fgt runs any command for you and exits with exitcode 1 when the child process sent anythingto stdout or stderr
go get github.com/GeertJohan/fgt
Some examples:
fgt true will return successfully
fgt false will return with exitcode 1
fgt echo hi will return with exitcode 1 (even though echo returned with exitcode 0)
fgt gofmt -l <yourpackage> will return with exitcode 1 when gofmt indicates something must be formatted diferently
This command was created to make sure jenkins will complain when gofmt needs something formatted.
