Specifies the Java version of the current Linux Shell.

Installed with RedHatLinux5.4, the system comes with Java1.4 by default, but now generally use Java1.6, java1.6 PATH is/usr/java/jdk6 current PATH =/usr/lib/qt-3.3/bin: /usr/kerberos/bin:/usr/local/bin:/usr/bin:/home/bardwu/bin:/usr/java/jdk6/bin: /home/B

When Red Hat Linux 5.4 is installed, the system comes with Java 1.4 by default, but now Java 1.6 is generally used. The path of java1.6 is/usr/java/jdk6.

Current PATH =/usr/lib/qt-3.3/bin:/usr/kerberos/bin:/usr/local/bin:/usr/bin: /home/bardwu/bin:/usr/java/jdk6/bin:/home/bardwu/bin

We need to use the. bash_profile file in the default directory.

. Bash_profile is like this:

1. #. Bash_profile
3. # Get the aliases and functions
4. If[-F ~ /. Bashrc]; then
5. .~ /. Bashrc
6. Fi
8. # User specific environment and startup programs
10. PATH = $ PATH: $ HOME/bin
12. Export PATH

We need to modify this line: PATH = $ PATH: $ HOME/bin

Change to: PATH =/usr/java/jdk6/bin: $ PATH: $ HOME/bin

Execute this script. bash_profile

Try this way: java-version will show that Java is 1.6.

If it is modified to: PATH = $ PATH: $ HOME/bin:/usr/java/jdk6/bin

Oh, execute the script.

Let's take a look at the java version or java1.4.
