Symbolic links

Used in the context of redirecting the path of a file to a new destination. Used on eg the HPC system to redirect from the /home/user space (which is subject to a small disk quota) to eg /work/user space (which has a much larger disk quota)

ln -s /work/rzepa/run /home/rzepa/run

ln -s /path/to/file /path/to/symlink
