In it he says, 'If there is one Unix command I would love to have in PowerShell, it is the grep command with its regular expression support.' Well Dustin, your wish is our command. Select-String command to be precise.

It's fast, it's powerful, and its very name suggests that it does something technical: grep. With this workhorse of the command line, you can quickly find text hidden in your files. Mods for doki doki. Understanding grep is the first step in joining the guild of command-line wizards.Why Not Use the Finder?It's easy to find files with the Finder when you know their names.

But the grep command is a time-saver when you're trying to find what's inside files. You can use grep easily from the command line to search for specific text, and you'll get results in seconds. (You can also use grep within.)The Finder offers a similar function: the Find By Content search. (Press Command-F in the Finder, select Content in the Search For Items Whose pop-up menu, and enter a search string in the text field.) But the Finder searches only inside files it has indexed, and it ignores hidden system files unless you expressly choose to search for visible and invisible files and add your System folder to the search. The Finder also lacks grep's flexibility: while it's good for searching for a specific word (for example, Walden ), it becomes less useful when you want to find a longer string. Search for Walden Pond, and it returns all files that contain either Walden or Pond.Using grep also gives you access to regular expressions. These combinations of letters, numbers, wild cards, and other special characters let you find much more than mere words.

You can search for just about any string of characters: IP addresses in log files; phone numbers in contact lists; or specific strings containing a series of numbers, letters, or other characters. Using regular expressions, you're limited only by your imagination.Get a Grip on GrepThe grep command looks inside one or several files for the string, or text, you specify. Its syntax is: grep options searchstring file.At its most basic, you tell grep what to look for and where: grep AppleTalk /etc/services, for example.

Here, you tell grep to look for AppleTalk in the services file located in the /etc directory. (This useful file contains a list of network port numbers for commonly used services.) The command displays each line that contains your search string:echo 4/ddp # AppleTalk Echo Protocolat-rtmp 201/udp # AppleTalk Routing Maintenanceat-rtmp 201/tcp # AppleTalk Routing MaintenanceAnd so on. You can use the familiar asterisk (.) wild card to have grep search a group of files in the current working directory, as in grep Walden. This command searches all the files in the current directory for the word Walden, returning the following:Binary file Walden.doc matchespepysdiary.txt:that spoke ill of him, and told me how basely Lionell WaldenExcursions.txt:veil over his experience. All readers of 'Walden' will remember hisWalden.txt:purpose in going to Walden Pond was not to live cheaply nor to live dearlyAnd so on.

As the above example shows, the search returns several matches. The first, Walden.doc, is a Word file. The grep command calls such proprietary file types binary files. It can't display the contents of binary files, but it can search inside them and tell you if something matches.

The next examples come from plain-text files, for which grep can display the results. You see the file name, followed by a match of the search string in its context.You can search for any multiword text string by enclosing the string in single quotes.

For example, if you want to search for the phrase Walden Pond,you'd type grep 'Walden Pond'.Note that grep doesn't like Macintosh line breaks. It returns lines containing the search string, but it doesn't see Mac line breaks as anything other than characters. In such a case, the “line” it returns is the entire file; this can dump a lot of text into your Terminal window.In the previous example, grep ran in a specific folder, checking all the files it contained. What if you want to run grep on a folder and its subfolders, or you want grep to look for the string regardless of case?

You need to add options. For example, to search for Waldenanywhere in a folder or its subfolders, use the -r(recursive) option: grep -r Walden /Documents/.
