Can't delete with sed

Question

I have this text in /etc/bash.bashrc:

alias dwa='bash /opt/dwa.sh'

I tried to delete it with the following (and similar commands):

sed -i 'alias dwa=\'bash /opt/dwa.sh\'/d' /etc/bash.bashrc

Why did my sed operation fail?

You can't escape anything in single quotes. – n.caillou Dec 01 '17 at 20:28 — n.caillou, Dec 01 '17 at 20:28

Why search and replace when you can delete?

sed --in-place '/^alias dwa=/d' /path/to/file

That's not editing in place, and the {print $0} is wholly unnecessary – n.caillou Dec 01 '17 at 20:50
