Ubuntu Personalized Environment Configuration

If after the installation of Ubuntu, but found that the terminal prompt after the name is too long or uncomfortable, such as [email protected], this name is not pleasant, want to change how to do?

1, need to modify two files: Vim/etc/hosts the name of the inside to Ubuntu;
Vim/etc/hostsname changed the name of the inside to Ubuntu.
Restart Ubuntu and open the terminal again to see that the changes were successful and changed to [email protected]:

2, now, I want to [email protected] This prompt shiny, need to modify the Vim ~/.BASHRC, the inside of the force_color_prompt=yes in front of the note ' # ' removed

Turn the terminal back on and you'll see the prompt glow.

2.1 Here also describes how to modify the color of the cue symbol

On the command line, enter:gedit ~/.BASHRC

Find the content below

# should is on the output of commands, not on the Promptforce_color_prompt=yesif [-n "$force _color_prompt"]; Then    if [-x/usr/bin/tput] && tput setaf 1 >&/dev/null; then# We had color support; assume it ' s comp Liant with ecma-48# (iso/iec-6429). (Lack of such support are extremely rare, and such# a case would tend to support setf rather than SETAF.) Color_prompt=yes    elsecolor_prompt=    fifiif ["$color _prompt" = yes]; then    ps1= ' ${debian_chroot:+ ($debian _chroot)}\[\033[01;31m\]\[email protected]\[\033[00;33m\]\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' Else    ps1= ' ${debian_chroot:+ ($debian _chroot)}\[email protected]\h:\w\$ ' Fiunset color_prompt force_color_prompt

The following changes are displayed:

@ Front is red, yellow after @: white; ~ Blue; ￥ white, command line character is white

Ps1= ' ${debian_chroot:+ ($debian _chroot)}\[\033[01;31m\]\[email protected]\[\033[00;33m\]\h \[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

The above statement is my modified, according to the color corresponding

[01;31m\] corresponding parameter, semicolon interval, M end
