Very well done, reminded me of some code that I wrote (poorly, I might add)
but, I dug it up and found some changes that you might be able to implement
instead of lines and lines of static configs. That being said, take some
of these changes into consideration.
Dynamic detection of drives and partitions:
# Get Existing Drives
existing_drives=$(fdisk -l | grep /dev | grep -i disk | cut -c11-13)
# Set default drive
default_drive=$(fdisk -l | grep --max-count=1 /dev | cut -c11-13)
echo -e "What drive do you want to partition? [$existing_drives]: \c"
read drive
and then creating the partition table later:
# Make Drive Selection
if [ "$drive" == "" ]
then
selected_drive=$default_drive
else
# Verify Drive Exists
does_exist=$(fdisk -l | grep --max-count=1 -ci $drive)
if [ "$does_exist" == "1" ]
then
selected_drive=$drive
else
echo -e "The selected drive" $drive "does not exist. Using"
$default_drive "instead."
selected_drive=$default_drive
fi
fi
num_partitions=$(fdisk -l | grep ^/dev | grep -ic $selected_drive)
echo "There are" $num_partitions "partitions on" $selected_drive
partitions=1
# Clear existing partition file
rm -rf partition_table
touch partition_table
while [ "$partitions" -le "$num_partitions" ]
do
# Find partition numbers
edit_partitions=$(fdisk -l | grep ^/dev/$selected_drive | cut -c9)
# Parse out extra partitons
if [ "$partitions" == "1" ]
then
work_partition=$(echo -e $edit_partitions | cut -c$partitions)
# Write to partition_table file
echo -e "d\n$work_partition" >> partition_table
else
if [ "$partitions_cut" == "" ]
then
# If First Partition after partition 1, cut off
$partitions + 1
partitions_cut=$(($partitions+1))
else
partitions_cut=$(($partitions_cut+1))
fi
work_partition=$(echo -e $edit_partitions | cut
-c$partitions_cut)
# Write to partition_table file
echo -e "d\n$work_partition" >> partition_table
((partitions_cut += 1))
fi
((partitions += 1))
done
# build the rest of the table
# Get Total System Memory
total_mem=$(cat /proc/meminfo | grep -i memtotal | cut -c16- | sed s/\
// | sed s/kB//)
swap_space=$(expr $(expr $total_mem + $total_mem) / 1024)
# Write first partition to file
echo -e "n\np\n1\n\n+100M\n" >> partition_table
# Write Swap Space (double system memory)
echo -e "n\np\n2\n\n+"$swap_space"M\n">> partition_table
# Write / partition to file
echo -e "n\np\n3\n\n\n" >> partition_table
# Write partition setting to file and drive write
echo -e "a\n1\nt\n2\n82\nw\n" >> partition_table
# Set drive number variables
boot_drive=$(echo $selected_drive"1")
swap_drive=$(echo $selected_drive"2")
root_drive=$(echo $selected_drive"3")
# KEEP THIS COMMENTED OUT BELLOW HERE
fdisk /dev/$selected_drive < partition_table
Mainly due to the fact that you statically set the UUIDs of the drive that
you want to use.
Cheers,
Kad
