Questions tagged [subcommand]

Use this tag for questions related to subcommands, i.e. commands inside a routine.

Subcommands make it possible for you to group related command line functionality under one root command.

Examples of subcommands are install in apt-get install and push in git push.

Users tend to use this tag for questions related to existing subcommands, or subcommands that are an artifact of the users itselves. Last but not least, questions that handle subcommand arguments, for example in a Python program, are also suitable for this tag.
