Запуск командной строки
Наиболее часто встречающиеся рекомендации по запуску звучат так: Пуск, выполнить, cmd
. В меню пуск присутствует пункт Выполнить
. Он запускает программу, которая позволяет передавать единичные команды системе Windows. В данном случае команда cmd запускает исполняемый файл cmd.exe, находящийся в папке system32.
C:\WINDOWS\system32\cmd.exeНа некоторых версиях Windows пункт меню выполнить
по умолчанию убран. В этом случае жмёте + R, вводите cmd, далее Enter. Также можно запустить командную строку непосредственно из папки system32, сделав ярлык для запуска на рабочем столе (кликаем на cmd.exe правой клавишей мыши и в меню выбираем пункт Отправить/Рабочий стол
) или же через диспетчер задач (кнопка новая задача
— cmd).
По умолчанию в командной строке нельзя работать мышью (перемещать курсор или выделять текст). Это неудобно вообще и новичкам в особенности. К тому же чёрный экран выглядит как-то слишком мрачно и уныло. Поэтому после запуска командной строки
нужно будет изменить её настройки. Жмём правой клавишей на окне cmd и выбираем умолчания
. Стоит сразу отметить, что настройки умолчаний относятся к cmd.exe в целом, а свойства
— к конкретному открытому окну.
В появившемся окне свойств командной строки видим четыре вкладки:
На вкладке Параметры
стоит отметить пункты отбрасывать повторения
(чтобы снизить заполнение буфера команд) и выделение мышью
(чтобы можно было использовать мышь в работе).
На вкладках Шрифты
и Цвета
всё просто: выбираете размер, тип и цвет шрифта, а также фоновый цвет окна. Отмечу только, что размер шрифта влияет на размеры окна командной строки, поэтому его надо выставлять до размеров окна, а не после.
Во вкладке Расположение
задаются размеры окна и его начальное расположение при запуске. Я так до конца и не понял в каких единицах представлены величины, поэтому размер советую выставлять, руководствуясь окном предпросмотра слева.
Стоит отметить, что размер буфера влияет на вместимость окна, т.е. на количество информации, которое без проблем можно будет просмотреть после вывода на экран результатов выполнения команды (горизонтальная и вертикальная полосы прокрутки). Если задать равные размеры для окна и буфера, то в окне будет отображаться только хвост
выводимой информации, который туда вместится.
Также если строка не впишется в ширину окна это приведёт к её переносу. Воспринимать представленную таким образом информацию менее удобно. Поэтому буфер я ставлю всегда намного больше размеров окна. Это позволяет просмотреть большие объёмы информации, воспользовавшись полосами прокрутки справа и снизу. Картинка ниже кликабельна. На превью показано начало вывода команды dir для папки system32, а нажав на превью можно увидеть хвост
вывода (обратите внимание на полосу прокрутки справа — данных очень много).
Команды командной строки
Консоль настроена, теперь осталось ознакомить вас с командами командной строки. Для вывода их полного списка достаточно набрать команду help.
help - вывод справки по командам
help CD или CD /? - вывод справки по одной команде (для команды CD)
cd - переход в корневой каталог
cd .. - переход в родительский каталог
D: - переход на диск D.
dir - вывод всего содержимого папки
dir *.exe - вывод списка exe-файлов папки
cls - очистить экран командной строкиКомандная строка запоминает команды, которые вы вводите. Листать их можно клавишами ⇑ и ⇓. Можно просматривать содержимое папки при помощи клавиши Tab (Shift+Tab листает в обратном порядке). Можно пролистать файлы на конкретную букву или буквы. Например, напечатав букву s и нажимая Tab, можно пролистать только файлы и папки, начинающиеся на эту букву (system, system32, system.ini и т.д.) . Как это можно использовать:
Например, вам надо перейти из корня диска C в папку system32, найти и запустить в ней контрольную панель. Можно просто напечатать:
C:\windows\system32\control.exeНо это не всегда быстро и удобно, к тому же не всегда знаешь – что конкретно надо набирать. Поэтому можно набрать команду cd, затем после пробела набрать wi, пролистать клавишей Tab до папки Windows, поставить после неё слэш, набрать буквы sy, пролистать клавишей Tab до папки system32, затем опять слэш и то же самое с control.exe.
