Bash 换行和历史滚动
我的 bash 提示符和换行行为遇到问题。如果我使用静态提示符,
export PS1="test$ "; ### Works perfectly
我可以在提示符上键入长行,并且它们可以很好地换行。在历史记录中向上/向下滚动也可以正常工作。 在使用动态提示时,例如:
export PS1="\u@\h(\W)$ "; ### Long lines don't wrap at all
长线变得混乱。找到了使长行正确换行的修复程序。 (http://hintsforums.macworld.com/showthread.php?t=17068)。
export PS1="\[\u@\h(\W)$ \]"; ### Long lines wrap while typing, but not while scrolling up/down through previous commands
但是,当向上/向下浏览提示历史记录时,行不会换行。我不知道如何用语言解释这种行为,但我会尝试 - 当我向上(向上箭头键)时,最后一个命令的一半被吃掉,光标最终位于换行符之间的某个位置。
对此有什么解决办法吗?
我记得在许多 Linux 发行版上,动态提示可以开箱即用地正常工作(这是在我的工作场所)。
问候,

I am having trouble with my bash prompt and line wrapping behaviour. If I use a static prompt
export PS1="test$ "; ### Works perfectly
I can type long lines on the prompt and they wrap fine. Scroll up/down in history also work fine.
On using dynamic prompt like:
export PS1="\u@\h(\W)$ "; ### Long lines don't wrap at all
long lines got scrambled. Found a fix that made long lines wrap correctly. (http://hintsforums.macworld.com/showthread.php?t=17068).
export PS1="\[\u@\h(\W)$ \]"; ### Long lines wrap while typing, but not while scrolling up/down through previous commands
However, when going up/down the prompt history, the lines do not wrap. I dont know how to explain the behaviour in words, but I will try - when I go up (up arrow key), half the last command is eaten up and cursor ends up somewhere in between where the line would have wrapped.
What is the solution for this?
I remember that on many linux distributions dynamic prompts work correctly out of the box (this is at my workplace).

此问题可能与提示本身无关,而更可能与终端仿真器的正常行为有关。
我使用这个 bash 提示符:
它实际上跨两行显示,看起来完全像这样:
使用 CTRL-N、CTRL-P 或箭头键,它与历史滚动完美配合。
我在 Terminal.app(在 MacBookPro 上)中使用 xterm-color。
This issue is probably not about the prompt itself, but more likely about the terminal emulator behaving properly.
I use this bash prompt:
which actually displays across two lines, looking exactly like this:
and it works perfectly fine with history scrolling, using either CTRL-N, CTRL-P, or the arrow keys.
I am using xterm-color in Terminal.app (on a MacBookPro).
