GitHub workflow commands for message output

Use the :: syntax to run the workflow commands within your YAML file; these commands are then sent to the runner over stdout.

Message output

Note

Requires debug logging enabled.

::debug::{message}

Example debug messages

run: echo "::debug::Set the Octocat variable"

Notice

Creates a notice message and prints the message to the log. This message will create an annotation, which can associate the message with a particular file in your repository. Optionally, your message can specify a position within the file.

::notice file={name},line={line},endLine={endLine},title={title}::{message}

Example notice messages

run: echo "::notice file=app.js,line=1,col=5,endColumn=7::Missing semicolon"

run: echo "::notice title=Heads up::I need to make you aware of something"

run: echo "::notice title=✓ Test passed::Have a great rest of the day/night!"