C: cd windows\system32\control.exe
Этот способ с табом куда быстрее в большинстве случаев, чем простой набор, так как названия файлов и папок могут быть длинными.
При включении поддержки мыши копировать информацию из командной строки можно выделив участок текста мышью и нажав Enter. Правая клавиша мыши, напротив, вставляет информацию из буфера обмена в командную строку.
В заключение статьи скажу, что cmd.exe — это просто программа ввода-вывода, такая же, как и блокнот. Разумеется, есть более продвинутые аналоги, которыми тоже можно пользоваться. Одна из таких программ — Console Portable
Кстати, в операционной системе GNU Linux командную строку можно вызывать прямо из папки. При этом строка откроется сразу с адресом папки и его не надо будет набивать вручную. В Windows для того, чтобы открыть командную строку непосредственно в папке, необходимо, зажав Shift, нажать правую клавишу мыши и выбрать в меню пункт «Открыть окно команд».
Также можно добавить эту возможность (и целый ряд других) с помощью программы расширения контекстного меню FileMenu Tools:

Работа на компьютере всегда сопряжена с некоторым риском, особенно если вы падки на различные эксперименты с операционной системой. В этом небольшом материале вы узнаете, что делать, если вы случайно удалили командную строку Windows (cmd.exe).
Несмотря на умышленное отсутствие развития терминала Windows с начала 2000-x и недавнее появление PowerShell, командная строка — это один из важнейших компонентов, отвечающих за работу ОС. Например, запуск всех файлов формата .bat и установка обновлений ОС осуществляется напрямую через cmd.exe. Но что делать, если вы случайно удалили командную строку Windows?
1. Открываем «Мой Компьютер» и переходим в папку Windows.
2. Вводим в быстрый поиск cmd.exe или переходим по пути C:\Windows\SysWOW64 и копируем найденный файл. Всё дело в том, что логика работы современных версий Windows не меняется годами, и для функционирования ОС, даже в 64-бит изданиях, используются по умолчанию устаревшие 32-бит версии программ.
3. Вставляем скопированный файл терминала в папку System32. Найти её можно по пути C:\Windows\System32.
Если всё было сделано правильно, то при попытке запуска терминала Windows через правый клик по меню «Пуск» появится всеми узнаваемое привычное чёрное окно.
Или же вы можете попробовать скачать оригинальные файлы терминала Windows с файлообменника и распаковать их в выше указанные папки. Но тогда я не гарантирую их работоспособность.
- Скачать (Яндекс диск)
- Скачать (Гугл диск)
- Скачать (MediaFire)
- Проверка на вирусы (VirusTotal)
В принципе, на этом всё! Конечно, можно было бы попробовать запустить через PowerShell с помощью команды Repair-WindowsImage-Online-RestoreHealth восстановление компонентов ОС, но тогда бы слетели бы все настройки Windows. По-этому не повторяйте моей ошибки и не экспериментируйте с файлами внутри папки ОС. Уважайте свободу, используйте только проверенное ПО и ни в коем случае не позволяйте компаниям диктовать вам свои условия. С вами был Павел. Ещё увидимся!
The genuine cmd.exe file is a software component of Microsoft Windows Operating System by .
The genuine Microsoft command line prompt utility, «Cmd.exe», formerly called ‘MS-DOS Prompt’, resides in «C:\Windows\System32.» When simply executed without parameters, it opens the Win32 console to accept and interpret commands entered by the user, (cd, runas, shutdown, ipconfig, ping, nslookup, and others), and display results. Once the console window opens, «cmd.exe» can be used within it but must have parameters. Its parameters give it power and versatility, allowing use of it in scripts to execute batch («.bat») or application («.exe») files. Information about its parameters and uses can be viewed in the console via «cmd /?», or via the Internet.

Best practices for resolving cmd issues
A clean and tidy computer is the key requirement for avoiding problems with cmd. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows’ 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.
Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
To help you analyze the cmd.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
