How to use Bash to create a folder if it doesn't already exist?

Question

#!/bin/bash
if [!-d /home/mlzboy/b2c2/shared/db]; then
    mkdir -p /home/mlzboy/b2c2/shared/db;
fi;

This doesn\'t seem to work. Can anyone help?<

You need spaces inside the [ and ] brackets:

#!/bin/bash
if [ ! -d /home/mlzboy/b2c2/shared/db ] 
then
    mkdir -p /home/mlzboy/b2c2/shared/db
fi
