notepadregextext editing
I have the following text in Notepad++.
192.168.0.1 37 ms N/A
192.168.0.2 Dead N/S
192.168.0.3 Dead N/S
192.168.0.100 37 ms N/A
How do I do a find and replace that matches "Dead" and eliminates the line with output like the following?
192.168.0.1 37 ms N/A
192.168.0.100 37 ms N/A
I have tried to use the regular expression ^.*Dead.*$ that does remove the lines, but it doesn't delete the empty spaces.
You can achieve this by using Backreferences and Find and Mark functionality in Notepad++.
Find the matches using regex (say %(.*?)% ) and replace it by \n%\1%\n , after this we will have our target word in separate lines (i.e. no line will have more than one matched word)
Use the Search-->Find-->Mark functionality to mark each line with regex %(.*?)% and remember to tick 'Bookmark Line' before marking the text
All you need to do is check . matches newline in Notepad++ Search/Replace Search Mode:
This will make the dot . in your regex match newline, so .* will match any number of newlines.

Go to the search then to the Mark tab, enter "Dead", check "mark line" and click "Find all". It results in bookmarks for all those lines.
In the search menu there is a point "delete bookmarked lines"
