I have been done this a while ago, it's bad, but it works for me even with the problems that this script have.


#!/bin/sh

# BEGIN

fdisk=$(which fdisk)


case "$1" in
	scsi)

	$fdisk -l | grep dev | gawk -F' *' '{ print $1 }' | gawk -F'/dev/' '{ print $0 }' | grep '/dev/sd' > particiones.txt
	MSG="Se han detectado un total de $(cat particiones.txt | wc -l) particiones a escanear"
	echo $MSG del tipo $1

	for particion in $(cat particiones.txt)
	do
	detecta2=$($fdisk -l | grep $particion | grep + | gawk -F'+' '{ print $2}' | gawk -F' ' '{ print $2 }')
	detecta3=$($fdisk -l | grep $particion | grep + | gawk -F'+' '{ print $2}' | gawk -F' ' '{ print $1 }')
	echo "Detectando tipo de particion $1 para $particion:  $detecta2 con numero magico $detecta3"
	#rm -v particiones.txt 2&>1
	done
	;;
	ide)

	$fdisk -l | grep dev | gawk -F' *' '{ print $1 }' | gawk -F'/dev/' '{ print $0 }' | grep '/dev/hd' > particiones.txt
	MSG="Se han detectado un total de $(cat particiones.txt | wc -l) particiones a escanear"
	echo $MSG del tipo $1
	for particion in $(cat particiones.txt)
	do
	detecta2=$($fdisk -l | grep $particion | grep + | gawk -F'+' '{ print $2}' | gawk -F' ' '{ print $2 }')
	detecta3=$($fdisk -l | grep $particion | grep + | gawk -F'+' '{ print $2}' | gawk -F' ' '{ print $1 }')
	
	echo "Detectando tipo de particion $1 para $particion:  $detecta2 con numero magico $detecta3"
	#rm -v particiones.txt 2&>1
	done
	;;
	*)
	echo "Uso: $0 ide | scsi "
	exit 0
esac
