automount and umount script

Posted 08-16-2012 at 12:30 PM by ted_chou12

This is a sciprt that automounts and unmounts usb devices, because I realized my system does not consistently automount drives, and sometimes gets mounted incorreclty:
Code:
#mounts start with f
tbmounted=(f g h i j k l m n o p q r s t u v w x y z)

for each in "/dev/sd"* ; do
	mname=${each##*/}
	
	for alphabet in ${tbmounted[@]} ; do
		if [ "$mname" == "sd$alphabet" ] ; then
				mounts=$(mount | grep "$mname")
				if [ -z "$mounts" ] ; then
					i=1
					if [ ! -e "/dev/sd$alphabet$i" ] ; then
						if [ ! -d "/mnt/sd$alphabet" ] ; then
							mkdir "/mnt/sd$alphabet"
						fi
						mount "/dev/sd$alphabet" "/mnt/sd$alphabet"
					else
						while (( $i < 10 )) ; do
							if [ ! -e "/dev/sd$alphabet$i" ] ; then
							if [ ! -d "/mnt/sd$alphabet" ] ; then
								mkdir "/mnt/sd$alphabet"
							fi
							mount "/dev/sd$alphabet$((i-1))" "/mnt/sd$alphabet" ; break
							fi
							i=$((i+1))
						done
					fi
					
				fi
		fi
	done
done

if [ ! -z "$1" ] ; then
	for each in ${tbmounted[@]} ; do
		mounts=$(mount | grep "sd$each")
		if [ ! -z "$mounts" ] ; then
			umount "/mnt/sd$each"
			rm -r "/mnt/sd$each"
		fi
	done
fi
calling the script directly mounts all drive and by:
Code:
./automount.sh kill
unmounts ALL drives, unfortunately, I haven't enable the luxury of unmounting one at a time. I am glad to accept improvements.
