ok - a super CLI with super powers

macOS options:

• Go toolchain (requires Go 1.22+):

  go install github.com/antick/ok@main

  Ensure your $GOPATH/bin (usually $HOME/go/bin) is on PATH:

  echo 'export PATH="$HOME/go/bin:$PATH"' >> ~/.zshrc && source ~/.zshrc

• Local build:

  git clone https://github.com/antick/ok.git
  cd ok
  go build -o ok .
  ./ok help

• From GitHub Releases (when available):

  1. Download the latest ok binary for macOS (arm64 or amd64) from the Releases page.
  2. Make it executable and place it on your PATH:

     chmod +x ok && mv ok /usr/local/bin/ok

Common commands:

ok copy <source> [to] <destination>
ok build <input_file> [as/to] <output_file>
ok move <source> [to] <destination>
ok remove <file_or_directory> [--permanent|-p]
ok docker
ok kill [--port] <port>

Find and kill processes listening on a TCP port. This uses lsof under the hood (equivalent to lsof -iTCP:<port> -sTCP:LISTEN), shows the list of matching processes, and asks for confirmation before killing with SIGKILL (-9).

Examples:

# Find what is using port 3000 and kill after confirmation
ok kill --port 3000

# You can also specify the port as a positional argument
ok kill 3000

# If you omit the port, the help menu is shown
ok kill

Behavior:

• Shows a table of processes (COMMAND, USER, PID, NAME) using the port.
• Prompts: Proceed to kill them? [Y/n]: Enter defaults to Yes.
• Uses SIGKILL to ensure processes exit.
• If nothing is listening, it prints a friendly message.

Notes:

• Requires lsof (available by default on macOS).
• You may need elevated privileges to kill some processes.

It creates ~/.ok/config.yaml file to set preferred defaults.

• If installed via Go:

  go install github.com/antick/ok@main

  This fetches and installs the latest version from main branch.
• If installed from GitHub Releases: re-download the latest binary and replace the existing /usr/local/bin/ok.
