Chapter 5. Finding Files and Information

One of the fundamental challenges with modern computers is finding files and information. Whether you're highly organized and use wonderfully mnemonic names for every file or directory created, or whether you have lots of letter1, letter2, and work directories scattered around your filesystem, there will undoubtedly come a time when you need to find something on your computer based on its contents, filename, or similar attribute.

It turns out that there are four different ways in Unix to search for—and hopefully find—what you seek. To look inside files, you need to use the grep command, as introduced briefly in the previous chapter. To find files by filename, the fastest solution is the locate command. A more sophisticated filename and attribute search can be done with the Unix power-user's find command. And finally, Tiger introduces an entirely new search system called Spotlight that has a powerful command-line component worth exploring.
