KDE 终端没有颜色

我的 KDE Kubuntu 16.04.1 终端中没有颜色。

这里不起作用

这是我的.bashrc（我从 Ubuntu-Server 16.04.1 复制它，但我也总是在以前的 KUbuntu 12.04 上使用这个。）

我也尝试过这和这但我在终端和 ssh 上都没有颜色

> echo $TERM
xterm-color

apt update无论如何，或例如的彩色输出ls -a有效

la作品在一般作品中如此色彩

只是不是我希望在复制 .bashrc 的另一台服务器上看到的提示以及它正在工作的位置：

在这里它起作用了

我有什么遗漏的吗？如何让彩色提示正常工作？ （特别问，因为我想要我的绿色和根部的红色，但两者都不起作用）

答案1

我可能是错的，但我在您的脚本中没有看到任何与颜色相关的语法

PS1='${debian_chroot:+($debian_chroot)}\[\]\u\[\] @ \[\]\h\[\]:\[\]\w\[\]$ '

当我从 bash 提示符调用你的代码时

PS1='\[\]\u\[\] @ \[\]\h\[\]:\[\]\w\[\]$ '

我只看到白色字母。您甚至没有export PS1，这意味着该变量永远不会影响脚本之外的任何内容。我的猜测是，在您的旧机器上，其他一些脚本负责颜色。

为了获取您发布的颜色，请尝试从您的终端调用以下命令

PS1='\[\033[1;32m\]\u\[\033[0m\] @ \[\033[0;32m\]\h\[\033[0m\]:\[\033[31m\]\W\[\033[0m\]\$ '

如果有效，请将

export PS1='\[\033[1;32m\]\u\[\033[0m\] @ \[\033[0;32m\]\h\[\033[0m\]:\[\033[31m\]\W\[\033[0m\]\$ '

进入你的~/.bashrc.
