By default ln creates [hard link](http://www.linfo.org/hard_link.html) and requires existance of TARGET file/directory. If we add `-s`(--symbolic) to the command, [symbolic link](https://www.computerhope.com/jargon/s/symblink.htm) will be created.

The shell reports the PID of each process that is running in the background (unless you start more than one process in a pipeline, in which case the shell reports the number of the last process). You can also use the `ps` command to find the process ID number of commands.
