When I start to enter in different folder the path is registered in my command line and I don't know how to remove it. I am almost sure my question wasn't clear. An example is always better. Once in home:

luiz@feynman:~$ cd Music/
luiz@feynman:~/Music$ cd Beatles/
luiz@feynman:~/Music/Beatles$ cd 17\ Love/

What is annoying me is this :~/Music or ~/Music/Beatles before $. It seems a stupid problem but when I need to enter into many folders is really a big problem. I guess I should change something in my .bashrc, but I don't know what.

Thanks

Off-topic. But Google for Bash PS1. –  Oli Charlesworth Apr 7 '12 at 15:38

look at and edit the value of $PS1. It contains the template for your prompt.

Something like '\u@\h \w $ ' is typical, in this the '\w' is a placeholder for the working directory. SettingPS1'\u@\h $ '` would remove the working directory.

For full details on how to set PS1, consult the bash man page

\W instead of \w will show only the directory you are in –  Rob Apr 8 '12 at 2:38

You can use this prompt for PS1

PS1='\u@\h: $(x=$(pwd); l=${#x}; if [ $l -lt 24 ]; then echo $x; else echo ... ${x: -20};fi;)\$'

Just put this at the very end of your .bashrc. From now every time you go to a path with a length greater than 24 it'll show the last 20 characters preceding by .... In fact when we go deep down a directory only the last directories become significant. Because we already know where we started.

thanks shiplu.mokadd.im, I've already done what @je4d. But I will try your elegant suggestion latter. –  ziulfer Apr 7 '12 at 16:04

Or you could use PROMPT_DIRTRIM to only include the last couple of directories in the prompt.
