I am a C++ programmer and little knowledge of bash ;)

I have $output string in format

Command line asked for 29 of 639 tests
Of those: 0 Skipped, 5 Failed, 0 Warned, 24 Passed

I wanted to extract the integer before Failed and assign it to bash variable (in this case 5)
How do i do this in bash script. I want to make sure the value is "0" which means no test failed
