Is threadsafe using `cd path/ && zip -r name.zip directory/`

Question

I would like to zip a directory, but I need to use a full path and I need that the zip files starts in the directory, not in / .

That question was solved here: Command to zip a directory using a specific directory as the root

The answer would be basically to use this: If I want to zip full/path/to/directory/ in a file named myFile.zip, I would need to use the command

cd /full/path/to/ && zip -r myFile.zip directory/

Now, my question: is this threadsafe? without && (2 commands) would be unsafe, is && enough to make it threadsafe?

Answer 1

Saying command1 && command2 implies that command2 would be executed only if command1 exits with a return code of zero. If /full/path/to/ doesn't exist than the zip command wouldn't be executed.

Regarding the thread safety part, if you have multiple processes trying to create a file with the same name in a given directory, chances are that it'll lead to unexpected results.
