What if the Linux (Ubuntu) terminal command Prompt is too long?

Due to the frequent use of the end (Zhuang) side (BI), each opening is the sauce of the drop:

or after entering a few levels of directory, it becomes Jiangzi:

True XX ugly! And just lose a few orders. What do we do? Very simple, in two steps:
