locate-anything.cpp: Fast File & Content Search for Your CLI

Introduction

In the command-line world, developers live by two fundamental search commands: locate for finding files by name instantly, and grep or ripgrep for searching inside their contents. While both are incredibly fast at their respective tasks, they operate in separate worlds. What if you need the indexed speed of locate for both filenames *and* their contents? This is the exact problem that locate-anything.cpp, a blazing-fast C++ utility, is designed to solve. With a growing community and over 200 GitHub stars, it unifies these two search paradigms into a single, powerful tool.

What Is locate-anything.cpp?

locate-anything.cpp is an open-source, command-line tool for finding files on a system by indexing both their names and, optionally, their full-text content. As the name suggests, it is a high-performance C++ implementation of the original `locate-anything` project, rewritten from the ground up for maximum speed and simplicity. Developed by mudler, the entire tool is a single, self-contained executable with no external runtime dependencies, making it lightweight and portable.

The project’s philosophy is simple: create a database of your files once, then search it instantly. By using multi-threading for the initial indexing and a compact database format, it provides near-instantaneous search results for even massive filesystems. It’s released under the permissive MIT license, making it completely free for anyone to use and modify for any purpose.

Why locate-anything.cpp Matters

The real power of locate-anything.cpp is its hybrid approach. Traditional tools force a choice. You can have an index of filenames (mlocate), which is fast for finding files but blind to their content. Or you can perform a live, non-indexed search of file contents (ripgrep), which is incredibly fast for what it does but still has to read files from disk every time. This means finding a file based on a variable name inside it across your entire home directory can still be a slow process.

locate-anything.cpp eliminates this trade-off. By creating an index of file contents ahead of time, it brings the ‘instant’ search speed of `locate` to the world of full-text search. This is a game-changer for developers working in large codebases, system administrators managing complex configurations, or anyone who frequently needs to find files based on what’s inside them. It unifies two distinct, everyday workflows into a single, cohesive, and incredibly fast tool.

Key Features

Blazing-Fast C++ Performance: Being written in C++ and compiled to a native binary, the tool operates with minimal overhead and maximum speed for both indexing and searching.
Unified Filename and Content Indexing: The core feature is its ability to create a single database that contains information about file paths and their full-text content, allowing you to search both at once.
Multi-Threaded Indexing: It leverages all available CPU cores to make the initial indexing process as fast as possible. You can control the number of threads with a simple command-line flag.
Instantaneous Search Results: Once the index is built, searches are performed against the database file, returning results almost instantly without needing to touch the filesystem.
Simple, Intuitive CLI: The command-line interface is straightforward and easy to learn, with clear flags for creating, updating, and searching the database.
Optional Full-Text Search: You can choose whether to create a simple filename-only index or a more comprehensive index that includes file contents, giving you control over the database size and indexing time.

How locate-anything.cpp Compares

To understand the unique value of locate-anything.cpp, it’s best to compare it against the established tools in the file-searching space.

Feature	locate-anything.cpp	mlocate / plocate	ripgrep (rg)	fd
Search Type	Indexed	Indexed	Live Search	Live Search
Search Target	Filenames & Contents	Filenames Only	Contents (Primarily)	Filenames Only
Search Speed	Instant	Instant	Very Fast (for live)	Very Fast (for live)
Key Differentiator	Indexed full-text search	Standard, system-wide name index	Fastest live content search	Modern, user-friendly `find` alternative

The table makes its niche clear. mlocate is the classic standard, but it can’t see inside files. ripgrep is the undisputed champion of live content search, but it isn’t indexed, meaning it re-scans files every time. fd is a fantastic tool for finding files by name and metadata without an index, but it also doesn’t search content.

locate-anything.cpp is the only tool in this list that provides an indexed, and therefore instant, search for both filenames and their contents. This makes it the ideal solution for frequent searches across large, relatively static sets of files, such as a large codebase or a personal document archive.

Getting Started: Installation

You can get started with locate-anything.cpp either by downloading a pre-compiled binary or by building it from source.

Method 1: Using Pre-compiled Binaries (Recommended)

The easiest way to install the tool is to download a binary for your system.

Go to the official GitHub Releases page.
Find the latest release and download the appropriate binary for your operating system and architecture (e.g., `locate-anything-linux-amd64`).
Make the binary executable: chmod +x./locate-anything-linux-amd64
Move it to a directory in your PATH: sudo mv./locate-anything-linux-amd64 /usr/local/bin/locate-anything.cpp

Method 2: Building from Source

If a binary isn’t available for your system, you can compile it yourself.

