Its possible to use awk in Alias command. I did that by simply just modifying some parenthesis and there you go, had a working awk command.
All that it required was closing awk in double quotes as opposed to single quotes and forward slash before the “$” variable. This alias command is for printing the default Gateway for an interface.
alias eth0-gw='route -n | grep eth0 | awk "NR==1{ print \$2 }"'
