How to sed remove last character from each line

Posted: 27 Apr 2020 12:08 PM PDT

I need to remove the last character from a line and shell variable such as "${_allowed_ips}". For example, each line is as follows in my file:
foo,
bar,
demo,
I need output as follows:
foo
bar
demo.
How can I use sed to delete the last character?
