 Create a file with some [Falco rules](Rule-syntax-and-design). For example:
 ```
-write: (syscall.type=write and fd.typechar=f) or syscall.type=mkdir or syscall.type=creat or syscall.type=rename
-interactive: proc.pname = bash or proc.pname = sshd
-write and interactive and fd.name contains sysdig

 And you will see an output event for any interactive process that touches a file with "sysdig" or ".txt" in its name!
