You can do this by running the following: To follow along, you will need to install GNU sed on your Mac using brew. This tutorial was created using GNU sed v4.7 on Ubuntu 20.04. You can learn more about the differences between the two versions in this breakdown. This version of sed has some variations from GNU sed on Linux distros. In this article, you’ll learn more about how this powerful tool can help you, from simple find and replace commands to more complex use cases. sed commands and conditions can be supplied in a script file or through arguments to the CLI command, then run automatically.įinally, it is appropriate for use cases in which text is provided as an input stream from other CLI tools, which may need to read the output stream that sed returns. It’s also great for automation-like build processes. With sed, you can target a portion of input text using line addresses and regular expressions. It’s a powerful tool for text processing tasks, like filtering, search, and substitutions, and works well in situations where high precision is needed. And it’s efficient since you only have to run it once to process a file compared to other GUI-based text processing tools. It’s flexible enough to work with other CLI tools using pipelines. Sed is also easily accessible from the command line, so it’s helpful for regular tasks, like searching and filtering text files and streams. sed offers an extensive set of robust commands and other features, including addresses for precise edit targeting, backups, and external script processing, that supercharge your text editing. To get output, you just supply commands and conditions, then run it. Since it’s not interactive and doesn’t require much time for the editing process, it works quickly. After sed performs the specified operation on each line, it outputs the processed text to stdout or a file, then moves on to the next line. Sed reads input text from files or stdin, then edits the text line by line according to the provided conditions and commands. The input stream could be from pipelines or files. A stream editor takes in text from an input stream and transforms it into a specified output according to instructions. sed is a Unix text processing and manipulation CLI tool. This is what makes sed, or stream editor, so valuable. You need the ability to search and manipulate text on the command line, especially when performing repetitive tasks. Earthly integrates sed into its reproducible build processes. This article explains how to use sed for text manipulation.
