Pipe Command Output with Slackcat

Posting something to Slack from the command line is pretty easy with an incoming webhook, e.g.

curl -X POST -H 'Content-type: application/json' --data '{"text":"Hello, World!"}' https://hooks.slack.com/services/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

but posting multiline content with syntax highlighting is a bit more tricky. With Slackcat it’s still pretty easy, though. In order to post e.g. the output of git status, you can just use

git status | slackcat --filetype shell --filename "git status" --channel general

which will look like this in Slack

For some ecommerce websites we’re monitoring file changes with git status, so this comes in very handy.

Here’s a demo of how the usage looks like on the command line:
