# Scripting Commands

You can use advanced scripting constructs to combine multiple commands and write complex scripts.

The Shell commands support the following advanced constructs for scripting:

- Arrays
- Running multiple commands at once
- Pipes
- Closures
- Json ComplexType

## Arrays

Arrays can be passed as arguments to some commands. For example, the `echo` command takes an array of arguments passed to it and displays them at the command prompt.

    echo [ 'a' 'b' 'c']
    [a,b,c]

Note: In the web UI, use commas as separators. For example, ['a', 'b', 'c']. In the shell UI, do not use commas as separators. For example, ['a' 'b' 'c'] .

## Running Multiple Commands at Once

Multiple commands can be run by separating them with a `';'` (semicolon).

    admin@localhost:/> cd /TEA;ls
    members
    agents
    users
    groups
    roles
    realms
    machines
    solutions

## Pipes

Output of one command can be piped to the input of another command using a '|'.

    admin@localhost:> ls TEA/members/Roles | grep a
    TEA_ADMIN
    Tomcat Admin
    Tomcat User

## Closures

Closures are functions which can be invoked with arguments. You can define and invoke the functions at run time. Curly braces, '{ ' and '} ' are used to enclose a closure definition.

    admin@localhost:/TEA> each {ls}{show info $it}
    Name:TEA
    Type:tea:2.1:TEA
    Status:Running

    Name:Agents
    Type:tea:2.1:agents

    Name:Users
    Type:tea:2.1:users

    Name:Groups
    Type:tea:2.1:groups

    Name:Roles
    Type:tea:2.1:roles

    Name:Realms
    Type:tea:2.1:realms

    Name:Machines
    Type:tea:2.1:teaMachines

    Name:Solutions
    Type:tea:2.1:solutions

## Json ComplexType

If the definition of TeaParam in a TeaOperation is a user-defined object, ensure that you use a String of the type: Json complexType.

    '{"strA":"aa","strB":"bb"}'

Note: Use single quotation marks to wrap the JSON input in the single command mode. In the interactive mode, do not use quotation marks.
