Linux Alternative to tail -n -0 -F for monitoring live log file

Hello,

I have been working on script which need to generate an alert based upon live logs. If string is found then an alert mail must triggered.

tail -n -0 -F works fine to redirect the each latest line from live logs file to grep a pattern for matching but it seems to be not working on SunOS 5.10 Generic_147441-19 i86pc i386 i86pc

Can anyone have a good alternative or any suggestion on this?Smilie

Code:
tail -n -0 -F $LOG_DIR"/COMMON-ERROR.log" | while read myline; do
ERROR_CODE=$(echo $myline | awk -F ' ' '{for (i=1;i<=NF;i++){if($i ~ "^[1-1]" && length($i)==6){print $i}}}')
:
:
done

Thanks,
Ketan R
