after peak#495, `s5cmd --help` started to panic: ``` panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x158798e] goroutine 1 [running]: github.com/peak/s5cmd/parallel.(*Manager).Close(...) /Users/boraberkesahin/Documents/s5cmd/parallel/parallel.go:65 github.com/peak/s5cmd/parallel.Close(...) /Users/boraberkesahin/Documents/s5cmd/parallel/global.go:16 github.com/peak/s5cmd/command.glob..func5(0x16af2c0?) /Users/boraberkesahin/Documents/s5cmd/command/app.go:177 +0x10e github.com/urfave/cli/v2.(*App).RunContext.func1() /Users/boraberkesahin/Documents/s5cmd/vendor/github.com/urfave/cli/v2/app.go:309 +0x35 github.com/urfave/cli/v2.(*App).RunContext(0x1bf3c20, {0x1857a30?, 0xc000030e80}, {0xc000020040, 0x2, 0x2}) /Users/boraberkesahin/Documents/s5cmd/vendor/github.com/urfave/cli/v2/app.go:321 +0xa5b github.com/peak/s5cmd/command.Main({0x1857a30, 0xc000030e80}, {0xc000020040, 0x2, 0x2}) /Users/boraberkesahin/Documents/s5cmd/command/app.go:235 +0xa6 main.main() /Users/boraberkesahin/Documents/s5cmd/main.go:23 +0x9b ``` This is caused by (this PR)[urfave/cli@a1c26d5] from urfave/cli. `app.After` is called before `app.Before` is called. Fix this bug by making nil checks.
