定制 linux 提示符

定制 linux 提示符

在 bash 中提示符是通过一个环境变量$PS1 指定的。
用 export $PS1 查看现在的值，比较直观常用的提示符可以设定为 export PS1=“[\u@\h \W]\$”。
其中\u 代表用户名，\h 代表主机 名，\W 代表当前工作目录的最后一层，
如果是普通用户\$则显示$，root 用户显示#

  4. Я именую этот препарат "оружием" выходного дня. Я имею отменное здоровье. Но с возрастом стал ощущать убыток сил в интимных делах. Веду энергичный образ жизни, чувствую себя прекрасно. Безумно люблю секс. А здесь такой провал… Возникла неуверенность, даже унизительный страх. Необыкновенно трудно понять, что проще было: принять личную слабость или купить виагру впервые.

    Все дело в личном взгляде на себя. Почему общество не удивляет, что к определенному рубежу возникают сложности с давлением, суставами и т.д.? А употребить препарат для увеличения сексуальной силы вроде как неловко или не принято. Как поступать с всеобщим мнением, шаблонами? Я смог разобраться во всем этом. Осознал, что легче выпить чудную таблетку за час до интима, чем воспринимать себя неполноценным.

    Да, мне немного за пятьдесят. При этом веду более чем активный образ жизни во всех сферах. Купить виагру в Москве с доставкой, оказывается, сегодня еще проще, чем сходить в аптеку. На сайте предложен большой ассортимент различных медикаментов известной направленности. Но я остановился именно на этом популярном лекарстве. Один раз принял, помогло, понравилась. Нет нужды пробовать что-то еще. К тому же в нем охвачены все самые популярные свойства. Именно виагра увеличивает продолжительность секса, повышает качество секса, провоцирует возникновение эрекции.

    Рекомендую всем, кто столкнулся с похожей проблемой – не циклиться на личных провалах. А легко следовать вперед – навстречу новым результатам.
