.bashrc break, second line entered in shell eats up first line
提问by sent-hil
I've using a .bashrc from one of peepcode's screencast.
我使用了来自 peepcode 的截屏视频之一的 .bashrc。

I can confirm the error is in grb_git_promit. What happens is the second lines typed in shell is overwriting the first line. Can anyone could help me with this?
我可以确认错误在 grb_git_promit 中。发生的情况是在 shell 中输入的第二行覆盖了第一行。任何人都可以帮我解决这个问题吗？
EDIT:
编辑：
PS1='\[3[38;5;1m\]some red text\[3[0m\]$ '
回答by Paused until further notice.
When you have colors and other non-printing escape sequences in your prompt, you have to surround them with escaped single brackets. Here is a simple example:
当您的提示中有颜色和其他非打印转义序列时，您必须用转义的单括号将它们括起来。这是一个简单的例子：
red='3[38;5;1m'
none='3[0m'
PS1='\[$red\]some red text\[$none\]$ '
Which will cause the prompt to display "some red text" in red and the dollar sign (or "#") in the default color.
这将导致提示以红色显示“一些红色文本”，并以默认颜色显示美元符号（或“#”）。
Here is another way to do the same thing:
这是做同样事情的另一种方法：
red=$(tput setaf 1)
none=$(tput sgr0)
By the way, to do this more portably and have less complex build-up of variables:
顺便说一句，为了更便携地做到这一点，并减少复杂的变量构建：
