Either the file was created, or an error message was issued explaining why it wasn't.	[reply]

Looks fine to me too, although I suspect you don't need '+>' mode, but just '>'. Read the following tutorial that covers modes for opening files: perlfile. Do you get any errors when calling open or print?	[reply]

The others have asked the proper questions. I'm just here to suggest File::Temp.	[reply]

It works on my system. What other information can you provide? Be Appropriate && Follow Your Curiosity	[reply]

The previous monks' questions are good ones. Please take some time to answer them. My thoughts are that change the file name and the folder you're writing to. Temp is pretty common folder name and data.txt is also fairly common file name. It's conceivable that another process is interfering. Hence why I suggest trying to write to a different location with a different name. See if that changes it things. If it does, you know it has to do with your environment and you could do with some investigative work.	[reply]

or to get simple on it, make the file name Data.$$.txt and have the program print to STDERR "writing to Data.$$.txt" or some such message. $$ is the PID for the program, random enough in this case. Be Appropriate && Follow Your Curiosity	[reply]

When I run into a problem with code that writes to a file, I like to test it writing into the same directory the perl is being run from to make sure it's not a file path issue. i.e.: `open($CONFLICTS, '+>', "data.txt") or die $!; print $CONFLICTS "@data";` [download] Then it's easy to check in the same folder your perl code resides to see if it wrote the file.
