In my bash script I do:
mkdir product;
When I run the script more than once I get:
mkdir: product: File exists
In the console.
So I am looking to only run mkdir if the dir doesn't exist. Is this possible?

You can either use an if statement to check if the directory exists or not. If it does not exits, then create the directory. You can directory use mkdir with -p option to create a directory. It will check if the directory is not available it will.
mkdir WILL give you an error if the directory already exists. mkdir -p WILL NOT give you an error if the directory already exists. Also, the directory will remain untouched i.e. the contents are preserved as they were.
1 Answer. Show activity on this post. The mkdir command will create any folders that do not exist in the specified path, unless extensions are disabled ( setLocal enableExtensions ) - regardless, it will not destroy a directory and create a new one with the same name.
-p: A flag which enables the command to create parent directories as necessary. If the directories exist, no error is specified.
Do a test
[[ -d dir ]] || mkdir dir
Or use -p option:
mkdir -p dir
