customise your linux terminal prompt

This is how my final terminal should look like

nuwans:mediation-dep-gw (master) $



I have removed

• lengthy host name,
• very long directory structure
• and added git branch

This can be done via .bashrc file located in your local home directory. in bashrc file PS1 variables handles the terminal prompt.

parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
if [ "$color_prompt" = yes ]; then
    PS1='\[\033[01;32m\]\u:\[\033[01;34m\]\W\[\033[00m\]$(parse_git_branch) $ '
else
    PS1='\u:\W\$ '
fi

Paste above code to the bashrc file to update the existing code.

What I have done?

PS1='\[\033[01;32m\]\u:\[\033[01;34m\]\W\[\033[00m\]$(parse_git_branch) $ '

PS1 - sets the terminal pattern used by linux os.

\[\033[01;32m\] - setting the colour

\u - user name
\W - current folder
$(parse_git_branch) - will read git branch  info and if its not git folder empty value is retured.
