Shell Programming and Scripting

Hello,

I'm trying to select, or well put the PID that is given by fuser to a var.. It has a wierd format and I somehow can't get it working, any awk/sed experts about?

Code:

PID=`fuser $file | awk/sed....?`
if [ "$PID" != "" ]; then
kill $PID
fi

Greetings and thanks for all your awesome help in advance!

Code:

kill $(fuser $file)

just works, at least on Solaris which created the fuser command. Don't be fooled by fuser output format. It splits its output between stdout and stderr.

Further to jlliagre. There is much variation in "fuser" behaviour.

For a sample file or device which is open for write by more than one process, please post:

Code:

fuser filename 1>/dev/null
fuser filename 2>/dev/null

Concidentally on many O/S /dev/null is open by multiple processes. We could run fuser on this device to get some test output.
Obviously this is not a good device to test a kill script.

A number of OS also support the -k option to terminate process found. Would that be neater?

Code:

# fuser -k $target_file

It can be dangerous thought to automate killing processes. I have managed to kill process 1 on one occassion. I had trace running to the screen in advance, then after issuing the kill -9 1, the console went very quiet and the phone starting ringing.

That would be

Code:

fuser -k -s TERM $file

to avoid SIGKILL.
