How to create a link xxx to /home/jake/doc/test/2000/something/?
Assume the xxx is created under /home/jake and you currently under /home/jake. When you do "cd xxx", you directly go to /home/jake/doc/test/2000/something/.
Symbolic or soft link (files or directories, more flexible and self documenting)
# Source Link ln -s /home/jake/doc/test/2000/something /home/jake/xxx
Hard link (files only, less flexible and not self documenting)
# Source Link ln /home/jake/doc/test/2000/something /home/jake/xxx
More information: man ln
