Sometimes, you want the lines only below, including the matched one. There can be times when you only want to see a few lines above, including the matched line. This option accepts a numerical value and shows lines before and after the match. The '-C' or '-context' option helps here.

Sometimes, it is nice to have a context of the matching line, especially when searching in a code repository. When you regularly search for a set of patterns to match, you can store it in a file and specify it using the '-file' option. If you specify multiple files to search for (if you don't specify any files, it will search for all), ripgrep will also determine the filename whose contents matched.Īlternatively, you can also use the '-file' option, which contains the pattern you want to match. Basic searchesĪ sample search of the word description in the Cargo.html file: $ rg description Cargo.tomlģ:description = "A more intuitive version of du"Īs expected, the ripgrep tool searched in the file that I specified and displayed the files with matching text and the line number. You provide it with a search string and a filename, and it will search the file and show you where the input string matched with the file contents.įor this tutorial, I have cloned the repository of the dust project, and I will be executing the commands inside the cloned repository. If you are familiar with grep command usage, you'll find ripgrep works similarly.

While grep comes preinstalled on most Linux systems, ripgrep doesn't have that privilege. You can think of it as grep, but primarily aimed at searching for files/content of files instead of the raw byte stream that grep deals with.

If you have specific files, extensions, or directories in your gitignore, ripgrep will ignore them, speeding up execution time.Ī few features that make ripgrep stand out are as follows: Ripgrep is a recursive regex pattern matching tool that considers your gitignore.

You may also use grep to search in all files but ripgrep does it without any additional effort. This is incredibly helpful if you do not know which file contains the pattern you search. When a file name is not provided, all files are searched. With ripgrep, there is no need to mention a file name. The syntax to use ripgrep is as follows: rg It is intended to be a superior replacement for the classic grep command. Ripgrep is an excellent outcome of the RIIR (re-write it in Rust) effort going on in the open source community.
