Different distros are preconfigured for different user populations. On a desktop, you mainly just expect to see a simple prompt and maybe the current directory; for a server distro, it is useful for the prompt on each server to be different from every other server, so that you can tell at a glance where you are logged into (the admin typically logs into more than one server at the same time). Other than that, though, it's just a matter of taste, typically the taste of the Bash maintainer for your distro. Out of the box, the default prompt in Bash is just bash$ (where the dollar sign is replaced with a hash sign when you are logged in as root).

这是一个品味问题：每个人都可以使用环境变量 PS1 配置他的 PROMPT 行。
例如：
给出
，而目录是您的主目录的“~”。
It's a question of taste: everyone can configure his PROMPT-line with the env-variable PS1.
For example:
gives
whereas directory is '~' for your home-dir.
看起来是这样的：
即使颜色很好。为什么？因为我的
~/.bashrc包含 WithPS1行，所以您可以完全控制提示符的外观。您可以通过
man bash的PROMPTING部分获取更多信息。Here it looks this way:
even with nice colors. Why? Because my
~/.bashrccontains the lineWith
PS1, you have full control over how your prompt looks like. You get more info withman bash, sectionPROMPTING.不同的发行版是针对不同的用户群体预先配置的。在桌面上，您主要只是期望看到一个简单的提示，也许还有当前目录；对于服务器发行版，每台服务器上的提示与其他服务器上的提示不同是很有用的，这样您一眼就能看出您登录的位置（管理员通常会同时登录多个服务器） 。但除此之外，这只是一个品味问题，通常是你的发行版的 Bash 维护者的品味。 Bash 中的默认提示符就是
bash$（当您以 root 身份登录时，美元符号将替换为井号）。Different distros are preconfigured for different user populations.
