Enviroment Variables

Is there any such thing as environment variables in Linux? I have Java's JDK and JRE downloaded and installed in folders... Now I need my environment variables to point to them.

Re: Enviroment Variables

Type

env

to see all environment variables. In bash, you can set new ones with

export VARIABLE=value

.

Hope that helps...

If you want to define the classpath:

export CLASSPATH=.:/path/to/your/classes:/another/path

unlike windows, path separators are colons, not semicolons

Re: Enviroment Variables

It's usually better to add things to CLASSPATH or PATH, instead of overwriting them, as this may cause other applications to break.

For example:

export CLASSPATH=$CLASSPATH:/your/new/path/here

Re: Enviroment Variables

you can set these variables in your ~/.bashrc (or ~/.${shell}rc, if you're fancy) to have them be defined whenever you fire up a terminal, in particular on boot.

System wide changes can be done in /etc/profile.

Re: Enviroment Variables

If I add

export PATH='$PATH:~/jre1.6.0_06/bin'

to my file '~/.bashrc' would that work?

Re: Enviroment Variables

yes, but only for your account.

You could also place a script or soft link pointing to them in /usr/bin, /usr/local/bin or anywhere else that PATH is already pointing to.  This would keep things much simpler, in my opinion.

If you replace the single quotes with double quotes, then yes.
