help please: apply REGEX to multiple lines?
hi friends! happy new year!
i never manage to do a regex includeing multiple lines, does anyone has an idea about that?
imagin you have a file
and you want to turn it into just
but without useing grep next line/line before
it needs to be something like:
sed -i "s#a\n(b\n)c\n#$1#g" file (which does not work)
thanks a lot
