I'm using sed (GNU sed) 4.4
sed '\@a@d' conf.js I can delete with a custom delimiter
sed '/a/,/b/d' conf.js I can delete an inclusive range with a pattern
sed '\@a@,@b@d' conf.js` `sed: -e expression #1, char 7: unexpected `,' But I cannot delete an inclusive range with a custom delimiter because it doesn't expect the comma
How can I delete lines between two patterns, while using a custom delimiter?
