#This does some fun password generation, it's ez so no explanation needed.


#Set this to your random device:
RANDOMDEV=/dev/urandom

#This function does all the work
function generar {
dd if=$RANDOMDEV count=1 2>/dev/null | uuencode -m -| head -n -2 | tail -n 1 | cut -c-$LENGTH
}
function help_menu {
cat << EOF

Usage: (-n Number of passwords | -l Length of passwords)

Example: $0 -n 5 -l 8

That will generate 5 passwords with 8 characters each.
EOF
exit 0
}

#Grab the options
while getopts n:l:h X

do case "$X" in
	n) NUMBER=$OPTARG ;;
	l) LENGTH=$OPTARG ;;
	h) help_menu  ;;
esac
done

#pebkac tests
if [ -z $NUMBER ]
	then echo "You must tell me how many passwords to generate. Use -h for more info."
	exit 1
fi
if [ -z $LENGTH ]
	then echo "You must tell me how many digits are in the passwords to generate. Use -h for more info."
exit 1
fi

#Here's the actual work
for ((n=0;n<$NUMBER;n++)); do generar ; done
