Introduction to using Linux from the Command Line

Standard Level - 2 days

If you require this training prior to attending another Embedded Linux course please contact the Bicard team to discuss your needs, or complete an online enquiry.

Linux is widely used as a development platform, and as the operating system for embedded systems. Whilst users of a desktop Linux installation may be able to run applications with limited knowledge of the operating system, a good working knowledge of the command line or shell will help you to make best use of Linux. It is also essential if you are working without a graphical desktop, for example in an embedded system.

Linux Fundamentals provides the engineer with a thorough introduction to using Linux from the command line. All the essential shell and basic operating system commands are taught, enabling you to start to utilise the power of the Linux operating system.

Linux Fundamentals is suitable for delegates with existing experience of the Windows operating system and for those who have used Linux or UNIX systems with a graphical desktop, or who have only a limited knowledge of the command line.

Workshops comprise approximately 50% of class time and are based around carefully designed exercises to reinforce and challenge the extent of learning.

  • The essential Linux and shell commands and shell syntax
  • Understand the Linux file system and directory structure
  • How to work with files
  • Exploit the power of command pipelines and filters
  • Take control of and managing the processes that are running
  • Create and use archives; mounting and unmounting disks
  • Basic network terminology and diagnosis of problems

  • Hardware and software engineers wanting to quickly get up to speed with Linux as a development platform
  • Embedded system developers where Linux is used in the embedded system
  • Support engineers who will be installing and managing applications hosted on Linux systems

  • A basic level of computer literacy is expected, for example from using a PC running Windows
  • No previous experience of Linux or UNIX is necessary
