bash - awk/sed: How to do a recursive find/replace of a string? -

-

मैं कैसे की हर घटना को ढूंढ और बदलूंगा: 

  subdomainA.example.com <  / home / www के अंतर्गत प्रत्येक पाठ फ़ाइल में / code>  
  
  उपडोमेन B.example.com  
 
 के साथ /  डायरेक्टरी ट्री (रिकर्सिव ढूंढें / प्रतिस्थापित)।

ध्यान दें : इस कमांड को जीआईटी रेपो सहित .git में बदलकर, अपने जीआईटी इंडेक्स को भ्रष्ट कर सकता है, पर इस कमांड को न चलाएं। 

  find / home / www -type f -print0 | Xargs -0 sed -i 's / सबडोमेन ए \ .example \ .com / subdomainB.example.com / g'

से आदमी खोज :

-print0 (जीएनयू केवल खोजने के लिए) पादनाम नाम के बीच आउटपुट सीमांकक के रूप में रिक्त स्थान के बजाय रिक्त वर्ण (\ 0) का उपयोग करने के लिए कहता है यह एक सुरक्षित विकल्प है यदि आप फ़ाइलों में खाली या अन्य विशेष वर्ण शामिल कर सकते हैं यह -print0 तर्क का उपयोग करने के लिए सिफारिश की जाती है यदि आप -exec कमांड या एक्सरग्राज का इस्तेमाल करते हैं (xargs में -0 तर्क की आवश्यकता है।)।

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
