You can almost accomplish this entire task using awk. For example:
awk -F '$' '/shrimp/ {printf "%s- %.2f\n", $1, $NF}' < menu.txt
awk is Turing Complete. s/almost//
With real life menus with millions of lines, you usually start with head | grep, and then, when you one-liner of 15 lines is complete, you replace head with cat and cross your fingers
head | grep
real life menus with millions each? ;)
That was my attempt to make a joke
Grep won't be able to find anything because you are searching for ! Which is not in the menu
