file are compared and when the source file is newer than the destination one, hcp copies the source file.

In the DIFF mode, the file size is also compared in addition to UPDATE.

In the DIFF_STRICT mode, the hashes of files are also compared in addition to DIFF.

In the SYNC mode, the destination file which doesn’t exists in the source,is deleted.(synchronization)

--Example:[user@localhost ~]$ hcp -m UPDATE ...--

o, overwrite#

=========================================================================Supported OS : Linux / WindowsFormat : -o <overwrite_name> | --overwrite=<overwrite_name>-------------------------------------------------------------------------overwrite_nameDefault : FORCERange of Values : CONFIRM, FORCE, RENAME, BACKUP=========================================================================

As for overwriting,the mode is set.

The CONFIRM mode overwrites with confirmation.

The FORCE mode overwrites without confirmation.

The RENAME mode renames the file by adding a following suffix on the original file names before overwriting.

.YYMMDD_HHMMSS.NNN (NNN are the sequence numbers)

The BACKUP mode moves the original file to the following backup directory before overwriting.

./YYMMDD_HHMMSS/

The directory name is created in the unique process during transactions.

--Example:[user@localhost ~]$ hcp -o CONFIRM ...--

a, fail-action#

=========================================================================Supported OS : Linux / WindowsFormat : -a <action_name> | --fail-action=<action_name>-------------------------------------------------------------------------action_nameDefault : HALTRange of Values : HALT, SKIP=========================================================================

The behavior in the case of file copy errors is set.

no-out-of-order-header-messaging#

=========================================================================Supported OS : Linux / WindowsFormat : --no-out-of-order-header-messaging=========================================================================

It suppresses out-of-order of the control message (including file request messages). It unlocks the behaviors such as sending only control messages by the primary connection in the multiple connection mode and the content data (messages including file payload) in the secondary connection. It enables to send all messages in all connections.

preserve-win-read-only#

=========================================================================Supported OS : Linux / WindowsFormat : --preserve-win-read-only=========================================================================

overwrite-als-temp-file#

=========================================================================Supported OS : Linux / WindowsFormat : --overwrite-als-temp-file=========================================================================

It requests to overwrite a temporary file which already exists.

Without this option, the transferring file goes to the transfer error when a temporary file already exists.

As long as AtomicLikeSavingRejectOverwriteRequest is set to yes in the server setting, even though this option is on, overwriting a temporary file which already exists is rejected.

Authentication#

wss-no-check-certificate#

=========================================================================Supported OS : Linux / WindowsFormat : --wss-no-check-certificate=========================================================================

It instructs not to check server certificates when SSL/TLS in the WebSocket protocol is used. As a result, it receives server certificates without checking the CN (Common Name), expiration, intermediate certificate, and root certificate.

user#

=========================================================================Supported OS : Linux / WindowsFormat : --user=<username>-------------------------------------------------------------------------usernameDefault : noneRange of Values : user name=========================================================================

=========================================================================Supported OS : Linux / WindowsFormat : -r <run-record-path> | --resume=<run-record-path>-------------------------------------------------------------------------run-record-pathDefault : noneRange of Values : path string of file system=========================================================================

hcp restarts file operations with the execution records (the forwarding execution records output in .hcp.out).

--Example:[user@localhost ~]$ hcp ...[user@localhost ~]$ mv .hcp.out .hcp.in[user@localhost ~]$ hcp -r .hcp.in ...--

auto-resume#

=========================================================================Supported OS : Linux / WindowsFormat : --auto-resume=========================================================================

It automatically restarts copying when transmission stops due to network errors. However, in the case that a user stops copying by Ctrl+C, it doesn’t restart copying at that time.

It is recommended to use private keys that are not encrypted by passpharses for this purpose. If you need the passphrases, hcp make a cache on the memory of that passphrase to prevent interactive prompts from being shown for re-authentication.

Performance Evaluation#

N, no-send#

=========================================================================Supported OS : Linux / WindowsFormat : -N | --no-send=========================================================================

hcp runs without transferring data to the network.

This option is used to confirm the disk I/O at source and the performance of data processing.

--Example:[user@localhost ~]$ hcp -N ...--

n, no-diskio#

=========================================================================Supported OS : Linux / WindowsFormat : -n <bench_spec> | --no-diskio=<bench_spec> bench_spec := <number_of_files>:<file_size>-------------------------------------------------------------------------number_of_filesDefault : noneRange of Values : unsigned integer-------------------------------------------------------------------------file_sizeDefault : noneRange of Values : unsigned double-length integer=========================================================================

hcp runs without performing local I/O at source and destination.

This option is used to check the network transmission performance. Each meanings of the option parameter are below.

number_of_files := the number of files to transferfile_size := the size to transfer files (byte)

When the option is “0:0”, the sender path is searched as the normal operation and the file is transfered.(References of file attributes for the permission option and reading data of files are not carried out.)

This option is available even when /dev/zero is specified at the destination. In this case, it practically reads, transfers and writes the data from /dev/zero to the destination, whose size is specified by file_size in this option. Unlike the behavior described above, the I/O processing is not omitted. This option is typically used to check the transmission performance by specifying /dev/null at the destination and adding read/write by special devices.

--Example1:[user@localhost ~]$ hcp -n 1000:1048576 ...Example2:[user@localhost ~]$ hcp -n 1:1048576 /dev/zero 192.168.10.100:874:/dev/null--

FS (File Sync) shows file synchronization processing. When the synchronization deletes files in the destination that don’t exist on the source host, the following text is recorded.

