list of files NOT in use by process

Question

How can I exclude the output of lsof -c <processname> /path/ from a list of files in /path/ for example find /path/ -type f

I was thinking something like this:

find /home/ncr/downloads -type f | egrep "lsof -c rtorrent /home/ncr/downloads"

(replace quotes with backticks) but that doesn't seem to work...

I'd actually like to know this for other purposes as well. What is the best way to do this?

Answer 1

you could try somethign like this:

#! /bin/ksh

find /var/log/httpd -type f | while read line
do
    a=`lsof $line`

    if [[ $a == "" ]] ; then
            echo $line "not being used"
    else
            echo $line "being used"
    fi
done
