I found that in my cygwin,
The PS1 console have 2 lines and I want to solve it. This is due to "\n" at the end of PS1
But I cannot export it well due to "not a valid identifier" error.
How can I solve this? Many thanks.
When you say export, you don't use the dollar sign.
So it's export PS1=Hello World, not export $PS1=Hello World.
export PS1=Hello World
export $PS1=Hello World
