- Introduction to grep command under CentOS
- grep is a command line tool originally used in Unix operating systems. Given a file list or standard input, grep will search for text that matches one or more regular expressions and output only matching (or unmatched) lines or text. grep can query matching lines in the file based on the provided matching pattern list. After a matching line is found, the line content will be output to standard output (default). If other parameters are used, output in other formats can be generated. grep is used to match text. It There is no limit on the length of the input line, except by available memory, and any character within the line can be matched.

- Powerful grep command
- There are a lot of explanations about the grep command on the Internet, and they are basically a rough translation of the man command. To be honest, I will forget it after reading it! Personally, I think the best way to learn commands is to simulate the real environment, write down some command combinations that may be used, and then slowly digest them. At least that's how I came here. At the beginning, it was basically rote memorization, and then I slowly expanded my horizons. As time went by, I accumulated more. Okay, let’s get to the point and talk about the awesome grep command.
