Ubuntu :: Set Java Path For All Users - Including Root
Jan 27, 2010
I am trying to set my java path so that it is in effect for all users including the root user. I set the path correctly in /etc/profile and that works for my personal user, but when i try to run the same commands using sudo, i get messages saying that it can't find the java path.

I have local Wordpress database that got corrupt as a result of an abrupt power outage (I wasn't even editing it!).
Since the system I am dealing with is pretty static (and old), I just want to restore that database file (or collection of files) from a nightly backup.
But I don't know which files I should be restoring. The WordPress blog in question is installed under a local user account in an old Linux server (FC4).
I checked the wp-content directory, but apparently this is not where the content is:
Any idea which file(s) I should be restoring and what their path is?

I have a ELRO C903ip.2 camera. I want to use it on zoneminder but am having trouble connecting. I have set a basic account of visitor with username and password both set as visitor.
The question is what is the syntax to the cameras ipaddress via http passing the u/n and p/w at the same time as part of the http string? I have tried the web page: [URL] .... to no avail, i must be missing something pretty obvious but just can't see it for looking.

what I'm doing, but I'm implementing some automatic security protocols on a ubuntu system, and I need to see a list of all users, including system ones. The reason for this is that I created a system user with a specific UID, and I forgot it. The 'user' command only lists the nonsystem users.

I'm having a CentOS 4.4 X86_64 server. Without any warning all users account including root got disabled. As the server was still logged in as root, i was able to enable all the users account. But for root i couldn't.Without thinking i rebooted the server and except root, other users can log in to the server. I should've tried to enable root account from the /etc/passwd. But now i realize its too late for that.Now i want to change from root: x:0:0:root:/root:/bin/false to root: x:0:0:root:/root:/bin/bash. Can anyone guide me to accomplish this or is there any other way to fix this?

My install of 11.4 has been running perfectly for for several weeks now. But- (always a but) today it started acting up. I cannot log in to any user account including Root after logging out. After a cold boot I can log in again anywhere but after logging out I have to reboot again then I can get back in to any account once. After logging out any attempted log in causes the splash screen to blank for a few seconds and then it comes back with the previous successful user name log in but typing in the password blanks the screen a few seconds again. Clicking on a user account also blanks the screen a few seconds and then it again comes back with the previous log in users name.

I'm fighting my way through JAVA. But have hit another wall. Basically I need to to set paths in java so it can set/read files/director for Linux,Mac and windows.
The tutorials I'm using says to do this through the FileSystems class eg
Code:
However this reports it is missing, so a look on line says I need the headers so I set them with
Code:
This gives the following error
This has me totally confused as the tutorial shows this and checking online shows this, do I need to link in libraries or something like that?
I'm using the latest Ubuntu 11.04 and netbeans.

I have downloaded java and installed it with chmod +x and then ./bin package.
Hereunder is an output from CLI (putty)
I understand that the system knows the java is in a wrong place but if I do java -version it finds it correctly. I don't know and I don't understand how do I need to tell the OS that the java is somewhere else, I just did that with export java home and java path but still dosen't work, it keep tells when I do whereis java "java: /usr/share/java"
Here is another output:

I have a program that has a GUI which I have placed in /usr/local/bin however when I invoke the program I receive the following error:
Unable to find a supported JDK or JRE version. Version 1.3.1 or higher is required. Check your installation and use +javahome to specify the JDK or JRE location
I have since installed Java into the usr/local/ directory however I am now just totally Lost! Additionally, I believe that i have tried to install Java several times with no luck.
Questions:
1) Where should java be installed to have system wide access to all programs?
2) How can I place the Java location in my $PATH? here I am going to need very easy and detailed instructions?
3) Is there a way to ensure that the location where I intall java gets updates?

What steps have to be followed for having customized contents of PATH environment variable whenever new users are created? I require this in order to include a special directory into PATH variable; and this has to be a default one for all the newly created users.

I am failing to set PATH for all the users on a linux box(Fedora 8), permanently. Basically, I have installed two different versions of python(2.5 & 2.7) Python2.5 path is /usr/bin and it is set by default for all users(not by me, also i don't know how ) and it is working fine.
Python2.7 path is /usr/bin/Python27/bin, so tried this:
PATH=$PATH:/usr/bin/Python27/bin
And it worked only for that particular session and for only root, as I set path from root user. So, i need this to be set for all the users on the linux box, including root, more importantly as permanent. So if any user types "python27" at the command prompt, it should give python2.7 prompt.

I want to ask how i set Linux class path for mail.jar and mysql-connector.jar. I have set the class path for java with the command.
Code:
when i do java -version it's work fine.
Also if i want to know that what shell i am using how can i find it.Also what is the command for showing class path variables or how can i see my JAVA_HOME class path.Means after setting the class path for above two files how can i see that these files have added.
When i write echo $CLASSPATH or echo $JAVA_HOME it shows nothing no error but again shows the prompt.
One thing more i want to run a java program on Linux it is in a package (named asteriskproject). It consist of 10 java files. I have run this program on windows using netbeans IDE.For this program i need to set my Linux class path for the above mentioned files, and this is my first time that i am running any program on Linux. So i want to ask how can i run my program. Simply put this asteriskproject directory in any folder and run the main file using javac. Is it right way to run the program that consist of package ?

I've installed rubygems on ubuntu, but it has a known issue that the rubygems' bin/ directory is not in the PATH. I know about exporting the PATH variable, and adding it to .bashrc, but I'd like to configure it so that every user has it on his PATH, even if he tries to run it with sudo. Where should I export the PATH variable then?

I want to add a path (/usr/sys) to the global $PATH. I will use this to test commands and scripts, which I don't want to be mixed up with regular commands. I've added the path to /etc/environment. When I start a terminal session under my user account, the path is included in the $PATH variable. However, when I start a root terminal, it is not. Is there a way to to change $PATH on one place where it will also affect the root terminal, or do I have to change it on 2 locations?

How do I set the PYTHONPATH for the root user only? Or at least add to the python path for the root user? I need to read from the /var/log/apache2/access.log in my python script, so I need to use sudo for my script to be able to read from it.I tried setting the PYTHONPATH in /root/.bashrc but that didn't work. I don't want to use a .pth file because I don't want the directory to be on the path for all users due to import collisions.

After upgrading to CentOS 5.4, my root path seems screwed.The issue is present for CRONJOBs that run as the root user as well as when I su to the user through SSH.
I need the following path ALWAYS:
PATH=/sbin:/usr/sbin:/bin:/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/X11R6/bin
It currently only gives root:

I'm working on my first .deb package. I need to add the /usr/sbin directory to $PATH for root. I think the easiest way to accomplish this is to add a little code to the postinst file.
