Bash script separate logs from one pod to another - bash

Question

How can I separate the logs from one pod to another?
Below is what I worked on:
CrashLoopBackOff=`for i in $(kubectl get po -n namespace | grep CrashLoopBackOff | awk '{print $1}'); do echo $i; done`
for y in $CrashLoopBackOff; do
k8s_logs=`kubectl logs $y -n namespace | tail -10` arr2+="$k8s_logs\n"
done
But the output is all together for 2 crashed pods or more pods and I cannot differentiate the logs from each pod. Any idea how can I put an echo or something between each pod log?

Please don't forget to give part of kubectl get po -n namespace's output for people to know what kind of data you are working on.
Also, the backquote (`) is used in the old-style command substitution, e.g. foo=`command` . The foo=$(command) syntax is recommended instead. Backslash handling inside $() is less surprising, and $() is easier to nest. See http://mywiki.wooledge.org/BashFAQ/082
See also https://mywiki.wooledge.org/BashFAQ/001 to learn how to read lines of input
The rest of your code is not even working, so here is working code based on my assumptions on what you tried to achieve:
arr2=()
while read -r crashing_pod _; do
while IFS= read -r line; do
arr2+=("$crashing_pod: $line")
# arr2+=("$line")
done < <(kubectl logs "$crashing_pod" -n namespace | tail -10)
# arr2+=('' "end of $crashing_pod 's logs" '')
done < <(kubectl get po -n namespace | grep CrashLoopBackOff)
printf %s\\n "${arr2[#]}"
You'll see I have prepended each line with the pod name, but you can use the two commented outlines instead if you'd rather have a separator like requested.
