Низкое дисковое пространство & ldquo; Корневая файловая система & rdquo;

Вы можете использовать подавляющее большинство зарезервированных слов bash и операторы управления, чтобы спровоцировать синтаксическую ошибку - давайте сделаем быстрый тест, чтобы получить (конечно же неполный!) список:

$ tabs 10
  for i in '|' '&' ';' '(' ')' '<' '>' '||' '&&' \
           ';;' '|&' 'case' 'coproc' 'do' 'done' \
           'elif' 'else' 'esac' 'fi' 'for' 'function' \
           'if' 'in' 'select' 'then' 'until' 'while' \
           '{' '}' '[[' ']]';
  do
    printf "%s\t" "$i"; bash -c $i |& sed '2d;s/.*://'
  done
