When searching, though, remember to indicate you’re looking for GREP in InDesign, since InDesign uses a subset of all that’s available GREP-wise. And lastly, doing a web search will often give you just what you need. Click that and you’ll find many of the expressions you’ll need, listed by their name or their function. When you’re creating a GREP expression, there is a little “at symbol” to the right of the various input fields. You don’t have to learn all of the wildcards and other GREP expressions because the folks at Adobe have gifted us with a handy resource: The Secret Menu. It can get a little confusing, but my modus operandi is simply to throw a backslash in front of an expression that isn’t working, or remove one if one exists. But if you’re looking for an actual period, then you throw the backslash in front of it. A period by itself indicates any character, from a letter to a number to a symbol to a tab space. For instance, probably the most common wildcard you will use is the teeny tiny period (also known as a dot or full stop). Conversely, backslashes are often used when you want to indicate the literal character itself. In terms of wildcard usage, they are there to distinguish the letter used in its special context from the literal meaning of the letter. One of the first things I noticed when learning GREP was the proliferation of backslashes. Note that some grep s (like GNU grep) wont require -E for this example to work. If you want to grep using more advanced regex, use -E (use extended regex): grep -E directory 1-3 file. Looking for a lowercase letter or an uppercase one? Use \l and \u, respectively. If those are the only strings you need to search for, use -F (grep for fixed strings): grep -F 'directory1 directory2 director圓 ' file.txt. In another article, I show you how to simplify this type of expression, but it’s perfectly possible to find a 10-digit string-a North American phone number, for example-with dddddddddd. ![]() When looking for two digits, you could write \d\d. As you build out your expression, you may find that you need two (or even more) of a particular wildcard. ![]() The Number Wildcardįor example, the wildcard that we would need when formatting a phone number, serial number, part number, etc is the one for “any digit.” This is expressed in GREP as \d. The more you work with GREP expressions, the more wildcards you’ll memorize because you’ll be using them so often in your expressions. Wildcards come into play when we need to write an expression that looks for any digit, as opposed to the number 3 specifically, for instance. That is, you don’t need to know exactly which numbers you’re looking for, just that you are, indeed, looking for numbers. Finding out what Exim processes are doing (exiwhat) On operating systems that can restart a system call after receiving a signal (most modern OS), an Exim process responds to the SIGUSR1 signal by writing a line describing what it is doing to the file in the Exim spool directory. GREP finds patterns based on generalities. This article is part of a series of posts on using GREP in InDesign for beginners
