slackcat [-c channel] [-m message] [options] [file]

slackcat pipes command-line output and files directly to Slack channels, bridging terminal workflows with team communication. It accepts input from stdin, command arguments, or file uploads, sending the content as messages or file snippets to a specified channel.
Stream mode (--stream) sends output continuously as it arrives, useful for tailing log files into Slack in real time. Tee mode (--tee) simultaneously prints output to stdout and sends it to Slack, preserving normal terminal behavior while sharing with the team.
