Introduction to working with UNIX and bash (ONLINE LIVE TRAINING)

Beginners

PLEASE BE AWARE: This event is run online, if you wish to book for the in-person version, please click here.

The Unix shell (command line) is a powerful and essential tool for modern researchers, in particular those working in computational disciplines such as bioinformatics and large-scale data analysis. In this course we will explore the basic structure of the Unix operating system and how we can interact with it using a basic set of commands. You will learn how to navigate the filesystem, manipulate text-based data and combine multiple commands to quickly extract information from large data files. You will also learn how to write scripts, use programmatic techniques to automate task repetition, and communicate with remote servers (such as High Performance Computing servers).

Number of sessions: 1

UNIX, Linux, Bash, Data handling

During this course you will learn about:

• Navigating the filesystem using a terminal (text-based interface).
• Using bash as a tool for data manipulation and automation.
• Best practices for managing and maintaining scripts written in bash.
• How to work on remote servers.

After this course you should be able to:

• Recognise the uses of the command line for computational work.
• Become comfortable in using the command line, understanding how commands are structured and how to access their documentation.
• Navigate the filesystem from the command line and understand how to specify the location of files and directories.
• Perform basic file manipulations in Bash: combine multiple files together; count number of lines, words and characters in a file; extract text matching a pattern; counting unique values in a file.
• Combine multiple commands to solve more complex tasks.
• Write Bash scripts to record and make your analysis reproducible.
• Understand what a for loop is an how it can be used to automate repetitive tasks.
• Access remote servers and move data to/from them.
