In scp command we can specify the identify file or private key file using ‘-i’ option, example is shown below, $ scp -i my_key.pem -r Downloads :/root In most of the Linux environments, keys-based authentication is preferred. Example is shown below, $ scp -q -r Downloads :/var/tmpġ2) Use Identify File in scp while Copying
Use ‘-q’ option in scp command to suppress transfer progress, warning and diagnostic messages of ssh. Use ‘-p’ option in scp command to preserve permissions, access time and modes while copying from source to destination $ scp -p jdk-linux-圆4_bin.rpm :/var/tmp In above example, ssh port for remote host is “2022” 10) Preserves Permissions, Modes and Access Time While Copying There can be some scenario where ssh port is changed on destination host, so while using scp command we can specify the ssh port number using ‘-P’ option. Bandwidth is specified in Kbit/s, example is shown below, $ scp -l 500 jdk-linux-圆4_bin.rpm :/var 9) Use Different SSH Port in SCP Use ‘-l’ option in scp command to put limit on bandwidth usage while copying.
#Ssh copy file from local to remote download#
In the above example we are transferring the Download directory with compression enabled. We can increase the transfer or copy speed by enabling the compression using -C option, it will automatically enable compression at source and decompress at destination. $ 7) Increase Copy Speed by Enabling Compression 2 root root 75 Oct 19 12:10 /opt/Downloads Use below command to verify whether Download folder is copied to remote system or not, $ ssh "ls -ld /opt/Downloads"ĭrwxr-xr-x. Use -r option in scp command to recursively copy the entire directory from one system to another, example is shown below, $ scp -r Downloads :/opt 1 root root 747438080 Oct 19 12:02 /tmp/backup-Oct.zip 6) Copy Files and Directories Recursively $scp _hosts1:/ _host2:/Įxample is shown below, $ scp :~/backup-Oct.zip :/tmp Using scp command we can copy files and directories between two remote hosts, let’s suppose we have a local Linux system which can connect to two remote Linux systems, so from my local system I can use scp command to copy files across these two systems, ~]$ 5) Copy Files Across Two Remote Systems Specify the multiple files separated by space, example is shown below $ scp install.txt index.html jdk-linux-圆4_bin.rpm :/mnt Multiple files can be copied to remote system using scp command in one go. 's password: 4) Copy Multiple Files to Remote System
#Ssh copy file from local to remote password#
$ scp -v jdk-linux-圆4_bin.rpm :/optĮxecuting: program /usr/bin/ssh host 172.20.10.8, user root, command scp -v -t /optĭebug1: Reading configuration data /etc/ssh/ssh_configĭebug1: Reading configuration data /etc/ssh/ssh_config.d/nfĭebug1: Reading configuration data /etc/crypto-policies/back-ends/nfigĭebug1: /etc/ssh/ssh_config.d/nf line 8: Applying options for *ĭebug1: Connecting to 172.20.10.8 port 22.ĭebug1: Next authentication method: password This becomes very useful in debugging connection, authentication and configuration problems. Using verbose output we can easily find what exactly is happening in the background. We can enable verbose output with -v option while copying files via scp command. Suppose we want to copy a file from remote system to our local system under the /tmp folder, execute the following, $ scp :/root/Technical-Doc-RHS.odt /tmp Jdk-linux-圆4_bin.rpm 100% 10MB 27.1MB/s 00:00Ībove command will copy jdk rpm package file to remote system under /opt folder. Let’s assume we want to copy jdk rpm package from our local Linux system to remote system (172.20.10.8) using scp command, run $ scp jdk-linux-圆4_bin.rpm :/opt 1) Copy File From Local System to Remote System Lets deep dive into scp command examples. -r Copy files and directories recursively.-p Preserves permissions, modes and access time of files while copying.Some of the most widely used options in scp command are listed below,
