Additional info for Introducing Regular Expressions

Example text

Open the RegExr desktop application by double-clicking on its icon. It looks very much like the online version but has the advantage of being local on your machine, so you won’t suffer the network issues that sometimes occur when using web applications. 41 I’ve copied and pasted the entire poem in RegExr desktop for the next exercise. I’m using it on a Mac running OS X Lion. In the top text box, enter the pattern: (the|The|THE) and you’ll see all occurrences of the in the poem highlighted in the lower box (see Figure 4-1).

We have to look beyond the browser for that. Adding Tags with sed On a command line, you could also do something similar to what we just did in RegExr with sed, which you saw in the last chapter. The insert (i) command in sed allows you to insert text above or before a location in a document or a string. By the way, the opposite of i in sed is a, which appends text below or after a location. We’ll use the append command later. txt The backslashes (\) at the end of the lines allow you to insert newlines into the stream and not execute the command prematurely.

This syntax also works with grep. Since the early 1970s, grep like sed has been a Unix mainstay. txt The -E option indicates that you want to use extended regular expressions (EREs) rather than the basic regular expressions (BREs) which are used by grep by default. The -o option means you want to show in the result only that part of the line that matches the pattern, and the -c option means only return a count of the result. The pattern in single quotes will match either THE, The, or the as whole words.
