  if [ ! -z "$num" ]
    then
    if [ ! -z "$pass" ]
    then
    y=$( echo $num | sed 's/[0-9]//g' )
        if [ -z "$y" ]
        then
        for (( i=1; i<=$num; i=i+1 ))
            do
                useradd $name$i &> /dev/null
        # userdel $name$i &> /dev/null
                echo $pass | pass --stdin $name$i &> /dev/null
            done
        fi
     else
