I'm new to linux but I use linux a little at school and by connecting through a shell at home. Anyways, I just installed linux a little while ago and I opened a shell and tried to compile some java code by going to the directory of the code and typing "javac someCode.java" like I do at school but it says the command is not found.

I previously had installed the java runtime environment and I just went to go and try to install the java development kit but it says it was already installed.

Is there some sort of path I need to set for the shell to look for the java compiler? Thanks in advance.

Edit:
I have added aliases to my .cshrc file at school and I just found a bashrc file and csh.cshrc file in the /etc folder. Sorry, I'm really new to all of this. Anyways, I'm geussing I have to edit the bash file? Can anyone point me to a good tutorial of scripting for these files???

HI,
When I first joined this forum I made a fairly long synopsis of who I am and what I wanted to do with Linux. I thought I posted it but now I can not find it anywhere. No doubt I messed up somehow!

I am developing a Java stand alone application that will require some server side Java Servlets to manage the marking, registration, install and deployment phases. I have a spare Windows 7 PC that I have converted to the Debian Linux system successfully...

I currently use LunarPages as my ISP and host to 3 domains. If I use them to host my Server Side processing they use Resin 3.x for the web server and my contract with them provides me with one 'MySQL' database system...

Next on my own server I will install the Resin version that LunarPages requires along with their required version of the Java EE.

I have 3 ways to eventually deploy my Java stand alone application
1. Use LunarPages to host my Server Side Servlet command...
2. Use the Google AppEngine service...
3. Use my own Linux Server for deployment purposes...

This message is an intro and does not have any specific question yet...
Perhaps someone may offer some suggestions for me or critique my objects...

Regards,

Jim Crowell

hello, I changed ubuntu 11 to ubuntu 14.10.

At the time of installation, I chose only open ssh for installation and I installed successfully.

Code:

 sudo apt-get install apache2

I see:
Code:

Unable to locate package apache2

It is clear I have not apache2.now,I want to connect in internet and install it.

Hi experts,

so the steps to install kvm is this:

Code:

sudo apt-get install qemu-kvm libvirt-bin bridge-utils virt-manager

according to this webpage: http://www.howtogeek.com/117635/how-...nes-on-ubuntu/

Can I make this simpler?

I want to do just one command: sudo apt-get install kvm, and it should call and install all these packages.

Thanks

I probably do something wrong with $PATH when install Java JDK. Now when I type
startx, reboot, which,... I get command not found.

When I type: echo $PATH
It shows only: /usr/local/java/bin

I have setup a dual boot system with Fedora 21 and Arch Linux. The problem is that Fedora doesn't see my encrypted Arch installation. The installations are on separate partitions and do not share anything apart from hard disk space. I have run the following commands as root in Fedora:

Code:

grub2-install /dev/sda

Code:

os-prober

Code:

grub2-mkconfig -o /boot/grub2/grub.cfg

When I rebooted, Fedora was the only OS entry showing in the GRUB menu.

There was a suggestion from one of the members of the Arch forums that I should write the entry myself into /etc/grub.d/40_custom and then re-build the grub configuration or take the Arch entry from Arch's /boot/grub/grub.cfg and just paste it into the 40_custom in Fedora and rebuild.

How do I boot from a live Arch USB stick into the installed Arch and do as stated above? How would it work? Thanks in advance for your replies.

I follow the URL to install awstats , the installation process seems successful .

http://thelinuxfaq.com/90-how-to-ins...os-fedora-rhel

But when I try to run the report by
Code:

http://192.168.0.1/awstats/awstats.pl?config=mydomain.com ,

it pops the error.

Code:

Not Found

The requested URL /awstats/awstats.pl was not found on this server.

then I create /awstats/awstats.pl in DocumentRoot directory , now when I re-try to run the report , it display the program code of the awstats.pl but not show the report , would advise what is wrong ?
