Email notification for new uploads to my RHEL server

[desmondlewissmith]

I'm a newb, but I'm wondering how hard it would be to do this:

I have a server that I receive uploads to daily.

I'd like to have a notification email sent to me telling me what files were uploaded and what time.

The uploads are typically large zip files and are always uploaded to a single directory by just adding a new directory with a numerical value for date and month as the naming convention then adding the zip file in that location.

Any help would be GREATLY appreciated.

It would be easy peasy.

Write a cronjob that runs every minute (or whatever you prefer) that monitors that directory. Keep track of files in it with the use of a master list - just a text file containing each new file, one per line. A cronjob just means a scheduled run of whatever program you specify. In your case, it would be a simple bash script. An example of your script would be:

#!/bin/bash
dirToWatch=/data/uploads
masterList=${dirToWatch}/master.txt
files=$(find $dirToWatch -maxdepth 2 -type f -name '*.zip')
for file in $files; do
  grep -q $file $masterList
  if [ $? -eq 0 ]; then
    echo $file already in $masterList
  else
    # new file - add it to the list
    echo adding $file to $masterList
    echo $file >> $masterList

    # send message
    mail -s "new file $file uploaded" you@youremailid.com
  fi
done

Save this to a file named /root/monitor-uploads.sh
Make it executable:

chmod +x /root/monitor-uploads.sh

NOTE: This code is untested.

Your cronjob could be stored as the following file:

/etc/cron.d/uploads

and could contain:

*/1 * * * * root /root/monitor-uploads.sh > /tmp/monitor-uploads.log 2>&1

atreyu, your script will work of course.
But may I suggest the use of inotify for this?

e.g. incrond can watch the directoy for changes and trigger actions.

That of course is a brilliant suggestion...
