monitor new logs

http://www.unix.com – I would like to monitor logfile for specific keyword and send email once detected. I'm trying out the code here, the script is scheduled to run every minute. Everytime it runs, the same log will be detected and send email. Anyway it can be improved to detect only new logs? tail -f /logfile | while read line ; do if [[ `echo $line | grep "keyword"` ]] then a="`echo $line | grep "keyword"`" echo $a "detected" email alert fi done (HowTos)

Greetings.

I have a script that purges files from a folder and I would like a record (log file) of what files were purged.

I wrote the following snippet and it works when executing it from the command line:

Code: LOGFILE="/path/to/logfiles/purge-folder.log" echo "`date +%Y-%m-%d_%H:%M:%S` - Script started." >> ${LOGFILE} for file in "/path/to/folder/*.txt&quo
