After switching to exa as an ls-replacement i also wanted to make use of the nerd-font support ho have icons displayed for files.

alias etree='exa --color --tree --icons=always'

However, in reality the fonts never looked the same in my terminal as in the web preview

So, to easy things up (getting the zip, unzipping it in ~/.local/share/fonts and updateing the fonts-cache) there is a little function which can be placed in the .zshrc/.bashrc to automate things.

#Function to install NerdFonts
function install_nerdfont()
{
	if [ -not $1 ];
	then	
		echo -e "\e[91mParameter missing!\e[0m"
	fi

	cd ~/.local/share/fonts
	wget $1
	unzip -u *.zip
	rm *.zip
	fc-cache -fv	
	cd -

}

Once executed with the download-URL as a paremeter, the font will be installed to your home directory.

If the fonts should be installed system-wide, this can be archived by placing them in /usr/local/share/fonts (folder might needs to be created if it does not exist).

Once the fonts are installed – the terminal-profile must be configured to use the newly installed fonts and that’s it.
