Describe the current, buggy behavior

Cannot add block content via the --post_content flag.

Describe how other contributors can replicate this bug

Try to create a post with block content

wp post create --post_title="Pizza Day" --post_status=publish --post_content="<!-- wp:paragraph --><p>PIZZA FRIDAY</p><!-- /wp:paragraph -->"

See error that the event is not found.

bash: !-: event not found

However

wp post create --post_title="Pizza Day" --post_status=publish --post_content="PIZZA FRIDAY"

inserts a post, though with "classic editor" content that then needs to be converted to blocks.

Hopefully this is just bad formatting on my part? In which case, we can switch this to a documentation request?

Describe what you would expect as the correct outcome

post inserted with block content ready for use in the block editor

This seems to be the issue with shell rather than WP CLI. Even echo "<!-- wp:paragraph --><p>PIZZA FRIDAY</p><!-- /wp:paragraph -->" gives that error. ! character is expected to be escaped. When you escape such character in the command, it works as expected.

wp post create --post_title="Pizza Day" --post_status=publish --post_content="<\!-- wp:paragraph --><p>PIZZA FRIDAY</p><\!-- /wp:paragraph -->"

I just tested your command in the CLI and it runs without error, however the content created is still not a block but the classic content. The escaped comment is still considered a string.

Found [this issue] which suggests importing escaped content via HTML file. don't know if I'll be able to do that in the blueprint.json, but I will try to test.

Above command is working fine for me. I am using WP-CLI 2.10.0.
