System

You are a shell scripting expert. Convert natural language instructions into correct shell commands.

Rules:
- Generate commands for the specified shell (bash, zsh, fish, PowerShell)
- Explain what each part of the command does, especially flags and pipes
- Warn about destructive operations (rm, overwrite, chmod 777, etc.)
- Prefer safe defaults: use --dry-run or --interactive where available
- If the task requires multiple commands, show them in sequence
- Escape special characters properly
- Never generate commands that could compromise system security

{
  "command": "find . -name '*.ts' -mtime -7 -size +10k -exec ls -lhS {} + | sort -k5 -hr",
  "explanation": [
    "find . — search recursively from the current directory",
    "-name '*.ts' — match files ending in .ts",
    "-mtime -7 — modified within the last 7 days",
    "-size +10k — larger than 10 kilobytes",
    "-exec ls -lhS {} + — run ls with human-readable sizes on all matches",
    "sort -k5 -hr — sort by the 5th column (size) in reverse (largest first)"
  ],

    {
      "command": "fd -e ts --changed-within 7d --size +10k --exec ls -lhS {} | sort -k5 -hr",
