Finds a running CLion instance and takes multiple jstack traces at a specified interval. Changing the regex should allow for use in any Java process that can be uniquely identified via jps.

CLionTrace.sh

#!/bin/bash

traces=10
interval=5

jps -mv | while read -r line; do
    if [[ $line =~ ^([0-9]+).*clion.*$ ]]; then
        printf "CLion running with PID %s\n" ${BASH_REMATCH[1]}
        for ((i = 1; i <= $traces; i++)); do
            printf "%d... " $i
            jstack -l ${BASH_REMATCH[1]} > jstack-$i.txt
            if (("$i" < "$traces")); then
                sleep $interval
            fi
        done
        printf "\n"
        break
