CLAUDE_CODE_FORCE_FULL_LOGO

Updated October 13, 2026 by Alex Sorokoletov

CLAUDE_CODE_FORCE_FULL_LOGO is a Claude Code environment variable: Force full ASCII logo display on startup. Removed between v2.1.245 and v2.1.247, so current releases ignore it. It is not in the official reference.

How to set it

For one session, export it in the shell that starts Claude Code:

export CLAUDE_CODE_FORCE_FULL_LOGO=<value>
claude

To apply it to every session, add it to the env object of a settings file:

// ~/.claude/settings.json
{
  "env": {
    "CLAUDE_CODE_FORCE_FULL_LOGO": "<value>"
  }
}
