Now I've created my program, and I've saved it to a php file. <?php echo '<p>Hello World</p>'; ?> I know that I need to use something like http://localhost/myfile.php , but where do I put the file, so Apache will see it? 回答1: Pick a name for it lets use hello.php for this example. On Ubuntu the folder is /var/www/html , NOT /var/www . You will need root access for that. So you save the file as /var/www

However if I do a ps $pid it shows the main script process instead of the process of the java program. It obtains the correct process when I omit the eval, but in order to get some of the complicated arguments to work correctly I need to use it. Any idea of how I can get the PID of the java program when it's executed within an eval command? 回答1: Your ampersand is backgrounding the eval line,

How can I do this? Can I do it? Something like "cscript test.vbs workFolder:'C:\temp\'" perhaps? Bonus question: Is it neccessary to clean up the passed variable with "Set workFolder = Nothing" or does VBSCript do that

This script needs to be ran as part of the install and thus must be ran only once (either after the entire OS install or on the first boot). It cannot be ran on the host system, as it depends on the hardware IO which exists only on the target. An additional, minor, constraint is that the rootfs is mounted as read only, but I guess that can be avoided by having the script re-mount as rw and again remount as r after the execution or something along those lines. Any help is appreciated. 回答1:

Ii'm thinking I'd like VB6 to read in flat text script files for me and then lex/parse/execute them. I have good programming experience, and I've built a simple C compiler, as well as a LOGO emulator before. My question is: Are there any tools that I can use, like Lexx/Yakk/Bison to help me? How should I approach this problem in regards to lexing, parsing, and feeding the commands back to VB6 so I can handle them? Is this

I'm using the latest require.js combined with jquery as my module loader. I am using the data-main attribute to point to a config file with a baseUrl .
