如何从 /bin/bash 行中删除路径？

如何从 /bin/bash 行中删除路径？

有没有办法隐藏 CLI 行中的路径？

现在我明白了：

fresh_m2@bloedlvm:/srv/www/vhosts/$

我想要这样的：

fresh_m2@bloedlvm$

因为如果我深入到文件夹中，那么光标已经在屏幕中间了：

fresh_m2@bloedlvm:/srv/www/vhosts/fresh_m2/vendor/magento/framework/Model/ActionValidator/RemoveAction$

路径已经显示在腻子的顶部，这对我来说就足够了：

在.bashrc您发布的内容中，删除标志\w前带有 PS1 的行$。根据您的需要，请务必在if [ "$color_prompt" = yes ]; then.如果您想在两者中删除它，可以使用以下命令：

前：

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi

后：

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h\$ '
fi

注意：更改仅在下一个会话中生效。

\w注意：我还从第一个 PS1 变量中删除了冒号和周围的颜色代码。

（看在 bash 人中，在标题“提示”下描述了转义序列）
