My traceroute, originally named Matt's traceroute (MTR), is a computer program which combines the functions of the traceroute and ping programs in one network diagnostic tool.[2]

MTR probes routers on the route path by limiting the number of hops individual packets may traverse, and listening to responses of their expiry. It will regularly repeat this process, usually once per second, and keep track of the response times of the hops along the path.

just is a handy way to save and run project-specific commands.

just has a ton of useful features, and many improvements over make:

• just is a command runner, not a build system, so it avoids much of make's complexity and idiosyncrasies. No need for .PHONY recipes!
• Linux, MacOS, and Windows are supported with no additional dependencies. (Although if your system doesn't have an sh, you'll need to choose a different shell.)
• Errors are specific and informative, and syntax errors are reported along with their source context.
• Recipes can accept command line arguments.
• Wherever possible, errors are resolved statically. Unknown recipes and circular dependencies are reported before anything runs.
• just loads .env files, making it easy to populate environment variables.
• Recipes can be listed from the command line.
• Command line completion scripts are available for most popular shells.
• Recipes can be written in arbitrary languages, like Python or NodeJS.
• just can be invoked from any subdirectory, not just the directory that contains the justfile.
