grep configure color display

Commands that must be used when checking logs. In order to facilitate display and viewing in the terminal, you can add color and highlight settings.

　　What I am used to: GREP_COLOR='a;b' a=4 means underline, b=41 means red background highlight

　　Add two lines to the ~/.bashrc file:　　

　　

export GREP_OPTIONS='--color=auto'
export GREP_COLOR='4;41'

Effective immediately, source ~/.bashrc
