Bash compound commands

The main part of Bash's syntax are the so-called compound commands. They're called like that because they use "real" commands (simple commands or lists) and knit some intelligence around them. That is what the essential "Bash language" is made of.

Command grouping

grouping: command grouping
grouping again: command grouping in a subshell

Conditional reactions

Note that conditionals can also be scripted using list, which are syntax elements, not commands.

the "new" test command: conditional expression
if-clause: conditional branching
case statement: pattern-based branching

Loops

Misc

math: arithmetic evaluation
menus: user selections
