Find`s placeholder {} sed from variable1 and put into variable2

Then i use this script

for line in "`cat fromDirs.txt`"; 
do 
   find "$line" -type f \( -name '*good*' -o -exec grep -F "(NODES_'TASK')" {} \; \) -exec cp {} /tmp/ \;; 
done

I get in folder /tmp only file names from where they are copied, but i need this filenames contains full paths from where they comes, im bored to trying fight with sed, please help

So i need just take each {} value and replace slash (/) with minus sign (-)

I trying many of variant but nothing good, this code do not work too

for line in "`cat fromDirs.txt`"; 
do 
   find "$line" -type f \( -name '*good*' -o -exec grep -F "(NODES_'TASK')" {} \; \) -exec cp {} /tmp/$(sed "s/\//-/g" <<< {}) \;;
done

file fromDirs.txt contains

/home/orders/
/etc/bin/school/

there are no output, just nothing haping, maybe beacause i use sh? i havent bash at all on system

I think the problem is in sed as it read placeholder {} as file instead of string, so if {} = /home/orders/good.php then sed open this file and change all slashes to minus sign, but i need to changeslashes only in filename so /home/orders/good.php -> -home-orders-good.php and then cp to /tmp/-home-orders-good.php

I guess you get problem since you double quote the output of the file.
Try change from:

for line in "`cat fromDirs.txt`";

to:

for line in `cat fromDirs.txt`;

or better (remove old and outdated back tics):

for line in $(cat fromDirs.txt);

best (use while to read the file):

#!/bin/bash
while read line
do
   find "$line" -type f \( -name '*good*' -o -exec grep -F "(NODES_'TASK')" {} \; \) -exec cp {} /tmp/$(sed "s/\//-/g" <<< {}) \;;
done < fromDirs.txt
