linux - filter out content between two files


I have two files





I am expecting output to be:


Actual output:


Here's the code I had worked till now

while read condition
if [[ $line = $condition ]] ; then
echo "$line";
done < condition.txt

while read line
func $line
done < log.txt

Try using grep:

$ grep -v -f conditions.txt logs.txt

From the man page for GNU grep:

-v, --invert-match
          Invert the sense of matching, to select non-matching lines.

-f FILE, --file=FILE
          Obtain patterns from FILE, one per line.  If this option is used multiple times or is combined with the -e (--regexp)  option,  search  for  all  patterns
          given.  The empty file contains zero patterns, and therefore matches nothing.

If you don't feel like re-inventing wheels ...

grep -vf conditions.txt logs.txt
