This article lists the most common grep commands with quick examples. Linux Handbook already has a detailed article on grep, so I won't go in depth here. I'll just the common options and their explanation here.

One of the classic Unix commands, developed way back in 1974 by Ken Thompson, is the Global Regular Expression Print (grep) command. It's so ubiquitous in computing that it's frequently used as a verb ("grepping through a file") and, depending on how geeky your audience, it fits nicely into real-world scenarios, too. (For example, "I'll have to grep my memory banks to recall that information.") In short, grep is a way to search through a file for a specific pattern of characters. If that sounds like the modern Find function available in any word processor or text editor, then you've already experienced grep's effects on the computing industry.

It's useful to be able to find text in a file, but the true power of POSIX is its ability to chain commands together through "pipes." I find that my best use of grep is when it's combined with other tools, like cut, tr, or curl.

The grep command has far more options than I demonstrated in this article. There are options to better format results, list files and line numbers containing matches, provide context for results by printing the lines surrounding a match, and much more. If you're learning grep, or you just find yourself using it often and resorting to searching through its info pages, you'll do yourself a favor by downloading our cheat sheet for it. The cheat sheet uses short options (-v instead of --invert-matching, for instance) as a way to get you familiar with common grep shorthand. It also contains a regex section to help you remember the most common regex codes. Download the grep cheat sheet today!

The simple grep command requires two arguments: pattern to search and file name. grep is a case sensitive tool, you have to use correct case when searching through grep commands. It prints the whole line that contain matching patterns until the line breaks occur. If there are no any matching patterns, it prints nothing.

grep -h command hides the file name in the output. grep command normally shows file names when there are matched patterns in multiple files. You can use any commands that search in multiple files.

These are the most important grep commands that contain different options available. By using these commands, you can find the specific characters in large files easily. You can also combine different options in grep command to create variations in your search. So, grep is a powerful tool that can be used in the terminal of Linux systems.

This is a command injection prevention cheat sheet by r2c. It contains code patterns of potential ways to run an OS command in an application. Instead of scrutinizing code for exploitable vulnerabilities, the recommendations in this cheat sheet pave a safe road for developers that mitigate the possibility of command injection in your code. By following these recommendations, you can be reasonably sure your code is free of command injection.
