I have a problem. I want to write an IP into a file with
sed -i 's/.*#source*/&\n'"$newsource"'/' file
This is because you must either escape your
/, or change the
sed separator to something else:
newsource=188.8.131.52\/24 sed -i 's/.*#source*/&\n'"$newsource"'/' file
newsource=184.108.40.206/24 sed -i 's~.*#source*~&\n'"$newsource"'~' file
Share and enjoy.
