Waits for changes to one or more files. More information: <https://manned.org/inotifywait>.

• Watch a specific file for events, exiting after the first one:
  inotifywait path/to/file
• Continuously watch a specific file for events without exiting:
  inotifywait --monitor path/to/file
• Watch a directory recursively for events:
  inotifywait --monitor --recursive path/to/directory
• Watch a directory for changes, excluding files, whose names match a regular expression:
  inotifywait --monitor --recursive --exclude "regular_expression" path/to/directory
• Watch a file for changes, exiting when no event occurs for 30 seconds:
  inotifywait --monitor --timeout 30 path/to/file
• Only watch a file for file modification events:
  inotifywait --event modify path/to/file
• Watch a file printing only events, and no status messages:
  inotifywait --quiet path/to/file
• Run a command when a file is accessed:
  inotifywait --event access path/to/file && command
