Issue deleting all lines (having a specific string) in a file
I'm trying to create a script.

There are 2 files - fileA.log & fileB.log
fileA.log has the below data :
aaaa
cccc
eeee

fileB.log has the below data :
cjahdskjah aaaa xyz
jhaskjdhas bbbb abc
ajdhjkh cccc abc
cjahdskjah dddd xyz
jhaskjdhas eeee abc

I need to read each line from fileA.log, check fileB.log for that string and delete the line from fileB.log, if that string exists

Finally the file fileB.log should have the below data :

jhaskjdhas bbbb abc
cjahdskjah dddd xyz

Below is the script that I've used :

Code:
File_A=/tmp/fileA.log
File_B=/tmp/fileB.log
while read line
        do
        sed -i "/\b$FileA\b/d" $File_B
done <$File_A

But unfortunately, it is deleting all the lines.

Please let me know what's wrong with my script.
