what is the code If I want to get output of all the lines in log except the lines with string “Type: Error”

Answer 1

cat logFile | grep -v "Type: Error"

With this, first, you’ll display to video your file, then you’ll use -v option that invert the matches and the trick is done!

For multiple string, you could do something like this

cat logFile | egrep -v '(firstString)|(secondString)|(thirdString)|...|(nString)'
