Code:
ls | grep -vf - /root/dustbin.ini | sed 's/.*/^&$/' > removed.txt

I then tried appending it to
Code:
ls | grep -vf - /root/dustbin.ini | sed 's/.*/^&$/g' > removed.txt



Then no errors were detected but it did not delete any file locations at all.

It left both:
Code:
/root/helloworld 
/root/hello


Think I should be editting it to perhaps not have an s at start but have a d at end perhaps? Just about to try that out.

You don't need the 'g' since you replace the whole line, the replacement should occure only once (so no need of 'g' option)

Show me how look the corresponding entries of these 2 files in your FileLocation.txt

What convention/rule did you choose to "make the name uniq" in dustbin.ini ?

they just are
Code:
"/root/hello
/root/helloworld"

in FileLocations.txt.


Not sure if I made them unique in dustbin.ini, I just used the code
Code:
ls > /root/dustbin.ini

I first changed to the directory dustbin of course.
Code:

Edit again: Oh and I have the s at start of code just removed it for trying something but its actually there.

Why don't you just :

Code:
exec 3</root/FileLocations.txt
while read -u3 a
do rm -i $a
[[ -f "$a" ]] && echo "$a" >>/anywhere/remaining.txt
done
exec 3<&-
cat /anywhere/remaining.txt >/root/FileLocations.txt
rm /anywhere/remaining.txt

This code assume /root/FileLocations.txt contains absolute filenames (just like in your example)

Well i got it working now by editting some stuff about I think it was not deleting because of the ^ so it expected it to be at the start but really what was always going to be infront of it was a slash so I changed the ^ to \ / and it worked Smilie


Will try that other code to see how it goes as well though, and if you want can let you know how it goes?

No you got it wrong : you need that ^
try your script with the list the 6 files below:
Code:
/root/helloworld
/root/world
/root/hello
/roothello
/rootworld
/roothelloworld

.... you see what i mean ? Smilie

The problem with doing that is that it tries to delete them from

Code:
 
/root/helloworld instead of /dustbin/helloworld

Also i get the problem if I change it that it puts in the FileLocations.txt

Code:
 
hello
world

instead of
Code:
 
/root/hello
/root/world
