Question

I want to remove following stream

 warning: the use of `mktemp' is dangerous, better use `mkstemp'

I tried using following sed expressions:

sed \
-e '/mktemp\' is dangerous/D' 

And

 sed \
    -e "/mktemp\' is dangerous/D"

But nothing works. What will be correct expression to remove that line from stream

baz
$ sed -e "/mktemp'/d" < /tmp/in.txt
foo

baz
