Practical Linux Course

Designed for researchers, including PhD students and postdocs, this course provides attendees with an introduction to the Linux operating system. Linux powers more than 90% of the world’s supercomputers, most internet servers, and more than a billion Android devices. Additionally, bioinformatics depends heavily on Linux since a lot of scientific software is written specifically for it.

This short and concise hands-on course will teach you how to effectively use Linux using the command line interface. You will be able to swiftly start using Linux both on a server, e.g., the LUMC Shark cluster, as well as on your personal computer. Learning outcomes:

  • Understand and navigate through the filesystem structure.
  • Obtain information about files and directories.
  • Manipulate, i.e., create, delete, move, and rename files and directories.
  • Inspect and edit files content.
  • Gather disk storage information.
  • Search for and within files.
  • Manage file and directory access permissions.
  • Connect to other computers.
