# 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](../../syntax/basicgrammar.md#simple_commands) or
[lists](../../syntax/basicgrammar.md#lists)) and knit some intelligence around
them. That is what the essential "Bash language" is made of.

## Command grouping

-   grouping: [command grouping](grouping_plain.md)
-   grouping again: [command grouping in a subshell](grouping_subshell.md)

## Conditional reactions

Note that conditionals can also be scripted using
[list](../../syntax/basicgrammar.md#lists), which are syntax elements, not
commands.

-   the "new" test command: [conditional
    expression](conditional_expression.md)
-   if-clause: [conditional branching](if_clause.md)
-   case statement: [pattern-based branching](case.md)

## Loops

-   [classic for-loop](classic_for.md)
-   [C-style for-loop](c_for.md)
-   [while loop](while_loop.md)
-   [until loop](until_loop.md)

## Misc

-   math: [arithmetic evaluation](arithmetic_eval.md)
-   menus: [user selections](user_select.md)
