The Missing Tool

The Missing Tool is a command line program that fills in the gaps in your command line experience. It provides lots of handy little utilities that your command line is missing, like:

• A killport that kills a process by port number (how has this not been a standard command?)
• A ports command that lists all listening ports
• A port command to describe the process listening on a port
• A watch command that runs a command every X seconds
• A restart command that restarts a command when it exits
• A selector web server that lets you browse and select images to move
• A network-info command that shows network details in a format that doesn't make me hate my existence
• A http-logger that logs HTTP requests
• A find for systems that don't have it
• A ssh-key command that copies your SSH public key to a remote server for automatic login
• A image-check command that scans directories for images and verifies they are uncorrupted
• A combine-files command that concatenates files from a directory into a single file
• A relay command that relays TCP connections to a remote server
• A relay-ipv6 command that listens on ipv6 addresses and relays to ipv4 addresses

It is written in Go, and is available on github.
