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}
