LINUX Create Executable Binary File

I'm newbie trying to learn about linux, Centos 6.5. Today I learned how to change from #./yourprogram in certain directory to #yourprogram. I want to share it here.

Condition:
I've just downloaded Eclipse for example. In tar.gz.
When I extracted the files in certain folder, I can run the program by calling #./eclipse.

Goals:
What I do want is to run a simple command $eclipse, then I can have my program running.

Answer:
Consider this as your program directory.
/usr/eclipse
it can be any directory.

This is the way.
#touch /usr/bin/eclipse
#chmod 755 /usr/bin/eclipse
#vi /usr/bin/eclipse

then put this inside.

export ECLIPSE_HOME="/usr/eclipse"
$ECLIPSE_HOME/eclipse $*

Finished!
