edit zsh prompt

1. append to .zshrc in home folder to import file:

   $ vim ~/.zshrc
   ...
   source .zshrc-prompt

2. create .zshrc-prompt in home dir:
   [code language="bash" collapse="true" title="~/.zshrc-prompt"]
   $ cat .zshrc-prompt
   # Prompt format: [USER@MACHINE:DIRECTORY] [TIME] \n →;

   # create bold fonting+color
   PROMPT="%{$terminfo[bold]$fg[green]%}[%{$fg[yellow]%}"

   # username@MACHINE:
   # %n username
   # %M machine
   PROMPT="$PROMPT%n@%M:"

   # directory
   # %~ directory and $HOME is repalced by ~
   PROMPT="$PROMPT$fg[blue]%}%~"

   # color stuff
   PROMPT="$PROMPT%{$fg[green]%}]%{$reset_color%}"

   # add time
   PROMPT="$PROMPT%{$terminfo[bold]$fg[black]%} [%*]"

   # add 2nd line
   PROMPT="$PROMPT
   %{$terminfo[bold]$fg[white]%}→ %{$reset_color%}"
   [/code]

3. do same for root (same as (1)):

   $ vim /root/.zshrc
   ...
   source .zshrc-prompt

4. similar to (2):
   [code language="bash" collapse="true" title="/root/.zshrc-prompt" highlight="2,5,24"]
   $ cat /root/.zshrc-prompt
   # Prompt format: [USER@MACHINE:DIRECTORY] [TIME] \n #;

   # create bold fonting+color
   PROMPT="%{$terminfo[bold]$fg[green]%}[%{$fg[red]%}"

   # username@MACHINE:
   # %n username
   # %M machine
   PROMPT="$PROMPT%n@%M:"

   # directory
   # %~ directory and $HOME is repalced by ~
   PROMPT="$PROMPT$fg[blue]%}%~"

   # color stuff
   PROMPT="$PROMPT%{$fg[green]%}]%{$reset_color%}"

   # add time
   PROMPT="$PROMPT%{$terminfo[bold]$fg[black]%} [%*]"

   # add 2nd line
   PROMPT="$PROMPT
   %{$terminfo[bold]$fg[red]%}# %{$reset_color%}"
   [/code]
