Bash Prompt

(1/2) > >>

There is a shell variable PROMPT_COMMAND that is interfering with all of the normal means of setting the bash shell prompt. The following in your .bashrc should fix it.

Not quite sure of your question here. Are you saying you are running the "live" ISO or an installed system? You can certainly customize the prompt on any Linux/Unix system ... except for many "live" ISOs and "safe" mode mods.


I have the same problem, running LL 4.4, I cannot change the bash prompt in any terminal.  I've tracked it through all the normal config files and changed everything I thought might have an effect, to no avail.

One suspicious thing, the definition for PS1 when you echo it is fully expanded:

--- Code: --- thomasd  ~  echo $PS1
\[\] thomasd \[\] \[\]~ \[\] \[\]
 thomasd  ~  

--- End code ---

so it looks like some service somewhere is setting PS1 in the background.


Hello dave61430,

it can be changed on desktop installed LL 3.2 , LL 4 series uses different terminal, maybe a member using 4 series can try also ?

^Here I backup default prompt, echo backup to check it is correct, change prompt to PS1="\$ ", run cal to show new prompt holds after additional command, then restore to the backup of default prompt.
