This is the wrong place for this kind of questions. You should try a programming forum, the programmers stackexchange or even reddit. — Alexander_Winter 1 min ago

@danielfranca you can, but you usually shouldn't. OP, your approach does not make sense - instead of copying your script into all directories and then executing the copies, write a function that takes a directory path as an argument and does whatever you want to do with it. Then just call it once for every directory you want to process. Also, you should spend much more time learning the basics before asking questions on SO, your code has multiple trivial errors. SO is for questions by professional and enthusiast programmers, not for absolute beginners with no programming knowledge. — l4mpi 1 min ago

@MicroVirus Read this as an example: programmers.stackexchange.com/questions/198284/… if you still don't agree shrugs — Lews Therin 2 mins ago

@Trengot This "somewhere" you speak of is not SO. There are more than enough resources for beginners to get started, and of course SO would not be empty without them. The mission statement of SO is to create a repository of useful programming knowledge, and thus questions are expected to be useful to a general audience of programmers and not just OP. This by definition excludes trivialities; it's why the downvote arrow tooltip includes the phrase "not useful". SO is a knowledge repository similar to wikipedia, not a forum, tutorial resource, mentoring site, or online debugger. — l4mpi 1 min ago

Sorry to revive this, but at least for me... die is far faster to write than exit... I'm starting to use exit because it's more readable to non-PHP-programmers, but die is just faster to type when you're in a hurry. Also, by the way I type, I don't have to change my hands' position to write die. — Alejandro Iván 2 mins ago

Funny, windows return codes are more descriptive than unix codes (although, both are a programmers choice) — Dieter Lücking 35 secs ago

Fixed so it works properly in SQL Server at least to help others programmers out. — laylarenee 13 secs ago

You might read the book The Definitive ANTLR Reference: Building Domain-Specific Languages. There is also an antlr4 book with a very similar title. You can find nice examples in it and good explanation of the basic terms, concepts, etc. — lp_ 2 mins ago

@aw04 this is a bad fit for Programmers - it would be quickly voted down and closed over there, see meta.programmers.stackexchange.com/questions/6483/… Recommended reading: What goes on Programmers.SE? A guide for Stack Overflow — gnat 2 mins ago

Comments are for the benefit of the other programmers in your organization, so they'll understand your code. So you should comment in a way that they'll understand. — Barmar 2 mins ago
