Question

How can I change prompt name seen at terminal ?

my prompt :

<user_name>@<user_name>-MEGA-BOOK-VR320:~$

It is too long. I want to change it as :

gcc : 

However, I should see path when I have go from one directory to another.

gcc :~$ cd X_directory
gcc :~/X_directory$

How can I do that, permanently ?

Answer 1

Test it with this:

export PS1="gcc :\w\$ "

If if its what you want, then change it in your .bashrc file:

gksu gedit .bashrc

delete or comment out this line:

PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '

and replace with

PS1='gcc :\w\$ '

• note if your username is "gcc" then you could replace gcc with \u

Hope that helps. More info on PS1 here.

Answer 2

1. First, open a terminal and type:

   root@penreturns:~$ gksu gedit /etc/hostname

You should see a line stating your current hostname. For eg. iPad

1. Change the hostname to something you desired. Save and close the file.

2. Back in your terminal, type:

   root@penreturns:~$ gksu gedit /etc/hosts

3. Change the line:

127.0.1.1 iPad

to

127.0.1.1 your-new-hostname

Save and close the file.

Reboot and your new hostname should appear in the terminal now.

*copy code without root@penreturns:~$
