Let's start with what the hell is bash prompt. It's simple, whenever you're in your bash terminal, you see your username and hostname before the input field:

We can change it however we want, using bash color formatting and bash prompt variables

Custom prompt should be specified in the bottom line of your user .bashrc file, which is located in your home folder:

nano ~/.bashrc

Here's example of prompt I'm using on my servers:

PS1="\e[35m[ \H\[\033[01;34m\] ] \t \w #\e[0m "

.bashrc file with custom prompt variable: PS1

# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
	. /etc/bashrc
fi

#My custom bash prompt
PS="\e[35m\H\[\033[01;34m\] \t \w #\e[0m "

Then we update our bash prompt by typing:

source ~/.bashrc
