prompt="Convert this to a single POSIX shell command for Ubuntu. Output ONLY the raw command - no markdown, no backticks, no explanations, no extra text. Prefer common tools (grep, find, awk, sed, tar, zip, ffmpeg, imagemagick, pdfunite). Use safe default filenames if needed (output.pdf, result.txt). Avoid destructive operations unless explicitly requested.
