SYNOPSIS

plink [options] [user@]host [command]

plink is the command-line SSH connection tool from the PuTTY suite. It provides non-interactive SSH access for executing remote commands, port forwarding, and scripted SSH operations.
Unlike the interactive PuTTY terminal, plink is designed for automation and batch operations. It supports SSH key authentication using PuTTY's .ppk key format. The -batch flag disables all interactive prompts, making it suitable for scripts and cron jobs.
