How to copy a file from a local machine to a remote Linux server
How to copy a file from a local machine to a remote Linux server
The most common method to copy a file from your local machine to a remote Linux server is using scp, which encrypts data and uses SSH authentication; for example, scp /path/to/local/file username@remote_host:/path/to/remote/directory copies a file securely, while adding the -P flag specifies a non-standard SSH port and -r enables recursive copying of directories.
To copy a file from your local machine to a remote Linux server, the most common and secure method is using scp (secure copy protocol). It encrypts the data during transfer and relies on SSH for authentication. Below are practical ways to do it.
Using scp Command
scp works from your local terminal and requires the target server’s address, username, and write permissions in the destination directory.
- Basic syntax:
scp /path/to/local/file username@remote_host:/path/to/remote/directory - Example:
scp document.txt user@192.168.1.100:/home/user/ - If SSH uses a non-standard port (not 22), use the -P flag:
scp -P 2222 file.txt user@host:/home/user/ - To copy recursively (for folders): add the
-rflag:scp -r /local/folder user@host:/remote/folder
Using rsync Over SSH
rsync is efficient for syncing files and folders, especially when resuming transfers or updating existing copies.
- Command format:
rsync -avz /local/file user@host:/remote/path - The
-aflag preserves permissions and symlinks,-venables verbose output, and-zcompresses data during transfer - Useful for large files or repeated syncs: only changed parts are transferred
Using SFTP (File Transfer via SSH)
SFTP provides an interactive way to transfer files, similar to FTP but secured over SSH.
- Start session:
sftp user@host - Once connected, use
put localfile.txt /remote/path/to upload - Use
lcdto change local directory andcdfor remote directory - Exit with
quit
For automation or scripts, consider setting up SSH key-based authentication to avoid entering passwords each time. Generate a key with ssh-keygen and copy the public key to the server using ssh-copy-id user@host.
Basically, scp is the quickest for one-off transfers, rsync is better for updates and large datasets, and SFTP suits interactive sessions.

How to setup file sharing using Samba on Linux? (SMB Protocol)
Mar 13, 2026 am 12:33 AM
The main reason why Windows cannot see the Samba share is that the firewall blocks UDP137–139/TCP445 or NetBIOS name resolution fails; it is necessary to confirm that the workgroup is consistent, the interfaces are configured correctly, the file permissions match forceuser/forcegroup, and set doscharset=UTF-8 to solve Chinese garbled characters.
How to extend a Logical Volume (LVM) in Linux without downtime?
Mar 13, 2026 am 12:53 AM
Logical volumes and file systems can be expanded online. You need to expand the LV first and then the file system. It is recommended to use lvextend-r for automatic synchronization adjustment, but you must ensure that the LVM and file system tool versions are compatible.
How to check open ports and listening services in Linux? (Netstat & SS)
Mar 10, 2026 am 01:08 AM
Netstat displays fewer LISTEN ports than ss because it does not display process information by default that non-root users do not have access to; ss can read all listening sockets by default without process names, and sudonetstat-tulpn is required to display them completely.
How to format disk partitions using the command line in Linux?
Mar 15, 2026 am 12:01 AM
When fdisk is stuck at the Command prompt, it is normally waiting for input. Enter q to exit safely; you must umount before mkfs, otherwise it may fail silently; partedmkpart does not support the specified file system type, and mkfs needs to be executed separately.
How to set up SSH key authentication on Linux? (Passwordless Login)
Mar 11, 2026 am 12:46 AM
It is recommended to use ssh-keygen-ted25519 to generate a key pair, because it is faster, more secure, and has a shorter key than the default RSA; it is necessary to strictly set the ~/.ssh directory permissions to 700 and authorized_keys to 600, and use ssh-v to confirm whether the client is Offering public key and whether the server rejects it.
How to configure a static IP address on Linux? (Netplan & NetworkManager)
Mar 14, 2026 am 12:02 AM
Netplan reports "InvalidYAML" when configuring a static IP due to indentation errors, missing spaces after colons, or mixed tabs; gateway4 has been deprecated and routes to:default must be used instead; NetworkManager needs to be modified before down/up takes effect; the renderer field is used to determine the backend during coexistence; incorrect DNS configuration will cause ping to succeed but curl to fail.

Mar 16, 2026 am 12:06 AM
The applicable scenarios of VNC and XRDP are different: VNC is suitable for complete graphics, multi-user, and cross-platform. Tigervnc-server is recommended and xstartup and port are correctly configured;
