The sed command is a bit like chess: it takes an hour to learn the basics and a lifetime to master them (or, at least a lot of practice). We'll show you a selection of opening gambits in each of the main categories of sedfunctionality. sed is a stream editorthat works on piped input or files of text. It doesn't have an interactive text editor inter...
First, we're going to use echo to send some text to sed through a pipe, and have sedsubstitute a portion of the text. To do so, we type the following: The echo command sends "howtogonk" into sed, and our simple substitution rule (the "s" stands for substitution) is applied. sedsearches the input text for an occurrence of the first string, and will ...
We're going to need a text file for our examples. We'll use one that contains a selection of verses from Samuel Taylor Coleridge's epic poem "The Rime of the Ancient Mariner." We type the following to take a look at it with less: To select some lines from the file, we provide the start and end lines of the range we want to select. A single number s...
In our first example, we showed you the following basic format for a sedsubstitution: The s tells sedthis is a substitution. The first string is the search pattern, and the second is the text with which we want to replace that matched text. Of course, as with all things Linux, the devil is in the details. We type the following to change all occurre...
Let's give Coleridge a break and use sed to extract names from the etc/passwdfile. There are shorter ways to do this (more on that later), but we'll use the longer way here to demonstrate another concept. Each matched item in a search pattern (called subexpressions) can be numbered (up to a maximum of nine items). You can then use these numbers in ...
We can also insert new lines and text into our file. To insert new lines after any matching ones, we'll use the Append command (a). Here's the file we're going to work with: cat geeks.txt We've numbered the lines to make this a bit easier to follow. We type the following to search for lines that contain the word "He," and insert a new line beneath ...
The Delete command (d) deletes lines that match a search pattern, or those specified with line numbers or ranges. For example, to delete the third line, we would type the following: To delete the range of lines four to five, we'd type the following: To delete lines outside a range, we use an exclamation point (!), as shown below:
So far, all of our results have printed to the terminal window, but we haven't yet saved them anywhere. To make these permanent, you can either write your changes to the original file or redirect them to a new one. Overwriting your original file requires some caution. If your sedcommand is wrong, you might make some changes to the original file tha...
As you've probably noticed, even this quick primer on sed is quite long. There's a lot to this command, and there's even more you can do with it. Hopefully, though, these basic concepts have provided a solid foundation on which you can build as you continue to learn more.
Learn how to edit text in files and streams with sed, a powerful text editor without an interface. Sed relies on regular expressions for pattern matching and text selection, and can perform substitutions, insertions, deletions, and more.
