Hi Folks, I am new to Linux world. When i type env, it shows bunch of environment variables and some of them are not what i would like. somehow i messed up those variables' values but i don't know which file i should open to get an access to those variables and edit those values. could you please help with this? thanks.
Careful, you could make the whole OS break down. Unless it's already been corrupted, you probably should be content with overriding them as needed. For example, say I want to work with Java 5, but everyone else is still on JDK 1.4, so I want to override the path and JAVA_HOME (or on my servers, add them, since they're not standard OS settings). The best place for me to do than on a RedHat/Fedora system is in /home/timh/.bash_profile. Just set and export JAVA_HOME and update exported PATH=$JAVA_HOME/bin:$PATH.
How environment variables get set is largely a matter of where you are and how that particular distro manages that part of the system. The only real way to tell - unless there's documentation for your distro - is to manually trace the process. Certain key files are /etc/profile, /etc/skel (where prototype profiles for newly added users are defined), and the $HOME profile file(s) used for the shell you're running. For their names, consult the man pages for your shell of choice.
