My program does some fairly intensive operations, so I use a scratch file in order to speed things up. I use the following Java code:
File scratchFile = new File(System.getProperty("java.io.tmpdir") + "WCCTempFile.tmp");
if (!scratchFile.exists())
scratchFile.createNewFile();
This code works just fine on Mac OS X and Windows.
I'm confused about execute file permissions not behaving as I expect. Probably because my expectations are wrong. Anyway:
I have a script file, for simplicity is just called s, located in ~/bin. For the sake of this example, the file contains just the following lines:
#!/bin/zsh
echo "Test";
Very simple.
I have downloaded a jar file vnaj2.8.5b.jar this file is a Linux application for a network analyzer. The jar file contains numerous files. I have java 6 installed. I need help in installing/running this application in Ubuntu 12.04. I can take any individual file within the package and under properties can associate it with java.
After some play around with rooted devices, I got stuck on the files. Let's say we have a file somewhere in the root folder which I want to read/write from my application.
I am trying to execute in linux:
command[0] = "~/test/bin/runScript_sh";
Runtime.getRuntime().exec(command);
But get an exception
java.io.IOException: Cannot run program
error=2, No such file or directory
Probably because it can not evaluate tilde.
What can be done?
I am trying to call a bash script from a java class .
This is my java program
import java.io.File;
public class RunBuild {
public static void main(String[] args) {
File wd = new File("/home/sai/Jan5WS/ATCore/bin/");
System.out.println("Working Directory: " + wd);
Process proc = null;
try {
proc = Runtime.getRuntime().exec(" .
I am getting the error
fopen(/var/www/photos/testphoto.jpg): failed to open stream: Permission denied
when PHP is attempting to write a file to /var/www/photos, whose directory permissions are
drwxrwsr-x 3 root www-pub 4096 Oct 11 01:46 photos
I have already added apache2 user www-data to the group www-pub, why is it still unable to write files to the directory unless I chmod 777 /var/www/p
Hi,
I am wondering if there is a Linux application that can fix a file corruption issue I have. It is a FAT system on an SD card that I use in my digital camera.
I am using Ubuntu for development purposes.
As I work on the database side, there are a lot of things which require file permissions in order to access the data directory or some other according to the requirement.
Every time I get an errors like:
[ERROR] path/to/directory/ permission denied
To avoid it I have to log in as root root from the terminal and give access to that directory with:
