Rodrigo Sasaki's questions

I'm using zsh as my shell, and I'm trying to configure my environment.

I usually define my $JAVA_HOME variable by creating a file:

/etc/profile.d/java.sh

with the following content

export JAVA_HOME=/path/to/jdk
export PATH=$JAVA_HOME/bin:$PATH

then I logout and back in, and it all works, but for some reason the PATH variable is not set. It recognizes JAVA_HOME, but not the new PATH, see this terminal snippet:

~  echo $JAVA_HOME
/usr/lib/jvm/jdk1.8.0_05
~  echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

and I confirmed it by trying to run a command form the jvm

~  java -version
zsh: command not found: java

the PATH doesn't include the $JAVA_HOME as it should. is there something else I should check?

I have checked that if I run:

source /etc/profile.d/java.sh

it all runs correctly and my variables get set as they should, but shouldn't the scripts in /etc/profile.d run automatically?

I was doing some alterations but in one I messed up.

I changed the permissions of almost everything inside the /usr folder to my own user. It didn't change everything because it failed in the middle of the execution, I still have /sbin, /share and /src assigned to root.

the command I ran was this (this was executed while inside /usr):

sudo chown -R myuser:myuser .

Is there any way for me to revert this?

If I run:

sudo chown -R root:root .

I get this error:

sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set

I had bash as my default shell even though I was only using zsh.

I always started it myself by opening the terminal and typing zsh.

Today I decided to use it as my default shell. So I found this link and ran the following command

sudo chsh -s $(which zsh) john

where john is my user.

It all worked fine until I tried accessing my bank's website and noticed that the symbolic link I had created for the Java Chrome Plugin didn't work anymore.

I tried deleting it and creating a new one via zsh with this command:

sudo ln -s /opt/jre1.7.0_55/lib/amd64/libnpjp2.so

but it didn't work. Should I do something different now that I'm using zsh? How do I get my symbolic links working again?

everyone!

I had to change keyboards at work and they gave me a mac keyboard that wasn't in use. I configured most of it to the point where I can use it, but I noticed that I need to press the fn key to activate the Functions F1~F19 and I was wondering if there is anyway I could flip that.

So what I want to do is have the Function keys as default, and need to hit fn whenever I want the other function of the key, such as Volume Up or Eject Disc

I am very new to Ubuntu, and I'm having a problem that I don't know how to get it fixed. I even tried looking it up on the web for answers, but maybe I don't know the right terms to search for it.

I work with IntelliJ IDEA, an application for development. And I am very used to the keyboard shortcuts, but when I made the switching from Windows XP to Ubuntu 13.10, some shortcuts don't work anymore. For example, such as;

• Ctrl + Alt + ←
• Alt + F8

Is there any reason as to why? and are there any fix for this? Or maybe just something to guide me on my searching

Thank you all very much in advance.
