Bash Prompt
The prompt is the text Bash shows when it waits for your next command, often ending with $.
The prompt is stored in the variable PS1. When a command is not finished, for example a quote that is not closed, Bash shows the second prompt PS2, which is > by default.
Change the prompt
The new prompt shows up on the next line, and lasts until you close the terminal:
PS1="my-prompt> "
See the continuation prompt
echo "$PS2"
