printf 'Hello\n' | sed '
s/foobar//
t end
s/Hello/Goodbye/
:end'
This works as expected, it prints Goodbye.
printf 'Hello\n' | sed '
s/Hello/Hello to you/
s/foobar//
t end
s/Hello/Goodbye/
:end'
Since t should only look at whether the *last* substitution changed the pattern
space, it is my understanding that this should print:
Goodbye to you
But sed prints instead:
Hello to you
If I got this right, that means there's a bug in sed – maybe resetting the
"last substitution was successful" flag isn't done properly? Or am I
misunderstanding something here after all?
Tried on these versions, both did exactly the same:
$ sed --version | head -n1
sed (GNU sed) 4.2.2
sed (GNU sed) 4.5
