Hi moxy,

i'm not sure if its what exactly you want but try it, then tell us if it works or not, i couldnt test my code:

Code:
occ=`grep -c "string" logfile`

num_of_occ=`awk -v pattern="string" -v last="$occ" 
'$0~pattern{i++} i==last{print NR;exit}' logfile`

sleep 900

occ_=`grep -c "string" logfile`

num_of_last_occ=`awk -v pattern="string" -v lastocc="$occ_2" 
'$0~pattern{i++} i==lastocc{print NR;exit}' logfile`

if [ $num_of_occ -lt $num_of_last_occ ]; then mailx -s "WARNING!" admin@123.com

Actually only "grep -c" could be enough too Smilie

Code:
occ=`grep -c "string" logfile`

sleep 900

occ_=`grep -c "string" logfile`

if [ occ -lt occ_ ]; then mailx -s "WARNING!" admin@123.com
