Don't see LINUX or LVM in the output of fdisk -l. Maybe you are using other than GNU Linux?

What I see here...
Code:
NewDisk=`fdisk -l | grep Linux | egrep -v '\*|LVM' |awk '{print $1}' | sed 's/\/dev\///'`
echo $NewDisk
# -- produces --
# sda5 sda6 sda7 sda10 sda11 sda12 sdf2 sdf5 sdf6 sdf7 sdf8 sdf9 sdf10 sdf11

# (using sed -e to debug)
sed -e "s/^cdrom/harddrive --partition=$NewDisk --dir=\//"
# -- produces --
# error

In my case, $NewDisk appears to sed as a space separated list of commands, which are bogus...
The fix for me would be to make $NewDisk an array and access by [index]
Code:
NewDisk=(`fdisk -l | grep Linux | egrep -v '\*|LVM' |awk '{print $1}' | sed 's/\/dev\///'`)
sed -e "s/^cdrom/harddrive --partition=${NewDisk[0]} --dir=\//"

In your case, making $NewDisk=csicc/c0d0p5 like you reported, still throws an error because sed sees the /slash in csicc/c0d0p5 as a delimiter...
So change the delimiter in sed from / to |...(ala Scrutinizer post #2)

Code:
NewDisk=csicc/c0d0p5
sed -e "s|^cdrom|harddrive --partition=$NewDisk --dir=\/|"
-- produces --
harddrive --partition=csicc/c0d0p5 --dir=/

Give it a go and lemme know if I need to make any edits here.

Thx

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
