Alright, I'm not completly sure how to phrase this, so please let me know if it doesn't make any sense! I am currently writing a program to add a header to all my .h / .c /.java files, etc. So if I add my folder where my application's .class files are to the system path, i can then do the java myApp. Correct? So I want my program to know what folder it has been called from. What i mean by this is: For example, if, in *nix, do you 'ls' it know what directory it was called from. I am looking for the equiv in java. Hope this made sense!

System.getProperty("user.dir");

To get a list of properties use this:

public static void main(String[] args) {    Properties p = System.getProperties();    for(Enumeration en=p.propertyNames();en.hasMoreElements();) {        String temp = (String)en.nextElement();        System.out.println(temp + "=" + System.getProperty(temp));    }}

this works, but truncates some entries:

public static void main(String[] args) {    System.getProperties().list(System.out);}

I can't try that atm, but I assume (given that you replied =)) that will tell me the dir my app was called from?

Yes. "user.dir" shows the directory that you were in when you typed the java command. Or where it was called from if someone clicked a jar or ran from an IDE.
