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?<

Simply do:

mkdir /path/to/your/potentially/existing/folder

mkdir will throw an error if the folder already exists. To ignore the errors write:

mkdir -p /path/to/your/potentially/existing/folder

No need to do any checking or anything like that.

For reference:

-p, --parents no error if existing, make parent directories as needed http://man7.org/linux/man-pages/man1/mkdir.1.html
