How the teminal shell HostName can be as “229:~ lancee$” ?

This topic created in 5575 days ago, the information mentioned may be changed or developed.

登入MB终端的时候本应是：
"Last login: Tue Mar 1 17:19:48 on ttys000
ly-lanceedemacbook:~ lancee$ "

有的时候却是：
"229:~ lancee$"
是什么意思呢？

谢谢解答。

It prints :

"Last login: Tue Mar 1 17:19:48 on ttys000 ly-lanceedemacbook:~ lancee$ "
when I login terminal on my Macbook with networking.

But sometime go like this :

"229:~ lancee$"
random numbers, Is there any hackTools working within the local area network? or means what?

如 stackoverflow 那位仁兄所说的，执行 echo "$PS1" 的结果是什么？这个 grep 'PS1' ~/.profile ~/.bashrc /etc/profile 呢？

@TheOnly92 谢谢:D

echo "$PS1"
\h:\W \u\$

ly-lanceedemacbook:~ lancee$ grep "\h:\W \u\$" ~/.profile
ly-lanceedemacbook:~ lancee$ grep "\h:\W \u\$" ~/.bashrc
grep: /Users/lancee/.bashrc: No such file or directory
ly-lanceedemacbook:~ lancee$ grep "\h:\W \u\$" /etc/profile

shell只知皮毛，学。:P

这个可以修改的, 修改你的 shell 配置文件, 比如我的是这样的 http://readful.com/post/2810013340/oh-my-zsh-zsh-theme

@roamlog thx, 就是说可以改掉 prefix 了？

那么你的 PS1 就得修改成 \u \W \$ 或者是你喜欢的类型。你可以在 shell 不断执行 PS1="\u \W \$" 诸如此类，然后感到满意后在 home folder 创建一个叫 .bashrc 的文件，然好将 export PS1="..." 存起来就行了。

有可能是网络的DHCP服务器改的HOST
