Basic usage of scp command

The following command means Copy source_file_name to destination_folder under username account of destination_host.

在 Linux 中传输文件文件夹的 10个 scp 命令

> scp source_file_name username@destination_host:destination_folder

copy

There are many parameters that can be used in the scp command. The following are some parameters that may be used in daily operations.

Use the -v parameter to display detailed information of the scp process

The default scp command takes no parameters and will copy files silently in the background. Users only see the results when the process is complete or when an error occurs.

You can use the -v parameter to output debugging information to the screen. This can help you troubleshoot connectivity, authentication, and configuration issues.

Provide the modification time, access time and mode of the original file

The

-p parameter will help you solve this problem. An estimated time and connection speed will appear on the screen.

rumenz@local $ scp -p Label.pdf rumenz@192.168.1.110:.

Use the -C parameter to speed up file transfer

One of the parameters that can speed up file transfers is the -C range. This -C parameter will compress your files anytime and anywhere, the unique thing is that compression only happens on the network. When the file reaches the destination server, it is restored to its original size before compression.

If you are copying a large number of files over the network, the -C parameter will help you reduce the total time required.

压缩方法不适用于所有文件。当源文件已经被压缩时,就没有什么效果了。文件如.zip,.rar,pictures, 和.iso

更改 scp 密码以加密文件

默认情况下scp使用 AES-128 来加密文件。如果你想更改为其他密码对其进行加密,你可以使用 -c 范围。看看这个命令。

rumenz@local $ scp -c 3des Label.pdf rumenz@192.168.1.110:.

rumenz@202.x.x.x's password:
Label.pdf 100% 3672KB 282.5KB/s 00:13

上面的命令告诉scp使用3des algorithm来加密文件。请注意此参数使用 -c不是-C

使用 scp 命令限制带宽使用

另一个可能有用的参数是 -l 范围。这 -l 参数将限制使用的带宽制 。如果你执行自动化脚本来复制大量文件,这将很有用

rumenz@local $ scp -l 400 Label.pdf rumenz@192.168.1.110:.

rumenz@202.x.x.x's password:
Label.pdf 100% 3672KB 50.3KB/s 01:13

scp 默认带宽的单位是Kilobyte/sec(KB/s)。所以如果你想限制你的带宽scp最多只有50 KB/s,你需要将其设置为50 x 8=400.

指定要与 scp 一起使用的特定端口

scp正在使用端口22作为默认端口。但出于安全原因,你可以将端口更改为另一个端口. 例如,我们使用端口2249.

rumenz@local $ scp -P 2249 Label.pdf rumenz@192.168.1.110:.

rumenz@202.x.x.x's password:
Label.pdf 100% 3672KB 262.3KB/s 00:14

递归复制目录中的文件

有时我们需要复制目录和其中的所有文件,目录

rumenz@local $ scp -r documents rumenz@192.168.1.110:.

rumenz@202.x.x.x's password:
Label.pdf 100% 3672KB 282.5KB/s 00:13
scp.txt 100% 10KB 9.8KB/s 00:00

复> 制过程完成后,你将在目标服务器上找到一个名为documents及其所有文件。文件夹documents是自动创建的。

禁用进度表和警告 / 诊断消息

rumenz@local $ scp -q Label.pdf rumenz@192.168.1.110:.

rumenz@202.x.x.x's password:
rumenz@local $

可以看到,输入密码后,没有关于 scp 进程的信息。该过程完成后,你将再次看到提示。

通过代理使用 scp 复制文件

代理服务器通常用于办公环境。scp 本身没有配置代理。当你的环境使用代理时,你必须告诉scp 与代理进行通信。

例如代理地址是10.0.96.6代理端口是8080.代理还实现了用户身份验证。首先,你需要创建 ~/.ssh/config文件

ProxyCommand /usr/bin/corkscrew 10.0.96.6 8080 %h %p ~/.ssh/proxyauth

然后你需要创建文件 ~/.ssh/proxyauth 里面输入。

myusername:mypassword

前提是需要安装corkscrew

$ apt-get install corkscrew

Centos系统可以用yum安装corkscrew

# yum install corkscrew

由于 ~/.ssh/proxyauth 文件包含你的 usernamepassword 以明文格式,请确保该文件只能自己访问。

选择不同的ssh_config 文件

对于经常在公司网络和公共网络之间切换的移动用户来说,总是在scp中更改设置会很痛苦。

场景示例

代理在公司网络中使用,但不在公共网络中使用,并且你定期切换网络。

rumenz@local $ scp -F /home/pungki/proxy_ssh_config Label.pdf

rumenz@192.168.1.110:.
rumenz@202.x.x.x's password:
Label.pdf 100% 3672KB 282.5KB/s 00:13

默认情况下 ssh_config 每个用户的文件将被放置在 ~/.ssh/config。创建一个特定的 ssh_config 具有代理兼容性的文件将更容易在网络之间切换。

当你在公司网络,你可以使用 -F 范围。当你在公共网络上时,你可以不用-F参数。

How to process in Linux Linux FIFO scheduling policy How to process in Linux Linux FIFO scheduling policy Sep 03, 2025 pm 12:39 PM

To make Linux processes run in real-time FIFO scheduling, you need to use the chrt command or sched_setscheduler system call to set the scheduling policy and priority, such as sudochrt-f99./app or configure SCHED_FIFO and priority parameters in the C program, and ensure that the process has CAP_SYS_NICE capability or root permissions, and configure rtprio and memlock restrictions through limits.conf to ensure real-timeness and avoid priority reversal. You need to use a mutex that supports priority inheritance.

Huawei HarmonyOS 6 system cancels the 'NEXT' suffix: It will be native Hongmeng in the future Huawei HarmonyOS 6 system cancels the 'NEXT' suffix: It will be native Hongmeng in the future Sep 24, 2025 pm 04:12 PM

The latest news on September 18th, Huawei HarmonyOS6 has launched multiple rounds of preview version push for developers, and has recently opened the experience qualification to some users who have tried it out for the first time. According to user feedback, the current system name no longer displays the "NEXT" suffix, and it is officially renamed to HarmonyOS6.0. Huawei initially proposed the name HarmonyOSNEXT for the first time at the developer conference in August 2023, aiming to mark the Hongmeng system entering a new stage of development and realizing true native self-development. HarmonyOSNEXT's most core breakthrough is to completely adopt the underlying system architecture developed independently, completely remove the Linux kernel and Android AOSP code, and only run applications based on the HarmonyOS kernel.
