String Manipulation in Groovy

Assuming:

def text = "arn:aws:ecs:us-west-2:496712345678:task-definition/test:2" + "\n" + "arn:aws:ecs:us-west-2:496712345678:task-definition/test:3"

Try :

text.split("\n").collect {c -> c.split("/").last()}

This prints a list of [test:2, test:3]

If you want it in one line and not in an list, use:

text.split("\n").collect {c -> c.split("/").last()}.join(",")

This prints: test:2,test:3

Update

Due to OP's comment, the answer after all should look something like:

def p = 'aws ecs list-task-definitions --family-prefix test'.execute() | 'jq .taskDefinitionArns[]'.execute()
p.waitFor()
def text =  p.text
println text.split("\n").collect {c -> c.split("/").last()}

def p = 'aws ecs list-task-definitions --family-prefix test'.execute() | 'jq .taskDefinitionArns[]'.execute() p.split("\n").collect {c -> c.split("/").last()}.join(",") but I am getting the following error Caught: groovy.lang.MissingMethodException: No signature of method: java.lang.UNIXProcess.split() is applicable for argument types: (String) values: [ ]

In the question there is p.waitFor() and p.text to get a text. save it in variable and then try the snippet I've provided in the answer

I've updated the answer in any case

It worked !!! I have got the following result [test:2", test:3"] but I want it like test2 test3 below each other

Then use: text.split("\n").collect {c -> c.split("/").last()}.join("\n")
