How to return lines, where the last word ending with a consonant letter?

My regex should return lines, where the last word ending with a consonant letter. I write:

egrep '[^aeiou]\b$'

but it returns only lines, which not ending in a dot.

I'm a beginner in regex, so I will be grateful if you could help me.

For example, my test file:

Hello world
Hello world.
London is the capital of GB.
Oslo is the capital of Norway
Oslo is the capital of Norway.
Oslo is not a capital of Ukraine.

Now my expression returns:

Hello world
Oslo is the capital of Norway

But it should return:

Hello world
Hello world.
London is the capital of GB.
Oslo is the capital of Norway
Oslo is the capital of Norway.

The problem with your regex is that it looks for a letter that is not a vowel but in other side it doesn't necessarily looks for consonants. The \b shouldn't be there too. As You want to ignore punctuation marks try the following:

egrep '[b-df-hj-np-tv-z]\W*$'

\W means a character that is not [a-zA-Z0-9_]
