I know, but I wanted it to be a 'one line command' w/o additional script
files; yesterday evening, while sitting in a beergarden, I came up with
the idea to first add one line to the file after the line with pattern1 and
use this new pattern3 for the start of the deletion:
awk -v D=pattern3 '{ print } ; /pattern1/ { print D }' | sed '/pattern3/,/pattern2/d'
Thanks for your thoughts in any case
