Delete a line in a file starting with - Perl one-liner

Hi

I need a perl onliner to delete a line in a file starting with few words.
Example

file.txt
----------
my name is don
I live in London
I am woking as engineer

I want to delete a line starting with 'I live in' using perl oneliner and in place edit with out temporary files

Thanks in advance
Ammu

perl -i -nle 'print if !/I live in/' file.txt

and how about:

perl -i -nle 'print if !/^I live in\b/' file.txt

but Franklin52's solution would work well in most situations
