    I have a set of files with file extension ovpn and wish to insert into each of them the following three lines:

    The above are to be placed after this line:

    The desired output should be:

    My attempt is:

    Code:
    sed -i -e '/auth SHA512/a\' \
        -e '\n\nscript-security 2\nup /etc/openvpn/update-resolve-conf\ndown /etc/openvpn/update-resolv-conf\n' \
        *.ovpn
    However the above commands add two blank lines after "auth SHA512" and a blank line after "down /etc/openvpn/update-resolv-conf".

    Can someone show me how to not add blank lines after "auth SHA512" and a blank line after "down /etc/openvpn/update-resolv-conf"?
