I've been trying and getting frustrated :-( How do I add another instance of grep. For example, how do I add another one in the same line.

I have this grep -c 'state:unreachable', but I need to add 'state:invalid'. To get a count of the "invalids"

The problem is that I don't know where you want the output. Anyway, maybe something like this:

Code:

awk 'BEGIN {
         unreachable_count = 0
         invalid_count = 0
     }
     /state:unreachable/ {
         unreachable_count++
     }
     /state:invalid/ {
         invalid_count++
     }
     END {
         print "Invalid Count: " invalid_count
         print "Unreachable Count: " unreachable_count
     }'

     }
     /state:invalid/ {
         invalid_count++
     }
     END {
         print "Invalid Count: " invalid_count
         print "Unreachable Count: " unreachable_count
     }'

The output can display on the screen. I just need a count to appear.

         print "Unreachable Count: " unreachable_count
     }'

I tried that, it worked fine in its form. I've been trying to code it in such a way to have both counts = a single numeric output. Meaning "invalid" + "unreachable" = 5 (as an example)

How about this:

Code:

print invalid_count + unreachable_count

?
