Hi, Douglas. I got it working last night after some hints from Tony. Here is my
working version:
----- begin script ----
#!/bin/bash
#
# Notify the admin if a directory's contents has changed.
#
# The directory to monitor.
watchdir='/var/spool/voice/incoming'
#watchdir='/home/jb/Mail/incoming/jbinpg'
#watchdir='/tmp'
# Who gets notified of changes. This may be a
# comma-delimited list, but no spaces.
recipient='[EMAIL PROTECTED]'
# The file that holds an md5sum of the directory
# listing, as of the last time it was changed.
sumfile='/home/jb/sumfile'
## End of settings ##
## Now we compare old sumfile of watchdir to new sumfile and if different ##
## overwrite old with new ##
# Get the previous md5sum of the directory listing.
#olddirsum=`cat $sumfile`
olddirsum=$(cat $sumfile)
# Get the current md5sum of the directory listing. Use the
# --full-time option to avoid errors based on ls changing the
# displayed date format based on the age of the file.
#newdirsum=`ls --full-time $watchdir | md5sum`
newdirsum=$(ls --full-time $watchdir | md5sum)
# Compare the previous md5sum to the current md5sum.
if [ "$newdirsum" != "$olddirsum" ]; then
# Get the process ID and scriptname and use them to
# generate a tempfile name. This method is not guaranteed
# unique, but it should be Good Enough.
pid=$$
scriptname=$(basename $0)
mailfile=/tmp/$scriptname.mailfile.$pid
# Check each file in $watchdir to see if it was created or changed
# since the last md5sum was generated.
for file in $(ls $watchdir); do
if [ $file -nt $sumfile ]; then
ls --full-time $file >> $mailfile
## Now mail a notification message to the recipients list ##
mail -s 'New voicemail message detected' $recipient < $mailfile
## then delete mailfile
rm $mailfile
fi
done
fi
# Finally, update the summary file with the current md5sum.
echo "$newdirsum" > "$sumfile"
------ end script ------
I have it monitoring my dump directory for my voicemail app, VOCP (shameless plug:
awesomely useful set of perl apps at http://www.vocpsystems.com). Naturally, it can
be tailored to watch anything you want.
If you are having trouble, I would suggest commenting out the "rm $mailfile" until you
know it is being written.
