recipe of not giving expected results

I want to execute a command only if the given directory "/local/update/" doesn't exist

My recipe code is below

execute 'test' do
   command "some command here"
   not_if { ::File.directory?("/local/update/") }
end

also tried

not_if { ::File.exist?("/local/update/") }

Even when the directory is present it still runs the command. I have checked in client.log and this step is not skipped

Adding an answer as there is a better (in-built) way to make the execute resource idempotent. Instead of skipping it using not_if, we can use the creates property. From the documentation:

creates

Ruby Type: String

Prevent a command from creating a file when that file already exists.

Example:

execute 'test' do
   command "some command here"
   creates '/local/update/'
end

With this implementation, the command will run if the /local/update/ path does not exist. Otherwise it will report as "up to date":

* execute[test] action run (up to date)
