Installing Software Globally

Hi;

I'm just starting out with linux.  I am running Suse 7.2 personal edition.

How can I install new software such that it is accessible by all users from any directory?

For instance anyone can type "perl foo" from any directory and run perl.

I would also like to do some development on my linux box.  I would like to set up a "classpath" variable such that linux will first check for classes, compiled files in whatever directory the user is currently in and then go to a central directory that would server as a "code dump".

Is there a config file somewhere where I can create and set such a variable once and have it be global to everyone, everywhere?

How?

Thanks in advance

Steve

software is installed in /opt (complex applications) and/or /usr/local/bin (single programs), usually

To add a special path to all user's PATH environment variable, use the shell start up file, like
    /etc/profile for shell (sh, ksh, bash, etc.)
    /etc/csh.cshrc for csh and tcsh

and modify the PATH variable to your requirements
