iwatch binary package in Ubuntu Xenial ppc64el

 inotify (inode notify) is a Linux kernel subsystem that monitors
 events in filesystems and reports those events to applications in
 real time.
 .
 inotify can be used to monitor individual files or directories.
 When a directory is monitored, inotify will return events for the
 directory itself and for files inside the directory.
 .
 iWatch is a Perl wrap to inotify to monitor changes in specific
 directories or files, sending alarm to the system administrator
 (or other destination) in real time. It can:
 .
   - Send notifications via email about changes.
   - Take programmable actions immediately, as emit alerts via
     XMPP (jabber) messages, WhatsApp or execute a local program
     or script.
   - Act as HIDS (Host-based Intrusion Detection System) or an
     integrity checker, complementing the firewall system in
     networks.
 .
 iWatch can run as a simple command, as well a daemon.
 .
 A good example of iWatch usage is to monitor the pages directory
 in webservers to notify, in real time, about defacements. Another
 example is to synchronize configuration files between machines,
 when they are changed, as in DHCP servers acting in failover mode.
