How to use sed to delete all the chars from the last dot on?

How can I use sed to delete all the chars from the last dot on?

e.g.:

ns:base.cocktails.cocktail_garnish
ns:user.maport.cocktail.cocktail_recipe
ns:base.cocktails.cocktail_drinkware
ns:user.pjf.default_domain.chicken_breed
ns:user.radiusrs.default_domain.astrological_sign
ns:base.disaster2.type_of_tornado

I want to get:

ns:base.cocktails
ns:user.maport
ns:base.cocktails
ns:user.pjf.default_domain
ns:user.radiusrs.default_domain
ns:base.disaster2

This might work for you (GNU sed):

sed 's/\(.*\)\..*/\1/' file

Used greed to find the last . and delete thereafter.

You could use awk

awk 'BEGIN {OFS=FS="."} NF--' file

But sed is better for this job.

Using the sed regex:

awk '{sub(/\.[^.]*$/,"")}1' file

That's basic.

sed 's/\.[^.]*$//' file
