Для комфортной работы в консоли требуется не так много – привычные алиасы, переменные окружения, настройки локали, настройки readline (файл ~/.inputrc), screen и т.д. И желательно, чтобы все эти настройки были одинаковые, независимо от того в какой консоли вы работаете прямо сейчас, в Ubuntu, CentOS, macOS или Synology.

Я для себя постарался унифицировать файлы с этими настройками, для того, чтобы можно было скопировать их в домашнюю папку на свежеустановленную систему и продолжить работать в привычном окружении.

Подготовка папок для конфигурационных файлов:

$ mkdir -p ~/.config/bashrc
$ mkdir -p ~/.config/bashrc.d

В папке ~/.config/bashrc будут находиться стандартные файлы из домашней папки (.inputrc, .screenrc, .bash_profile и .bash_logout). В самой домашней папке будут симлинки на эти файлы. А в папке ~/.config/bashrc.d – будут находиться различные конфигурационные файлы, которые будут считываться во время выполнения файла ~/.bash_profile автоматически.

Настройка readline:

$ nano -w ~/.config/bashrc/.inputrc
"\e[1;3C": forward-word
"\e[1;3D": backward-word
"\e[1;5C": forward-word
"\e[1;5D": backward-word
"\e[1~": beginning-of-line
"\e[4~": end-of-line
"\e[7~": beginning-of-line
"\e[8~": end-of-line
"\eOH": beginning-of-line
"\eOF": end-of-line
"\e[H": beginning-of-line
"\e[F": end-of-line
"\e[5~": history-search-backward
"\e[6~": history-search-forward
$ ln -s ~/.config/bashrc/.inputrc ~/.inputrc
