Post to bsky from the CLI.md 
http \
  POST \
  https://bsky.social/xrpc/com.atproto.server.createSession \
  identifier=USERNAME.bsky.social \
  password=APP_SPECIFIC_PASSWORD

http \
  POST \
  https://bsky.social/xrpc/com.atproto.repo.createRecord \
  Authorization:"Bearer ACCESS_JWT" \
  repo=DID \
  collection=app.bsky.feed.post \
  record\[\$type\]=app.bsky.feed.post \
  record\[text\]="Test post please ignore" \
  record\[createdAt\]="$(date -Iseconds)"

Copy the ACCESS_JWT and DID from the response of the createSession call (in real code, you'd store the response in a variable).

These resources helped me put this together:
