How to delete lines matching a certain pattern in Perl?
I'd like to do something similar to sed in Perl, namely be able to delete lines matching a certain pattern.
Given this input:
abcd
edfd
abcd
derder
abcd
erre
I want to remove the lines containing bc. How can I do this?

I had to use double quotes on Windows:
perl -ne "print unless /bc/" file

This is a FAQ.
How do I change, delete, or insert a line in a file, or append to the beginning of a file?
If you're programming in Perl then it's well worth taking a couple of hours to familiarise yourself with the FAQ.
