I am taking efforts to learn sed and encounter such a situation



$ echo "abcd" | sed -n "/b/p"
abcd


it works properly,



$ echo "abcd" | sed -n "
→ /b/p"
abcd


good again, but



$ echo "Abcd" | sed -n "/b
/p"
sed: -e expression #1, char 2: unterminated address regex


What's the problem with the error report?






bash sed
