I want to use "sed" to insert newlines (one line turns into hundreds)

Question

I want the sed equivalent of this line of vim:

:s/","/",^M"/g

The goal: Take a line that contains a massive json block, and break it up into individual lines.

An example of what I want to work with is http://www.cartoonnetwork.com/video/teen-titans-go/episodes/index.html (look for function getFullEpisodes()).

What I tried:

519  sed -e 's/","/",\n"/g' < /tmp/url > /tmp/line-url

-- did not work, just put "n" at the proper place.

521  sed -e 's/","/",\\n"/g' < /tmp/url > /tmp/line-url

-- did not work, put a backslash followed by n at the proper place.

The full "script" of vim commands that I want to turn into a shell script:

:s/","/",^M"/g
:1,$!grep seo
:g,^.*/vid,s,,http://www.cartoonnetwork.com/vid
:g/"},{.*/s///
:$s,"}];,,
:wn

Answer 1

It seems your version of sed does not understand \n on the RHS of s///.

You could always do this on a bash command line:

sed -e 's/","/",\
"/g' < /tmp/url > /tmp/line-url

On a csh command line, you would need to double the backslashes. Note that the trailing backslashes should not be followed by anything other than a hard newline.
