killing tail --pid=???

Howdy!

I am working on a project where I know nothing about what I'm doing as usual.

So here goes..

I have a script the runs from another like this

Code:

$SCRIPTDIR/oblog Overwrite &
echo $! > $PIDDIR/oblog.pid

the script is like this

Code:

if [ "$1" = "Overwrite" ]; then
tail -f $DATADIR/$FNAME.raw |sed -e 's/^~...//' |grep -f $GREPFILE > $DATADIR/$FNAME.ob

I can close the script down like this

Code:

kill -1 `cat $PIDDIR/oblog.pid`

tail, sed, and grep are still running
I want to kill off tail so sed and grep will finish

Maybe some use of --pid with tail, I would need to pipe something to it to do that, not sure
some other signal maybe?
any ideas?

thanks,

The only think I can think of off hand is to write a kill script that will kill the tail. Pass in the oblog PID

Code:

#!/bin/sh

IFS='
'

for i in `ps -ef | grep tail`; do
   ID=`echo $i | awk ' { print $3 } '`
   if [ $ID -eq $1 ]; then
      echo kill  `echo $i | awk ' { print $2 } '`
   fi
done

Remove the echo when you are ready to kill.
