file-monitor
file-monitor is a simple Perl script to monitor a directory path for new files, updated files and deleted files. It can be set to look for new files in a given interval of seconds (e.g.: -n 30) and also can be set to check for updated and deleted files in another interval of seconds (e.g.: -c 12) Download: https://github.com/trizen/perl-scripts/blob/master/Monitoring/file-monitor
