unable to use new line in sed search pattern.
hi ,
my lilo.conf is as shown below :
Code:
prompt
    default=Primary
    read-only

image=/boot/bzImage
    label=Primary
    root=/dev/md0
    append="reboot=t md=0 ip=off panic=5 quiet console=ttyS0,115200n81"
    read-only

image=/boot/bzImage
    label=Recover
    root=/dev/sda3
    append="reboot=t ep=off panic=5 quiet console=ttyS0,115200n81"

image=/boot/bzImage
    label=SecRoot
    root=/dev/sda2
    append="reboot=t ip=off panic=5 quiet console=ttyS0,115200n81"

i am writing a tool which takes as input Primary/SecRoot/Recover, based on which i should replace the line "image=/boot/bzImage".

For example if i give SecRoot as input then

image=/boot/bzImage
label=SecRoot

should get replaced by

image=/secroot/boot/bzImage
label=SecRoot

I tried many options of sed, but could not correctly implement it. any help is greatly appreciated.

SYNOPSIS

       /usr/bin/cdvd [-b] file

DESCRIPTION

       The cdvd command reads the Primary Volume Descriptor from a CD-ROM and lists the contents on standard output.

       The output is formatted in a table that contains the name of each field of the Primary Volume Descriptor and the corresponding contents	of
       the entry as recorded on the CD-ROM. Note that the Application Use Field is not listed because it may contain non-printable characters.

       Users must have read permission for file in order to execute the command.

EXIT STATUS

       or not a block special file for a CD-ROM File System, or access permission was denied.  The named file is a block special file and  a  read
       error has occurred, or the CD-ROM is not recorded according to the ISO 9660 standard.
