Hi!
I need to monitor multiple files and filter lines that contain a word
One approach is to use pipe. The command tail with its output coupled with the
grep command for each file monitored. Each pipe would write in a single file as
background processes
Then use another tail monitoring the single file that is the union of the other
files filtered. Here is my code.
[code]
rm -f /tmp/tailLogfile
#File log list
for v in `ls /var/scp/log/*child*.log`
do
echo Monitoring $v
tail -100f $v | egrep -e "MessageIN" >>/tmp/tailLogfile 2>&1 &
done
echo Monitoring "/tmp/tailLogfile"
tail -100f /tmp/tailLogfile
[/code]
When running, the last tail is my monitor. To exit should press Ctrl + C.
My problem is that I can not kill the tail and grep processes that run in the
background once it finishes the script. And the worst thing is that is
generated new instances every time I run the script.
If i use $! to capture the last pid of background process on the line
[code]
tail -100f $v | egrep -e "MessageIN" >>/tmp/tailLogfile 2>&1 &
[/code]
$! capture only grep pid but not tail pid to kill them
Anyone know of any way to solve this?
