How to copy contents of a text file into another file at a specific location

Hi everyone,

I have thousands of html files and I need to put a google plus button in each file. I don't feel like editing thousands of files manually so I want to do it with a linux command but can't figure out how to do it.

I have the following text in a file called googleplus.txt


<div class="g-plusone" data-annotation="inline" data-width="300"></div>
<script type="text/javascript">
(function() {
var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true;
po.src = 'https://apis.google.com/js/plusone.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s);
})();
</script>


I want to be able to place this block of text (above), which is in the file googleplus.txt into each of the thousand files just after a line called:



So once the job is done, each file should end up like this:



<div class="g-plusone" data-annotation="inline" data-width="300"></div>
<script type="text/javascript">
(function() {
var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true;
po.src = 'https://apis.google.com/js/plusone.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s);
})();
</script>


How can I do this to all html files in a diectory?
Any help would be greatly appreciated.
Thanks
Andy

Hi,
is there something else under  ? Or it is the end of file of your html files?

I would use sed, invoked by find

but mine is messy

Code:

find /path/to/inputDir -type f -name "*html" \
-exec sed -i.bak '/<!-- AddThis Button END -->/ a <!-- Google Plus Button START -->\
<div class="g-plusone" data-annotation="inline" data-width="300"></div>\
<script type="text/javascript">\
(function() {\
var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true;\
po.src = 'https://apis.google.com/js/plusone.js';\
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s);\
})();\
</script>\
<!-- Google Plus Button END -->' {} ';'

edit, I added .bak to -i ( so you get a back up )

solution with awk

Code:

for input in $(find /path/to/inputDir -type f -name "*html" );do
     tempOutput="${input}.temp"
     awk '/<!-- AddThis Button END -->/{print;system("cat /path/to/googleplus.txt")};!/<!-- AddThis Button END -->/{print}' "$input" > "$tempOutput"
     cp "$input" "${input}.bak"
     mv "${tempOutput}" "${input}"
done
