shell - Can't grep file correctly -


मेरे पास बहुत सरल सिंटैक्स वाला फ़ाइल है: 

  cat / tmp / test ARCH = "" प्रेटकैंक-बी | Awk '/ ^ नाम: / {प्रिंट $ 2}'   
 मैंने इसे grep करने का प्रयास किया:  
  cat / tmp / test | Grep "prtconf -b | awk '/ ^ नाम: / {प्रिंट $ 2" ARCH = "" prtconf -b | Awk '/ ^ नाम: / {प्रिंट $ 2}'   
 चलिए थोड़ी देर के लिए grep स्ट्रिंग बनाते हैं, अंत में जोड़ें}:  
  cat / tmp / परीक्षण | Grep "prtconf -b | awk" / ^ नाम: / {प्रिंट $ 2 "}   
 कुछ भी नहीं मिला  
 जब मैं लाइन grep के अंत में जोड़ता हूं  
 ओएस सोलारिस 10 यू 11   
 
 
  $ 2  कमांड-लाइन पैरामीटर को संदर्भित करता है, इसलिए  यहां यह खाली अक्षर को एक पट्टी में स्थानांतरित करेगा  तो आपको  $  स्लैश से  \ $   
  cat / tmp / test से बचने की आवश्यकता है I Grep "prtconf -b | awk" / ^ नाम: / {print \ $ 2} "  
 को जोड़ने के बिना }  आपकी पट्टी में यह काम कर रहा था क्योंकि यह मिलान था वास्तविक कोड के रूप में  prtconf -b | awk '/ ^ नाम: / {प्रिंट  अपने इनपुट के लिए लेकिन अगर आप अपने कोड में }  जोड़ते हैं तो यह  prtconf -b से मेल करने का प्रयास करेगा। Awk '/ ^ नाम: / {print}  (जो आपकी फ़ाइल में नहीं है इसलिए यह आउटपुट प्रदर्शित नहीं करेगा।)

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
