Bash: Build and execute command lines on the fly with "xargs"

xargs is a powerful bash tool that can take input from $STDIN and pass it to a given command. I.e. you can do the following:

Copy
$> cat tmp/parallel_cucumber_failures.log features/authentication.feature:33 features/backend/pages.feature:5 features/backend/pages.feature:60 $> cat tmp/parallel_cucumber_failures.log | xargs geordi cucumber # Running features > Only: features/authentication.feature:33 features/backend/pages.feature:5 features/backend/pages.feature:60 ...

Beside the linked article you might also be interested in reading An Opinionated Guide to xargs Archive .
