I'm new to Ubuntu 14.10, and I want to change the 'your name' (appear at the time of Installation) from hanu to Hanu in Terminal, i.e., hanu@4268 to Hanu@4268.

    I think OP wants to change his username not the hostname. – Arronical Apr 13 '15 at 14:35

    None of the two, he wants to change how its username *it's displayed* within the terminal, not to change his *actual* host name or his *actual* username. – kos Apr 13 '15 at 14:57

You can accomplish this using a case modification parameter expansion of $USER instead of \u inside the PS1 environment variable. The expansion would be ${USER^} to uppercase only the first letter of the username).

You can run this variable assignment on the terminal to see the effect:

PS1='\[\e]0;${USER^}@\h: \w\a\]${debian_chroot:+($debian_chroot)}${USER^}@\h:\w\$ '

If do you want to make this change permanent, you can use this method:

  1. Edit the .bashrc file in your home folder

  2. Locate these lines:

    if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi

  3. In the two lines that begin with PS1=, replace \u by ${USER^}, so it looks like this:

    if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]${USER^}@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}${USER^}@\h:\w\$ '
fi
