I have a string like:
arn:aws:ecs:us-east-1:123456789:task-definition/myservice:10
Is there anyway I can get the last value 10? I tried to get last character but forgot that this int value can increase and eventually becomes 2 characters.

Did you mean after the colon – Inian Jul 16 '19 at 06:01

`str='arn:aws:ecs:us-east-1:123456789:task-definition/myservice:10'; echo "${str: -2}"; echo "${str##*:}"` – Inian Jul 16 '19 at 06:02

Well, many ways, this one works, though is not elegant :)
echo "arn:aws:ecs:us-east-1:123456789:task-definition/myservice:10" | sed 's/.*://'
