以可移植的方式以编程方式打开文档

Question

is the following command working under Unix&Linux?

ProcessBuilder prcbdoc = new ProcessBuilder("cmd","/C","start", "Documentation.doc");       
            prcbdoc.directory(new File(currentDir+"/docs/"));
            prcbdoc.start();

I'm not sure because of the "cmd" "/c"

What would be an Linux CentOS equivalent command?

Answer 1

No, it doesn't work. From Java documentation:

a command , a list of strings which signifies the external program file to be invoked and its arguments, if any. Which string lists represent a valid operating system command is system-dependent . For example, it is common for each conceptual argument to be an element in this list, but there are operating systems where programs are expected to tokenize command line strings themselves - on such a system a Java implementation might require commands to contain exactly two elements.

To open a document in a portable manner using AWT :

if (Desktop.isDesktopSupported())
 Desktop.getDesktop().open(documentPath);

Answer 2

No, this would not work on Linux (or any other Unix, or on the Mac) due to the "cmd /c" and the "start". On the Mac, you'd say "open Documentation.doc" .The various Linux desktops have their own versions of the start/open command: gnome-open for the Gnome desktop, and the FreeDesktop semi-standard xdg-open are some possibilities.

编号cmd和/c仅与窗口相关。
