Using Built-in and Group Aliases
Many CLI commands have an alias, useful for quickly entering an often-used command.
The alias command supports the creation of custom aliases.
For example, the following command halts the current group:
dfocus g dhalt
Using an abbreviation is easier. The following command does the same thing:
f g h
Some frequently used commands for which an alias may come in handy include dbreak (b), ddown (d), dfocus (f), dgo (g), dlist (l), dnext (n), dprint (p), dstep (s), and dup (u).
The CLI also includes uppercase group versions of aliases for a number of commands, including all stepping commands. For example, the alias for dstep is s; in contrast, the alias for dfocus g dstep is S. The first command steps the process. The second steps the control group.
Group aliases differ from the group-level command that you type interactively, as follows:
They do not work if the current focus is a list. The g focus specifier modifies the current focus, and can only be applied if the focus contains just one term.They always act on the group, no matter what width is specified in the current focus. Therefore, dfocus t S does a step-group command.
