How to use

One-Time

1. You can just paste the whole function into your shell and enter,
2. and just run colorgrid

Save

1. Save to where you prefer (like ~/.colorgrid),

2. append to your shell init file like ~/.bash_aliases:

   if [ -f ~/.colorgrid ]; then
       . ~/.colorgrid
   fi

3. and then source the file and run

You don't have to append on every shell you use, if you source the same alias file (like ~/.bash_aliases being sourced by ~/.bashrc by default) on each shell init file.

For example, I appended ~/.bash_aliases on ~/.zsh_aliases so that I can use same aliases and user-defined functions in both terminal.
