Regex: Remove lines containing "help", etc

This is also possible with Notepad++:

• Go to the search menu, Ctrl + F, and open the Mark tab.

• Check Bookmark line (if there is no Mark tab update to the current version).

• Enter your search term and click Mark All

  • All lines containing the search term are bookmarked.

• Now go to the menu Search → Bookmark → Remove Bookmarked lines

• Done.

Another way to do this in Notepad++ is all in the Find/Replace dialog and with regex:

• Ctrl + h to bring up the find replace dialog.

• In the Find what: text box include your regex: .*help.*\r?\n (where the \r is optional in case the file doesn't have Windows line endings).

• Leave the Replace with: text box empty.

• Make sure the Regular expression radio button in the Search Mode area is selected. Then click Replace All and voila! All lines containing your search term help have been removed.
