الاسم¶

scp — OpenSSH secure file copy

موجز¶

scp [-346ABCOpqRrsTv] [-c cipher] [-D sftp_server_path] [-F ssh_config] [-i identity_file] [-J destination] [-l limit] [-o ssh_option] [-P port] [-S program] [-X sftp_option] source ... target

الوصف¶

scp copies files between hosts on a network.

scp uses the SFTP protocol over an ssh(1) connection for data transfer, and uses the same authentication and provides the same security as a login session.

scp will ask for passwords or passphrases if they are needed for authentication.

The source and target may be specified as a local pathname, a remote host with optional path in the form [user@]host:[path], or a URI in the form scp://[user@]host[:port][/path]. Local file names can be made explicit using absolute or relative pathnames to avoid scp treating file names containing ‘:’ as host specifiers.

When copying between two remote hosts, if the URI format is used, a port cannot be specified on the target if the -R option is used.

الخيارات هي كما يلي:

-3

Copies between two remote hosts are transferred through the local host. This mode is the default, but see also the -R option for copying data directly between two remote hosts. Note that when using the legacy SCP protocol (via the -O flag), this option selects batch mode for the second host as scp cannot ask for passwords or passphrases for both hosts.

-4

يجبر scp على استخدام عناوين IPv4 فقط.

-6

يجبر scp على استخدام عناوين IPv6 فقط.

-A

يسمح بتمرير ssh-agent(1) إلى النظام البعيد. الافتراضي هو عدم تمرير وكيل المصادقة.

-B

Selects batch mode (prevents asking for passwords or passphrases).

-C

Compression enable. Passes the -C flag to ssh(1) to enable compression.

-c شفرة

Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1).

-D sftp_server_path

Connect directly to a local SFTP server program rather than a remote one via ssh(1). This option may be useful in debugging the client and server.

-F ssh_config

Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1).

-i identity_file

يختار الملف الذي تُقرأ منه الهوية (المفتاح الخاص) للاستيثاق بالمفتاح العام. يُمرر هذا الخيار مباشرة إلى ssh(1).

-J destination

اتصل بالمضيف المستهدف بإجراء اتصال scp أولاً بمضيف القفز الموصوف بـ destination ثم إنشاء توجيه TCP إلى الوجهة النهائية من هناك. يمكن تحديد قفزات متعددة مفصولة بفواصل. هذا اختصار لتحديد توجيه ضبط ProxyJump. يُمرر هذا الخيار مباشرة إلى ssh(1).

-l حد

يحد من عرض النطاق الترددي المستخدم، محددًا بالكيلوبت/ثانية.

-O

Use the legacy SCP protocol for file transfers instead of the SFTP protocol. Forcing the use of the SCP protocol may be necessary for servers that do not implement SFTP, for backwards-compatibility for particular filename wildcard patterns and for expanding paths with a ‘~’ prefix for older SFTP servers.

-o خيار_ssh

Can be used to pass options to ssh in the format used in ssh_config(5). This is useful for specifying options for which there is no separate scp command-line flag. For full details of the options listed below, and their possible values, see ssh_config(5).

-P port

Specifies the port to connect to on the remote host. Note that this option is written with a capital ‘P’, because -p is already reserved for preserving the times and mode bits of the file.

-p

Preserves modification times, access times, and file mode bits from the source file.

-q

الوضع الهادئ: يعطل مقياس التقدم ورسائل التحذير والتشخيص من ssh(1).

-R

Copies between two remote hosts are transferred through the local host by default. This option instead copies between two remote hosts by connecting to the origin host and executing scp there. This requires that scp running on the origin host can authenticate to the destination host without requiring a password.

-r

Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal.

-S برنامج

Name of program to use for the encrypted connection. The program must understand ssh(1) options.

-T

Disable strict filename checking. By default when copying files from a remote host to a local directory scp checks that the received filenames match those requested on the command-line to prevent the remote end from sending unexpected or unwanted files. Because of differences in how various operating systems and shells interpret filename wildcards, these checks may cause wanted files to be rejected. This option disables these checks at the expense of fully trusting that the server will not send unexpected filenames.

-v

Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configuration problems.

-X خيار_sftp

تحديد خيار يتحكم في جوانب سلوك بروتوكول SFTP. الخيارات الصالحة هي:

nrequests=value

يتحكم في عدد طلبات قراءة أو كتابة SFTP المتزامنة التي قد تكون جارية في أي وقت أثناء التنزيل أو الرفع. مبدئيًا يمكن أن يكون 64 طلبًا نشطًا بالتزامن.

buffer=value

يتحكم في الحجم الأقصى للخبيئة لعملية قراءة/كتابة SFTP واحدة أثناء التنزيل أو الرفع. تُستخدم خبيئة بحجم 32 كيلوبايت مبدئيًا.

حالة الخروج¶

The scp utility exits 0 on success, and >0 if an error occurs.

التاريخ¶

scp is based on the rcp program in BSD source code from the Regents of the University of California.

Since OpenSSH 9.0, scp has used the SFTP protocol for transfers by default.

تحذيرات¶

The legacy SCP protocol (selected by the -O flag) requires execution of the remote user's shell to perform glob(3) pattern matching. This requires careful quoting of any characters that have special meaning to the remote shell, such as quote characters.
