Php function exec() is needed for TYPO3?

Question

Any one explain me exec() function is needed for TYPO3?

If yes than describe in which typo3 functionality depends on this function. if i have disable this function then what happening in typo3? which functionality will not work after disable this function...

Thanks...

Answer 1

A single search for "shell_exec" on typo3's source code finds two potential matches :

• SpellCheckingController.php , which calls Aspell functions, for spell checking purposes for the htmlArea RTE extension
• Scheduler.php calls Unix at and atrm functions

So, these are not vital functionalities, but you may have to disable manually the spell checker for your textareas (As I understand in the documentation ). As for the scheduler, it won't cause any problem if you don't intend to use it.

Answer 2

Depending on which exec function you disable you might loose the possibility to use the mighty tool ImageMagic/GraphicsMagic for resizing and modifying images. It is not vital, but restrict you or your editors in using images.
