A more reliable method (bot still not infallible) would be to create a temporary directory. You can then happily write files there and set a trap to clean up when your script ends. If you have mktemp installed then consider something like this:-
If the variable DEBUG has a value then the directory is not removed so you can go and have a look afterwards. If you don't set it or set or you actively unset it, then the trap will be switched on and the directory removed at the end to reduce the risk of conflicts later.
If you don't have mktemp then you can just try it using:-
