# Set "JeBrainsMono Nerd Font Mono" Regular font for the terminal
# e.g. for Terminator - must be run at least one time
sed -i '/\[\[default\]\]/,/^\[/s/^ *font = .*/ font = JetBrainsMono Nerd Font Mono 16/' "$HOME/.config/terminator/config"
Change the Zsh theme to use Powerlevel10k, add or update plugins to include additional Zsh plugins and add some lines before the source .*oh-my-zsh.sh command for additional configuration
ZSHRC="$HOME/.zshrc"
# Set the new theme
sed -i 's/^ZSH_THEME=.*/ZSH_THEME="powerlevel10k\/powerlevel10k"/' "$ZSHRC"
# Replace the plugins line with the new plugins
sed -i '/^plugins=/ { s/=.*/=(command-not-found kubectl zsh-autosuggestions zsh-syntax-highlighting)/; }' "$ZSHRC"
# Add additional lines before sourcing oh-my-zsh
sed -i '/^source .*oh-my-zsh.sh/ i \
# Fix errors\
ZSH_DISABLE_COMPFIX="true"\n\
\
# Skip all aliases in lib files\
zstyle '\'' :omz:lib:* '\'' aliases no\n' "$ZSHRC"
Check the file and restart zsh to apply the changes and configure Powerlevel10k Theme.
zsh
# Add "user" to be shown in the prompt
grep -q '^[[:space:]]*user[[:space:]]*$' "$HOME/.p10k.zsh" || sed -i '/os_icon.*# os identifier/ a\ user' "$HOME/.p10k.zsh"
EXTRA: to manually access the Powerlevel10k built-in configuration wizard again, run:
p10k configure

Set the same ohmyzsh config for the root user by symlinking the current user's zsh configuration.
Define custom Aliases within the ZSH_CUSTOM folder (if a oh-my-zsh user), or in the $HOME/.zshrc file if only zsh user.
