$ के अनुसार? मूल्य जो 1 है, यह लूप को तोड़ना चाहिए, लेकिन यह नहीं है।

क्या कोई मुझे बता सकता है कि इसके साथ समस्या क्या है?

आप $? परीक्षण कर रहे हैं पिछली पंक्ति पर गूंज कमांड की स्थिति है।

यदि आप इसे एको करना चाहते हैं और फिर इसे जांचते हैं, तो इसे एक चर में सहेजें: 

  / usr / bin / mysql ... status = $? "$ Status" को प्रतिध्वनित करें अगर [$ status -q0]; तब ... fi
