ls-having is a powerful open-source tool that makes it easy to find directories. With a simple and intuitive command-line interface, "ls-having" allows you to quickly search for directories based on specified flag files and other conditions, saving you time and effort. Whether you're a developer who works with mono repos, or you just need an easy way to find your directories, "ls-having" is the perfect tool for you.

• Flexible search options: "ls-having" allows you to specify various options and conditions for searching for directories, such as flag files, the check file, regular expressions for matching the check file, excludes, and maximum depth.
• Configurable error handling: "ls-having" provides an option for configuring how it handles errors such as non-existing directory or no access permission, allowing users to customize and integrate the tool for different situations.
• Cross-platform support: "ls-having" is available for Linux, MacOS, and Windows.
• Small and quick: "ls-having" has just one native executable file, there is no dependency on anything else, and the tool is just about 2MB in size. It starts and runs very quickly.

Quick start

Try this:

ls-having -f package.json

This will search for directories containing a "package.json" file in the current directory and print the names of those directories to the console. You can then use the output of "ls-having" as arguments for other commands, such as "xargs", to perform actions on those directories.
