OpenWRT Command Line Prompt via SSH
...at least it isn't as bad as the default Command Line Prompt from Redhat / CentOS. It has the most important thing, even Microsoft has included with DOS: The current FULL path (not just a directory) where one is in the file system. For example: root@WRT3200ACM:/etc/config
How does one modify it? Change the PS1 variable (the line that starts off: export PS1='WhatEverStuff ' ), it's in /etc/bashrc. But for OpenWRT it's in /etc/profile.
The default value for PS1 = PS1='\u@\h:\w\$ ' (\u = User Name, \h = Host Name, \w = Full Path, \$ = # if one is logged on as the root user, $ for any other user)
This results in (for example): root@WRT3200ACM:/etc/config
What if you want just the path? Use this: PS1='[\w]\\$ '
For an 'old fashion' DOS prompt: export PS1='\h:\w > '
If you're logged on via IP / SSH, disconnect and reconnect to a new session for settings to take place.
If you're connected via Serial / TTL, type exit, then press enter a couple of times to start a new session.
If one is working on several OpenWRT routers, it will probably be useful to leave in the \u (Host Name)
CentOS uses Double Quotes ( " ) around what the PS1 variable is set to. OpenWRT uses Single Quotes ( ' ). Since both are really BASH based, probably both would work for OpenWRT. But if one wants to stick with the convention, use Single Quotes.
