Question

I have 1000+ html files, all with more than 1000 lines, on a Linux server.
Most of the files have a particular part of html code that needs to be deleted.

The part that I need to deleted looks about this:

<div class="LoginOuterCssClass" id="ctl07">
    ...
</div>

Is there some script or command-line solution for this?

Commands like the following didn’t help:

X,Ys/search/replace/g
1,2s/\([a-z]*\), \([a-z]*\)/\2 \1/ig
s/<[^]*>//g

Help would me much appreciated!

Try the following sed command on one file and see if it does what you want:

sed -n '/<div class="LoginOuterCssClass" id="ctl07">/{:a;N;/<\/div>/!ba;N;s/.*\n//};p' file.html

To run this on multiple files and edit them in-place, you run find and pass the files to sed via xargs as shown below:

find /some/path -name "*.html" -print0 | xargs -0 sed -i -n '/<div class="LoginOuterCssClass" id="ctl07">/{:a;N;/<\/div>/!ba;N;s/.*\n//};p'
