Working with the command line
We've already seen some of what outcome
CLI tooling can do for us. In the past few chapters we've used commands like new
and run
. We never got to explore them in more detail though. That's what we will focus on in this chapter. We will also introduce some totally new and exciting functionality.
When in doubt, use --help
As with most command line tools, the --help
flag, also available in it's shorter form -h
, is your friend.
Additional help is available for each of the subcommands, not only the top level of the program. When in doubt, use the --help
option to get a rundown of required arguments, as well as available options and flags, for any of the program subcommands.
