In terms of file uploading, Linux has a command called SCP, which is a secure file upload, copy and download command that uses SSH to encrypt files when transferring them, ensuring file security during transmission. The general code for file uploading is: `scp [file] [username]@[hostname]:`[destination path].
As for downloading files, there are two commands in Linux that can be used, wget and curl. wget is a command that can synchronously download specified files, and curl is a command line tool used to transfer files. Both commands can be used to download files if a download link is passed. Generally, the code used looks like this: `wget https://example.com/file.zip`.
Sometimes, you need to move files between different computers. You can also use scp to achieve this. Using scp’s `-r` option to upload or download entire directories, the following command can be used: `scp -r [username]@[hostname]:[source path] [destination path]`. If a file already exists, you can use `-f` to forcibly overwrite it: `scp -f [username]@[hostname]:[source path] [destination path]`.
In short, Linux is an efficient and powerful operating system. There are many commands for file management, such as scp for file uploading and downloading, wget for downloading files, and curl for file transfer. With these commands, Linux file management can be more convenient.
