Hi, I'm trying to create a sequence of Karaf commands I can alias to detect
if a child instance with a particular name exists but am running into some
trouble because if it doesn't exist the command returns null and I can't
figure out how to detect it.
The statement I'm trying to execute is:
i = (instance:list | grep child)
I'm trying to then use an if statement to check if $i is nor empty (which I
can't figure out either.) If the child instance doesn't exist, then $i =
null which causes issues if I tried to say:
if {$i isEmpty} {
...
}
Is there a better way to do this in Karaf 3.0.3 out of the box?
Thanks,
Ryan
