unix - Use grep in Mac Terminal -


मैं निम्नलिखित कमांड के साथ मैक में टर्मिनल का उपयोग करता हूं: 

  df -lak | Grep फ़ाइल || डिस्क02

क्या मैं इस स्क्रिप्ट का उपयोग डीएफ कमांड (डिस्क स्पेस) के शीर्ष को पाने के लिए करना चाहता हूँ और केवल डिस्क 2 के साथ लाइन मुझे लगता है कि '|' Grep के रूप में या तर्क में एक चार है हालांकि, जब से मैं टर्मिनल में grep का उपयोग कर रहा हूं, चार '|' इसका अर्थ है पाइप इसलिए मैंने '||' का उपयोग करने की कोशिश की पाइपिंग से बचने के लिए, लेकिन यह जो मैं चाहता हूँ वह नहीं मिलता। केवल "फाइल" के साथ शीर्ष लेख वापस आ गया है।

निश्चित नहीं है कि कैसे मैं टर्मिनल में इस स्क्रिप्ट कमांड का उपयोग कर सकता हूं?

awk का उपयोग करें 

  df -lak | Awk 'एनआर == 1 || / Disk02 / '

या 

  df -lak | Grep -E "फ़ाइल | disk02"

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
