inotifywait

 
Waits for changes to one or more files. More information: https://manned.org/inotifywait.
 
  • Run a command when a file changes:
     
    while inotifywait {{path/to/file}}; do {{command}}; done
     
  • Be quiet about watching for changes:
     
    while inotifywait --quiet {{path/to/file}}; do {{command}}; done
     
  • Watch a directory recursively for changes:
     
    while inotifywait --recursive {{path/to/directory}}; do {{command}}; done
     
  • Exclude files matching a regular expression:
     
    while inotifywait --recursive {{path/to/directory}} --exclude '{{regular_expression}}'; do {{command}}; done
     
  • Wait at most 30 seconds:
     
    while inotifywait --timeout {{30}} {{path/to/file}}; do {{command}}; done
     
  • Only watch for file modification events:
     
    while inotifywait --event {{modify}} {{path/to/file}}; do {{command}}; done
