Bash Script that backs up MySQL Database
===

I wrote a script and I keep getting the following errors.  access denied for user 'zul'@'localhost (using password:yes) when trying to connect

proj: 43: [d: not found

proj: 43: [d: not found

It's not reading the input d nor is it connecting to MySQL. Any Ideas? 

Here is my Script:

    #!/bin/bash

    tstamp=$(date +$s) 

    #Dump or Update
    if [ -z "$1" ]; then
	  echo -n "What do you want to do? [D]ump or [U]pdate: "
	  read parm
    else
	  parm=$1
    fi
 
    #Database Password
    if [ -z "$2" ]; then
	  echo -n "What database are you using?"
	  read dbname
    else
	  dbname=$2
    fi

    #Database User
    if [ -z "$3" ]; then
	  echo -n "What database user are you using?"
	  read dbuser
    else
	  dbuser=$3
    fi

    #Checks if the directory exists
    if test ! -d "/home/zul/sql/backup"; then
	  mkdir /home/zul/sql
	  mkdir /home/zul/sql/backup
    fi

    mysqldump $dbuser -p$dbpass $dbname > /home/zul/sql/backup/$tstamp.$dbname.sql

    if [$parm = d ]; then
	  mysqldump $dbuser -p$dbpass $dbname > /home/zul/sql/backup/$dbname.sql
    elif [$parm = u ]; then
	  mysqldump $dbuser -p$dbpass $dbname < /home/zul/sql/backup/$dbname.sql
    else
	  echo " d or u option only! (lower case)"
    fi
