The path that you are exercising to the binary of most commands is
revealed by the command "which".
For example, "which evolution" returns "/usr/bin/evolution".

In some cases the install will create a directory which contains the
full application, and then which will show only the link to the
executable.  However if you then do " ls -al path/file" using the info
returned by the which command you will see the link that is being
followed.


[me at localhost ~]$ which evolution
/usr/bin/evolution
[me at localhost ~]$ ls -al /usr/bin/evolution
lrwxrwxrwx 1 root root 15 Nov  4 19:52 /usr/bin/evolution
-> ./evolution-2.8
[me at localhost ~]$ ls -al /usr/bin/evolution-2.8
-rwxr-xr-x 1 root root 140248 Oct 27 07:02 /usr/bin/evolution-2.8
