![]() ![]() Many people believe that SCP is not a great way to transfer files because it’s slow, cumbersome, and not as secure as it could be. While SCP is still used frequently, especially when transferring small files quickly, it’s actually somewhat deprecated. If you don’t want to go through the progress meter and want everything to happen silently, you can use the quiet (-q) command. If it seems as though your files or directories aren’t being copied correctly, you can use the verbose (-v) function to find out more. ![]() This flag makes warnings and errors more verbose.īeing aware of these options can help you with troubleshooting. This flag removes the progress meter, as well as any warnings or errors. This flag will ensure that metadata is still accessible on the original file. This flag can be used to select a port on the host. This flag is the ssh_option flag it can pass options directly to the SSH module. This flag limits the amount of bandwidth that’s used during the transfer. This flag will ensure that the files are properly compressed. This will recursively copy entire directories, which means that it will also copy over subdirectories. But here’s what you need to think about with SCP: When you’re moving files locally, you really need to pay attention to -r (recursive) and -a (all). There are a few important options when using SCP with Linux. You will already be using a Secure Shell system with SCP, but the key-based system enables you to use it without having to enter in credentials each time. An SSH key-based system will let you copy multiple files or download a file locally without having to enter your password over and over again. ![]() You can get around this by having an SSH key-based authentication system with the remote server or remote host. When copying a file from a remote location or copying files and directories to a remote location, you’ll be prompted to enter a password for the remote system. Of course, if you’ve secured your devices properly (or the other administrator has), every single user has a password. You may have noticed that when you use SCP, you only put in a user name rather than a password. You can rename a file in Linux using the CP command, but if you’re using a remote host, you need to use SCP instead. You may get a progress bar if it’s taking a while. So, keep in mind the fact that you are going to need to know your username and your host when you try to copy files to and from a system.īecause you’re not so much copying as really downloading and uploading, you are likely to see that the file has been uploading for some time. Likewise, if you were copying a file from a network computer to your own computer, you’d do this: $scp If you were copying a file from your own computer, for instance, you’d do this: $scp While the SCP command does require host information, it only requires host information for the network locations. To get your user host information, you’ll need access to the host machine. What the above command will do is copy the to the using the user/host information that’s plotted out. You would use this command as follows: $scp The Linux SCP command is the same as the CP command except that it always requires host information, whereas the CP command only requires it when you’re transferring from network to network. | By Andrei Dumitrescu, Crystal Mind Academy Explore Course How do you use the Linux SCP command?
