scp Command Examples in LinuxUse the flexibility of an SSH connection to transfer files with scp command.

The scp (secure copy) command in Linux is a powerful tool for securely transferring files and directories between two locations over an SSH connection. It leverages the security of SSH to ensure that the data being transferred is encrypted and secure. This is particularly useful for website developers and server administrators who often need to transfer files to and from servers.

Here are some practical examples of how to use the scp command. These examples assume that you are familiar with the command line and have SSH access to the remote server.

Basic Syntax

The basic syntax of the scp command is:

scp [OPTION] [user@]SRC_HOST:]file1 [user@]DEST_HOST:]file2
  • OPTION: scp options such as cipher, ssh configuration, ssh port, limit, recursive copy, etc.
  • SRC_HOST, DEST_HOST: Source and destination hosts (can be an IP address or a hostname).
  • user: Username on the host. If omitted, it assumes the current user’s username.
  • file1, file2: Source and destination files.

1. Copying a File from Local to Remote

To copy a file from your local machine to a remote server:

scp /path/to/local/file.txt username@remotehost:/path/to/remote/directory/

This command will copy file.txt from the local machine to the specified directory on remotehost.

2. Copying a File from Remote to Local

To copy a file from a remote server to your local machine:

scp username@remotehost:/path/to/remote/file.txt /path/to/local/directory/

This command will copy file.txt from remotehost to the specified directory on your local machine.

3. Copying a Directory Recursively

To copy an entire directory from one location to another, use the -r option:

scp -r /path/to/local/directory username@remotehost:/path/to/remote/

This command recursively copies the directory and its contents to the remote host.

4. Specifying a Port

If SSH on the remote host listens on a non-standard port, use the -P option:

scp -P 2222 /path/to/local/file.txt username@remotehost:/path/to/remote/directory/

This command uses port 2222 for the SSH connection.

5. Using a Specific SSH Key

If you need to specify a particular SSH key, use the -i option:

scp -i /path/to/private/key /path/to/local/file.txt username@remotehost:/path/to/remote/directory/

6. Verbose Output

For debugging or more detailed output, use the -v option:

scp -v /path/to/local/file.txt username@remotehost:/path/to/remote/directory/

7. Limiting Bandwidth Usage

To limit the bandwidth used by scp, use the -l option:

scp -l 1024 /path/to/local/file.txt username@remotehost:/path/to/remote/directory/

This limits the bandwidth to 1024 Kbit/s.

8. Preserving File Attributes

To preserve file attributes such as timestamps and permissions, use the -p option:

scp -p /path/to/local/file.txt username@remotehost:/path/to/remote/directory/

Conclusion

The scp command is a versatile tool for securely transferring files between systems over an SSH connection. Its integration with SSH means it benefits from the same level of security and can be used in scripts and automated processes, making it an invaluable tool for website developers and server administrators. Remember to replace username, remotehost, and file paths with the actual user names, host names/IP addresses, and paths relevant to your use case.

Bill takes a look at how CP/M shaped personal computing as we know it today.

The Impact of CP/M on Personal Computing: A Comprehensive Overview

Introduction

In the annals of personal computing, few operating systems have had as profound an impact as CP/M (Control Program for Microcomputers). Developed by Gary Kildall in 1974, CP/M played a pivotal role in shaping the landscape of personal computing as we know it today. This article delves into the historical significance, technical innovations, and lasting legacy of CP/M in the realm of personal computing.

The Genesis of CP/M

CP/M emerged in an era when personal computing was in its nascent stages. Computers were predominantly large, expensive mainframes and minicomputers, inaccessible to the general public. Gary Kildall’s CP/M revolutionised this landscape by providing an operating system that could run on microcomputers, which were more affordable and accessible to hobbyists and small businesses.

Key Features and Technical Innovations

  1. File Management System: CP/M introduced a hierarchical file management system that became a blueprint for future operating systems. Its ability to handle files in a structured manner was revolutionary at the time.
  2. Separation of Hardware and Software: CP/M’s architecture separated the operating system from the hardware, using a layer called the BIOS (Basic Input/Output System). This abstraction allowed CP/M to run on a wide range of hardware platforms, setting a precedent for future operating systems.
  3. Command-Line Interface: CP/M featured a command-line interface (CLI), which was a standard method of interaction in early operating systems. This CLI was the precursor to DOS (Disk Operating System) and later Windows command line.
  4. Programming and Development: CP/M supported several programming languages, most notably BASIC and assembly language. This made it a popular platform for software development and contributed to the growth of the software industry.

CP/M’s Role in the Personal Computer Revolution

CP/M played a crucial role in the personal computer revolution of the late 1970s and early 1980s. It was the operating system of choice for many of the early microcomputers, including the Altair 8800 and Osborne 1. CP/M’s widespread adoption can be attributed to its portability across different hardware platforms, a feature that was rare at the time.

The Influence on Subsequent Operating Systems

The influence of CP/M is most notably seen in MS-DOS, Microsoft’s operating system which became the foundation for the PC revolution. MS-DOS borrowed heavily from CP/M’s command-line interface and file management system. The resemblance was so pronounced that it led to legal disputes between Microsoft and Digital Research, the company founded by Kildall to market CP/M.

CP/M’s Decline and Legacy

CP/M’s dominance began to wane with the rise of MS-DOS and the IBM PC in the early 1980s. However, its legacy endures in several ways:

  1. Foundation for Future Operating Systems: CP/M laid the groundwork for the development of future operating systems, particularly in terms of user interface and file management.
  2. Inspiration for Software Development: The operating system’s support for various programming languages fostered a generation of software developers and contributed to the burgeoning software industry.
  3. Cultural Impact: CP/M holds a place in computing history as one of the pioneering operating systems that democratised computing, moving it from the realm of corporations and academia to the general public.

Conclusion

In retrospect, CP/M’s contribution to personal computing is monumental. It not only introduced technical innovations that became staples in later operating systems but also played a crucial role in the personal computer revolution, paving the way for the ubiquity of personal computing today. While newer technologies have long since eclipsed CP/M, its influence is indelibly etched in the DNA of modern computing systems. As we continue to advance in the digital age, it’s important to acknowledge and appreciate these foundational technologies that have shaped our online world.
