Good morning !! I'm creating a script and I need when I make a grep on a line and can not find it, it returns the parameter I looked for!
grep "192.0.0.1" /file.txt
In the .txt file it does not have the string "192.0.0.1" I want it to return "192.0.0.1" for me to save to another file, I am not able to use diff because the default on each line in the file is different.
Thank you
I was able to solve this problem as follows!
grep -v '^#' < arquivo.com.o.que.procuro | while read line2; do
valor=$(grep -c "$line2 " arquivo.onde.estou.procurando)
if [ $valor -eq 0 ]; then
echo $line2 >> arquivo.onde.vai.salvar.o.que.nao.encontrou
echo $line2 $valor "eh diferente"
fi
done