--Example:\SRC /home/user/Desktop/hcp_src5\DST 127.0.0.1:11112:/home/user/Desktop/hcp_dst5\OK 0000 FS 80000001 /home/user/Desktop/hcp_src5/file1.txt\OK 0000 FS 80000002 /home/user/Desktop/hcp_src5/file2.txt\OK A001 FS 80000003 /home/user/Desktop/hcp_src5/file3.txt\OK 0000 FT 00000001 /home/user/Desktop/hcp_src5/file1.txt\OK 0000 FT 00000002 /home/user/Desktop/hcp_src5/file2.txt\EXIT 0 REASON 0000\--

When a file cannot be identified in a single source, the index of the source label is shown by “?.”

--Example:\SRC0 /home/user/Desktop/hcp_src5\SRC1 /home/user/Desktop/hcp_src6\DST 127.0.0.1:11112:/home/user/Desktop/hcp_dst5\OK 0000 FS 80000001 SRC0 /home/user/Desktop/hcp_src5/file1.txt\OK 0000 FS 80000002 SRC0 /home/user/Desktop/hcp_src5/file2.txt\OK 0000 FS 80000003 SRC1 /home/user/Desktop/hcp_src6/file3.txt\OK 0000 FS 80000004 SRC1 /home/user/Desktop/hcp_src6/file4.txt\OK A001 FS 80000005 SRC? /home/user/Desktop/hcp_src6/file5.txt\OK 0000 FT 00000001 SRC0 /home/user/Desktop/hcp_src5/file1.txt\OK 0000 FT 00000002 SRC0 /home/user/Desktop/hcp_src5/file2.txt\OK 0000 FT 00000003 SRC1 /home/user/Desktop/hcp_src6/file3.txt\OK 0000 FT 00000004 SRC1 /home/user/Desktop/hcp_src6/file4.txt\EXIT 0 REASON 0000\--

multi-run#

=========================================================================Supported OS : Linux / WindowsFormat : --multi-run=<record-path>[:<output-switch>]-------------------------------------------------------------------------record-pathDefault : noneRange of Values : path string of file system-------------------------------------------------------------------------output-switchFormat : ( (A|T|R|L)[...] | THRU | FULL )Default : THRU=========================================================================

A client starts in the multiple run mode. With this option, the following logs are recorded in unique file names in the specified directory. It is used when plural clients access to the same directory simultaneously or executing another applications is taken place in the background.

Application statistics
Transport statistics
Result output
Application log

record-path specifies the directory of these log files.

output-switch specifies the control of these logs outputs.

A stands for the application statistics. With this option, the application statistics is recorded in the following file name in the directory specified above.

hcp.mr.<YYYYMMDD_hhmmss_msec>.<pid>.statistics.application

T stands for the transport statistics. With “T”,the transport statistics is recorded in the following file name in the above directory.

hcp.mr.<YYYYMMDD_hhmmss_msec>.<pid>.statistics.transport.<protocol>

R stands for the execution result. With “R”,the execution result is recorded in the following file name in the above specified directory.

hcp.mr.<YYYYMMDD_hhmmss_msec>.<pid>.out

L stands for the application log. With “L”,the application log is recorded in the following file name in the above specified directory.

hcp.mr.<YYYYMMDD_hhmmss_msec>.<pid>.log

With “FULL”, the behavior is the same as one with “ATRL”.

With “THRU”, outputs of the records are processed following the specifications of the configuration files and commands. When the application statistics (transport statistics) in the configuration file is enable,it is recorded in the above file name. When the result output (the application log) is enable (without -v and with -l),the execution record (log) is output in the above file name.

--Example:[user@localhost ~]$ hcp --multi-run=/var/tmp:ATR // The log is output as standard. Other files are output in /var/tmp.--

System Operating Environment Settings#

config-file#

=========================================================================Supported OS : Linux / WindowsFormat : --config-file=<config-file-path>-------------------------------------------------------------------------config-file-pathDefault : noneRange of Values : path string of file system=========================================================================

The configuration file path used for the hcp command is set.

The hcp commands read the configuration files in the following order.

/etc/hcp/hcp.conf
\<user home directory>/.hcp/hcp.conf
\<the path configured in the options>

When the file doesn’t exist, it is skipped. When the configuration file wasn’t read successfully, file read error occurs and the operation stops.

--Example:[user@localhost ~]$ hcp --config-file=hcp.conf ...--

config-option#

=========================================================================Supported OS : Linux / WindowsFormat : --config-option=<config-file-option-desc>-------------------------------------------------------------------------config-file-option-descDefault : noneRange of Values : description of a configuration item described in configuration files=========================================================================

This option tells the hcp command to apply a configuration item from the command line parameters instead of using configuration files.

The configuration item will be applied at last after other configuration files are loaded.

--Example:[user@localhost ~]$ hcp --config-option="ApplicationLog DEBUG" ...--

include-conf-from-cwd#

=========================================================================Supported OS : Linux / WindowsFormat : --include-conf-from-cwd=========================================================================

When using Include in a relative path on configuration files, this option enables finding a file with a path relative to the current directory where commands run.

no-earlier-serv-compat#

=========================================================================Supported OS : Linux / WindowsFormat : --no-earlier-serv-compat=========================================================================

This option disables the backward compatibility for servers that will be performed when the connecting servers are earlier than the client. This function is available to work if you do not use some functions. This option disables the function works (earlier version’s clients are still available to work with newer version’s servers in that condition). Please see the Server backward compatibility conditions list in the back of this document about what conditions the function works in.
