I need to insert text to a file with quotes using sed

Hi Stackoverflow users,

Normally I can use sed pretty wel (often need a few tries). However I am having issues with adding the text below at the end of the file:

<linebreak/empty line here>
[extensions]
blacklist = "google-authenticator"

Into a file called: /usr/local/psa/admin/conf/panel.ini

To make things "more" complicated, I also use the command in OpenVZ automation. Like this:

vzctl exec $VEID 'sed XX "VALUE FROM ABOVE" /usr/local/psa/admin/conf/panel.ini'

Can someone provide some help and/or direct me in the right direction?

Obviously I tried a few things, but I think I am having issues with the extra quotes in the text I am trying to add.

Errors are always something like this:

So I am doing something wrong and I have no clue how to correctly add the above. Preferably with a line-break in front.

I hope I explained the issue correctly. Thanks in advance for your assistance.

//Edit

All I need is a solution to add the following text:

<linebreak/empty line here>
[extensions]
blacklist = "google-authenticator"

by using sed.

So I can apply it to my script which creates an OpenVZ container (automated) like: vzctl exec $VEID 'possible sed solution here' /file-name

Sorry if I wasn't clear before.

Try using this GNU sed:

'sed -i '\''$a \\n[extensions]\nblacklist = "google-authenticator"'\'' /usr/local/psa/admin/conf/panel.ini'
  • -i: edit files in place
  • $: address matching the last line
  • a text: append text after a line

Just like @Kent recommended in his deleted answer, it would be more readable and simpler to save the text you want to append into a file and use the r file command to sed.
