Write a file Can't Post
Im trying to create file into a dir. But im trying to make the file path configurable . How would i get the file path from a variable or whatever.

$brconfig::$config_logfilepath is the file path i want to use set in brconfig.pm . brconfig.pm creates a configurable file where other config settings are set.

So how would i get the file path so it writes in the file in that dir. Not sure what to do.

could i do somthing like
open (ConsoleCommand, '>>$brconfig::$config_logfilepath\ConsoleCommand.txt');
print ConsoleCommand "command flymode ObjectID\n";
close (ConsoleCommand);

You could try something like that but variables can't be in single-quoted strings, use double-quotes instead and use a forward slash instead of a backslash in the path:

Code
open (ConsoleCommand, ">>$brconfig::$config_logfilepath/ConsoleCommand.txt") or die "$!";
Keep in mind that '>>' opens for appending to an existing file or creating a new file if one does not already exist. Use '>' if you want to create a new file each time you open the file.

Ok that's what I did wrong. But it created the file in C:\ and the FDSLogFilePath = C:\test\Server\data\


It does this when it reads the brconfig if that helps at all
if (/^\s*FDSLogFilePath\s*=\s*(\S+)/i) { $config_logfilepath = $1; }

else it will show an error

OK, I'm not sure what you're getting at. If the file path is C:\test\Server\data\ then it makes sense it created the file on the C drive.

OK, well, I have no idea why that is. Print the value of $config_logfilepath while the script is running to see what its value is.
