Мне нужно удалить все профили с use_profile 0 и use_group 0 с помощью сценария bash или любого другого сценария, который я могу запустить в системе Linux. Я играл с awk, grep и sed, но не добился никакого прогресса.

Мне нужно превратить вышеупомянутое в нижеследующее. Любые советы, советы о том, какие инструменты использовать, или демонстрация мне того, как они были бы очень оценены.

Ваш вопрос очень похож на Печатать весь абзац в файле по шаблону, только в вашем случае это разделы текста, разделенные .. , а вы хотите наоборот (т.е. удалить соответствующий раздел). Вы можете адаптировать любое из решений к вашим потребностям, например. с sed : 

sed '/<kernel>/!{H;$!d;};x;/\nuse_profile 0\nuse_group 0\n/d' infile

или, если вашему sed не нравится этот синтаксис: 

sed -e '/<kernel>/!{H;$!d' -e '}' -e 'x;/\nuse_profile 0\nuse_group 0\n/d' infile

awk подход: 

awk 'BEGIN{fn="use_profile_output";}/<kernel>/{getline up; if(up~/use_profile [1-9][0-9]*/)
     {f=1; print $0 RS up > fn; next }else{ f=0 }}{ if(f) print > fn; }' file

fn="use_profile_output" - переменная fn(имя файла), содержащая use_profile_output в качестве результирующего имени файла для всех блоков , содержащих use_profile без последующего нуля 0

// - при каждой встрече со строкой, содержащей ключевое слово будет выполняться следующий набор фигурных скобок

getline up; - получает следующую запись, содержащую ключевое слово use_profile, и присваивает ее переменной up

use_profile_output содержимого файла (некоторые строки были опущены для отображения компактного вывода): 

<kernel> /usr/sbin/ntpdate
use_profile 3
use_group 0

misc env LS_COLORS
misc env LANG

misc env LC_CTYPE
