  • Why are you looping on $loop2 -eq 0 when it looks like you want $j -lt 11? Commented Jan 15, 2018 at 4:06
  • It'll be an infinite loop, but I want to be able to terminate it when the parent loops. I was just using $loop2 -eq 0 in hopes that changing the value of the variable would end the loop. But that didn't really pan out. Obviously this script is a simplification. My $j won't necessarily be 10 Commented Jan 15, 2018 at 4:11
  • Your nested loop runs in a subshell, so no change in variables in the outer loop will affect it. You'll have use something else, like a file, to tell the inner loop that the outer loop has changed. Commented Jan 15, 2018 at 4:12
  • The value of $j isn't really relevant to what I'm trying to do. I'm just trying to get the basic mechanics working. I want to have nested loops, and I want to be able to kill the nested loop and start it over when the parent loops. Commented Jan 15, 2018 at 4:13
  • I could use a file, but it seems a bit clunky. Is that the only option? I was also hoping "break" would help me, but it only works in the opposite scenario. (Killing the parent loop from within the nested loop.) One thing I noticed is that each "while" loop creates a new /bin/bash process with a unique PID. If there's a way to pinpoint the PID of the nested "while" loop, I could just kill the process at the end of the parent loop. But I couldn't figure out how to pinpoint it.