Prerequisites: You will need git, cmake, and a C++ compiler (like g++).

# 1. Clone the repository
git clone https://github.com/mudler/locate-anything.cpp.git
cd locate-anything.cpp

# 2. Create a build directory
mkdir build
cd build

# 3. Configure and compile
cmake..
make

# 4. Install the binary
sudo make install

How to Use locate-anything.cpp

Using the tool is a two-step process: first, you create an index (the database), and second, you search against it. You can have multiple database files for different directories (e.g., one for your code, one for your documents).

Let’s say you want to index your projects directory located at ~/projects and save the database as projects.db.

Step 1: Create the Index

To create a simple filename-only index, run:

locate-anything.cpp -d projects.db -u ~/projects

To create a more powerful index that includes file contents, add the --content flag. You can also speed up indexing with the -j flag to specify the number of threads to use.

locate-anything.cpp -d projects.db -u ~/projects --content -j 8

Step 2: Search the Index

To search for a file by its name:

locate-anything.cpp -d projects.db "my_component.js"

If you indexed the content, you can now search for files containing a specific string. Use the -i flag for a case-insensitive search.

locate-anything.cpp -d projects.db -i --content "my_function_name"

This will instantly return a list of all files in your projects directory that contain that string.

Real-World Use Cases

Large Codebase Navigation: A developer can index their entire monorepo with content. Finding where a specific function or variable is defined becomes instantaneous, even across thousands of files.
System Configuration Management: A system administrator can index the /etc/ directory. Finding every configuration file that mentions a specific service name or IP address takes seconds.
Personal Document Search: Index your entire ‘Documents’ folder. You can then instantly find a PDF, text file, or Word document based on a phrase you remember from its content, even if you’ve forgotten the filename.
Log File Analysis: For a directory of log files, you can create a content index to instantly find every log entry that contains a specific error code or user ID without having to `grep` through gigabytes of text each time.

Conclusion

locate-anything.cpp is a powerful, focused utility that does one thing exceptionally well: it makes searching for files and their content incredibly fast. By cleverly combining the indexed approach of `locate` with the full-text capabilities of `grep`, it creates a new category of search tool that can dramatically speed up common developer and sysadmin workflows. Its simplicity and performance, thanks to its C++ core, make it a tool worth adding to any power user’s arsenal.

If you find yourself constantly switching between `locate` and `ripgrep`, or waiting for a slow search to complete, you owe it to yourself to give locate-anything.cpp a try. The initial time spent on indexing will pay for itself many times over with every instant search you perform afterward. It is a perfect example of a tool that respects your time.

Head over to the GitHub repository, download a binary, and try indexing a project directory. You might be surprised at how much faster your file searching can be.

What is locate-anything.cpp?

locate-anything.cpp is a command-line tool written in C++ that creates an index of your files to make searching for them extremely fast. Its key feature is the ability to index not only filenames but also the full-text content of those files, allowing for instant searches of both.

How is it different from the standard 'locate' command?

The standard `locate` (or `mlocate`) command only indexes filenames and paths. It is very fast for finding files by name but cannot search for their content. locate-anything.cpp can do both, letting you find a file based on a word or phrase inside it, with the same indexed speed.

How does locate-anything.cpp compare to ripgrep (rg)?

ripgrep is a tool for performing live searches of file contents; it reads files from the disk every time you run a search. locate-anything.cpp works differently by first creating a content index. This makes the search itself instantaneous, which can be much faster than ripgrep for repeated searches over large sets of files, at the cost of needing to build the index upfront.

How do I search file contents?

To search file contents, you must first create an index with the `–content` flag (e.g., `locate-anything.cpp -d db.dat -u. –content`). Once the index is built, you can search it using the same `–content` flag (e.g., `locate-anything.cpp -d db.dat –content “search term”`).

Is locate-anything.cpp free to use?

Yes, it is completely free and open-source. The project is distributed under the MIT License, which allows for use, modification, and distribution for any purpose, including in commercial environments.

How often do I need to update the index?

You should update the index whenever you have made significant changes to the files in the indexed directory. You can update it by running the same command you used to create it, for example: `locate-anything.cpp -d db.dat -u.`. It will intelligently scan for changes rather than rebuilding from scratch unless you use the `–rebuild` flag.

Can I use locate-anything.cpp on Windows or macOS?

Yes. The project provides pre-compiled binaries for Linux, and you can compile it from source on other platforms like macOS and Windows that have a C++ compiler and CMake. Check the GitHub Releases page for available binaries.
