command for finding java version
hi
what is the command to find java version running in the computer. java -version is not working. thanks |
What do you get typing java -version?
|
[bala@localhost eclipse]$ java -version
bash: java: command not found |
Try using the full path, when doing so, you may even get the version from the path, like here:
$ /usr/lib/jre1.6.0_01/bin/java -version java version "1.6.0_01" Java(TM) SE Runtime Environment (build 1.6.0_01-b06) Java HotSpot(TM) Server VM (build 1.6.0_01-b06, mixed mode) |
thank u
i have two logins .in one login java command works but in the other it does not . i have mentioned the path variables in both users .bash_profile. |
I suggest to double check $PATH for both users and make sure the path is correct and don't point to a old directory etc. If the path is correct, can both of the user actually run the program when run it with the full path?

thanks again,
i have checked the path its fine , but one thing i am intrested to understand is that when i press tab it shows all the commands (i hope i am right). in one login the command java is displayed . in the other it is not ,who actually updates the command [bala@localhost eclipse]$ whereis java java: /etc/java /usr/lib/java /usr/share/java # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs export JAVA_HOME = /usr/java/jdk1.6.0_02 PATH=$JAVA_HOME/bin:$PATH PATH=$PATH:$HOME/bin export PATH unset USERNAME ~ ~ ~ ~ ~ ~ ~ |
