Scripting Commands

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

The Shell commands supports the following advanced constructs for scripting:

Arrays
Running multiple commands at once
Pipes
Command grouping
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"

Running Multiple Commands at Once

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

admin@localhost:/> cd /TEA;ls
Access
Agents
Search
Server
Shell
Tea Machines
Tea Repository
Tea Solutions
Types
Views

Pipes

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

admin@localhost:> ls /TEA/Types | grep a
tea:1.0.0

Command Grouping

Multiple commands can be grouped using parenthesis, '( ' and ') ' to specify the order of execution.

(echo a | capture) | capture

Closures

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

admin@localhost:> each { ls } {show info $it}
Name:Access
Type:tea:1.0.0:access
Config:
{"activeUsers":[]}

Name:Agents
Type:tea:1.0.0:agents

Name:Search
Type:tea:1.0.0:search

Name:Server
Type:tea:1.0.0:server
Config:
{"version":"1","homeLocation":"..\:\\tea"}

Name:Shell
Type:tea:1.0.0:ShellType
Status:RUNNING
Config:
{"host":"localhost","port":2222,"path":"..\\internal\\nodes\\node1\\work\\cf
\\bcd28823-db70-48be-84d5-6c2295667295\\work\\hostkey.ser"}

Name:Tea Machines
Type:tea:1.0.0:teaMachines

Name:Tea Repository
Type:tea:1.0.0:teaRepository

Name:Tea Solutions
Type:tea:1.0.0:solutions

Name:Types
Type:tea:1.0.0:agent_types_group

Name:Views
Type:tea:1.0.0:views


admin@localhost:>

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"}'
