How do i change bash-4.1# to user@hostname when login on linux PC Desktop Server

If you are facing above issue during login on Linux PC Desktop Servers so this may help to resolve the issue. What is Bash ? 

Bash is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. First released in 1989, it has been used as the default login shell for most Linux distributions. A version is also available for Windows 10 via the Windows Subsystem for Linux.

Problem occurs with login shellsIf the problem occurs with login shells as well as non-login shells, the problem is probably the same as above. If it occurs only with login shells, you either don’t have one of the files mentioned for login shells under the INVOCATION quote above, or they don’t source your ~/.bashrc, which is normal on most linux distros. If none of those files exists, create ~/.bash_profile with this in it:
if [ -f ~/.bashrc ]; then
  . ~/.bashrc
fi
This allows you, for the most part, to keep your configuration in one file (~/.bashrc).
If no matter what you do you cannot get a prompt back, you can create one and put it into ~/.bashrc this way:
if [ “$PS1 ]; then
    PS1= …. # see below
fi
This is because $PS1 is set and has a default value for interactive shells, and you don’t want to set it otherwise since other things may use this value to determine whether this is an interactive environment.
The bash man page contains a section PROMPTING which describes how to set a prompt with dynamic features such as your user name and current working directory, which would be, e.g.,:

To change bash-4.1# to user@hostname

Just go to /etc/skel 
run command $ls -a  it will show 
.bash_logout  .bash_profile  .bashrc  .kshrc 

Now cp bash_profile  .bashrc /home/usernametry to log out and login again you will notice normal bash prompt.
