Console prompt in bash changed unexpectedly

Question

In bash, my default console prompt looked like this:

kit:~ Kit$

I do not know what I did to make it change to this:

112:~ Kit$

What caused the 112: to appear? I'm in a different network, where my computer has an IP address that begins with 112.. Is it because of that? Or something else?

Answer 1

The bash prompt is governed by the PS1 variable and it's hard to say what's going on without knowing what the variable is set to.

echo "$PS1" will show you its current value.

For more information type man bash and look under PROMPTING section.

Answer 2

I don't know why it changed, but why not change it back? - look at this

Answer 3

A simple solution is to change it back to the way it was. To change it back, add the following to your ~/.bashrc:

PS1='\w \u\$ '
