The "&" tells bash to fork the process into the background so you get
your console / xterm back. If you don't use the "&" at the end, the
mysqld_safe process will run in the foreground and will remain 'tied' to
the console you started it from ... so if you close the console / xterm
you may kill the mysqld_safe process.
Ah, it's not part of the mysqld command itself. Got it.
Right. It's a process-control aspect of how the shell itself works.
The genesis of this in Unix is described in the "Process Control"
section of this document by Dennis Ritchie:
