Что такое Cygwin

Вам когда-нибудь приходилось после linux’а пользоваться командной строкой Windows? Мне, да. Очень не привычно. Многие команды называются по-другому. Например, аналог ls в Windows это dir. Стилистика передачи аргументов у местного интерпретатора другая. А многих возможностей, которые дают линуксовые утилиты тут просто нет. Как-же получить аналогичную linux среду в windows? Это можно сделать установив Cygwin.

Знакомство с развернутой системой

Во-первых у cygwin по-умолчанию устанавливается свой эмулятор терминала, с которым работать по-удобнее, чем с командной строкой Windows.
emulator
Тут у нас первые проблемы. Как видите, windows утилиты, в том числе и cmd.exe печатают текст в oem-866, а эмулятор cygwin читает текст в utf-8. Если переключить кодировку на 866 кодовую страницу, то последствия этого действия еще хуже.
emulator-866
cygwin интерпретировал русскоязычное имя в unicode кодировке, как строку в 866 кодировке и в итоге решил создать новую директорию /home/╨Ф╨╝╨╕╤В╤А╨╕╨╣. Так что лучше все оставить как было и, при возможности обходиться cygwin утилитами. В случае, если вам нужно запустить командную оболочку без эмулятора терминала, запустите пакетный файл Cygwin.bat.
В данном случае, cygwin установлена в папке C:\cygwin64\. Узнать преобразуются пути из unix-path в windows пути нам поможет утилита cygpath.
$ cygpath -w `pwd`
C:\cygwin64\home\Дмитрий

$ cygpath -w /
C:\cygwin64

$ cygpath 'C:\cygwin64'
/

$ cygpath 'C:\cygwin64\home\Дмитрий'
/home/Дмитрий
А как получить доступ к диску C:, если все пути транслируются в C:\cygwin64\.
Все просто. В дирректории /cygdrive есть точки монтирования, которые по имени соответствуют томам windows.
$ cygpath 'C:\'
/cygdrive/c

$ cygpath -w /cygdrive/c/somedir
C:\somedir
Cygpath так-же успешно транслирует обращения к этой точке монтирования в Windows пути.
Кстати, существование такой утилиты как cygpath показывает, почему с cygwin вы, при возможности, должны пользоваться только ее утилитами. Если, вам нужно запустить java VM, а она понимает только Windows пути, вам придется cygwin путь преобразовать при запуске:
$ java -jar `cygpath -w '/opt/some.jar'`
Из этого следует, что многие скрипты из linux’а нельзя просто взять и запустить в windows. Нужно иногда постараться перенести скрипт. Более того, не все утилиты командной строки будут работать.

Больше возможностей

SSH

Вы можете поставить клиент и сервер OpenSSH — это позволит вам получить удаленный доступ к командной оболочке bash, с другого компьютера или, даже с телефона, например, с помощью JuiceSSH. Так-же вы получите удаленный доступ к своим файлам по протоколу SFTP(хотя на винде проще расшарить каталог, доступный по SMB).

Программирование

В комплект входят известные компиляторы, такие как Clang или GCC, интерпретаторы языков Python, Perl, PHP, Ruby и др. Вы можете собрать POSIX-совместимые программы под винду.

Текстовые редакторы

Интерактивные редакторы — vim, nano, emacs.
Не интерактивные редакторы, подходящие для использования в скриптах — sed, awk.

Итог

Если вы скучаете по возможностям linux в винде, возможно, стоит поставить эту штуку себе.
