sed: delete using a different delimiter

I can substitute line in file like this

sed "s|$PATH_WITH_SLASH||" file

but I cannot delete it

sed "|$PATH_WITH_SLASH|d"  file

The problem is that | character cannot be used for deletion. Why?

Answer 1

If you use other character as address delimiter, you need to use backslash before the first char. So

/address/

or

\|address|
