This article mainly introduces the relevant knowledge of what functions ripgrep has, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading this ripgrep article. Let's take a look at it.

First, `grep` is a line search tool that we use almost every day in Linuxer, and almost all distributions come with this tool. For many years, nothing has changed, such as a pool of stagnant water. The emergence of `ripgrep` has brought a sensation to this field.

Ripgrep is very good, and now its github is close to 14000 stars.

The first point that ripgrep surpasses grep is that ripgrep is cross-platform and no longer discriminates against Windows users. Windows and Linux,macOS have the same effect.

Second, have a more beautiful output.

Of course, the question of beauty is hard to tune.

Third, strong performance.

It's a mule or a horse. Take it out for a walk.

Comparison 1:

Search for Linux kernel source files (after executing make defconfig & & make-J8), CPU Intel i7-6900K 3.2 GHz,ripgrep has SIMD support.

Comparison 2:

(ucg has a different strategy when dealing with symbolic links.)

Comparison 3:

Why ripgrep is recommended

Because it covers most of the features of other similar search tools and is faster.

Ripgrep recognizes the .gitignore file and ignores the files and directories specified in it. Hidden files and directories are not searched by default. Binaries are not searched by default.

Ripgrep can specify to search for certain types of files. For example, rg-tpy foo only searches for py files, while rg-Tjs foo excludes js files when searching.

Ripgrep supports Unicode.

PCRE2 can be selected as the regular engine.

Support the search of non-UTF-8 files.

Support the search of files in the compressed package.

Any preprocessing filter is supported.
