JDU:/host-001e67a8d50b /log/today # inotifywait -hinotifywait 3.14Wait for a particular event on a file or set of files.Usage: inotifywait [ options ] file1 [ file2 ] [ file3 ] [ ... ]Options:    -h|--help       Show this help text.    @<file>           Exclude the specified file from being watched.    --exclude <pattern>                    Exclude all events on files matching the                    extended regular expression <pattern>.    --excludei <pattern>                    Like --exclude but case insensitive.    -m|--monitor    Keep listening for events forever.  Without                    this option, inotifywait will exit after one                    event is received.    -d|--daemon     Same as --monitor, except run in the background                    logging events to a file specified by --outfile.                    Implies --syslog.    -r|--recursive  Watch directories recursively.    --fromfile <file>                    Read files to watch from <file> or `-' for stdin.    -o|--outfile <file>                        Print events to <file> rather than stdout.    -s|--syslog     Send errors to syslog rather than stderr.    -q|--quiet      Print less (only print events).    -qq             Print nothing (not even events).    --format <fmt>    Print using a specified printf-like format                    string; read the man page for more details.    --timefmt <fmt>   strftime-compatible format string for use with                    %T in --format string.    -c|--csv        Print events in CSV format.        -t|--timeout <seconds>                    When listening for a single event, time out after                    waiting for an event  for <seconds> seconds.                    If <seconds> is 0, inotifywait will never time out.    -e|--event <event1> [ -e|--event  <event2> ... ]        Listen for specific event(s).  If omitted, all events are        listened for.        Exit status:    0  -  An event you asked to watch for was received.    1  -  An event you did not ask to watch for was received    2  -  The --timeout option was given and no events occurred          in the specified interval of time.Events:    access      file or directory contents were read    modify      file or directory contents were written    attrib      file or directory attributes changed        close_write file or directory closed, after being opened in writable mode    close_nowrite   file or directory closed, after being opened in read-only mode        close       file or directory closed, regardless of read/write mode    open        file or directory opened    moved_to    file or directory moved to watched directory    moved_from  file or directory moved from watched directory        move        file or directory moved to or from watched directory    create      file or directory created within watched directory    delete      file or directory deleted within watched directory    delete_self file or directory was deleted    unmount     file system containing file or directory unmounted
