Hi danmero,

Unfortunately I get the same error:

[root@performance ~]# sed -i 's/$/\ console=ttyS0,115200/' grub.conf
[root@performance ~]# echo $?
0
[root@performance ~]# export cmnd="sed -i 's/$/\ console=ttyS0,115200/' grub.conf"
[root@performance ~]# $cmnd
sed: -e expression #1, char 1: unknown command: `''

There is a problem when the sed command is stored in the env variable and then called. This is strange because it works with every other command I tried.

NAME
grub-install - install GRUB on your drive SYNOPSIS
grub-install [OPTION] install_device DESCRIPTION
Install GRUB on your drive. -h, --help print this message and exit -v, --version print the version information and exit --root-directory=DIR install GRUB images under the directory DIR instead of the root directory --grub-shell=FILE use FILE as the grub shell --no-floppy do not probe any floppy drive --force-lba force GRUB to use LBA mode even for a buggy BIOS --recheck probe a device map even if it already exists INSTALL_DEVICE can be a GRUB device name or a system device filename. grub-install copies GRUB images into the DIR/boot directory specfied by --root-directory, and uses the grub shell to install grub into the boot sector. The grub source distribution carries this script to ease the installation of grub as a boot loader. In Suse Linux however, grub installa- tion is much better handled by Yast; use of this script is generally discouraged and therefore unsupported. Consequently, the script has been renamed to grub-install.unsupported. In order to (re-)install grub for the currently running system, simply use Yast. For an installation aiming at a differing system, the crafting of an appropriate device.map and grub shell script is strongly advised, e.g. "grub --batch --device-map=target-device.map < tar- get-grub.conf" SEE ALSO
The full documentation for grub-install is maintained as a Texinfo manual. If the info and grub-install programs are properly installed at your site, the command info grub-install should give you access to the complete manual. grub-install (GNU GRUB 0.97) May 2005 GRUB-INSTALL(8)
