[BUG] Bash tool commands execute but produce no output and file operations don't persist

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

• Commands like pwd, ls -la, echo, docker ps, python3 -V all return [No output] instead of displaying their output
• File redirection operations (e.g., echo "lmao" > ./test_pipe) appear to execute without errors but don't actually create files
• The Write/Read tools work correctly, suggesting the issue is specific to the Bash tool

What Should Happen?

Bash commands should display their output and file operations should persist

Error Messages/Logs

I didn't see anything.

Steps to Reproduce

1. Run: echo "test" > ./test_file
2. Run: ls -la ./test_file
3. Result: [No output] but file doesn't actually exist
4. Verify with Read tool - file not found
