git - in zsh, how do I do a conditional on the exit status of a program? -


मुझे कुछ ऐसा करने के लिए wnat: 

  अगर [[git स्थिति & amp; & gt; / Dev / null]]; फिर "एक जीआईटी रेपो" गूंज; Else गूंज "एक git repo नहीं है"; फाई

को छोड़कर मुझे पता नहीं है कि कैसे बाहर की स्थिति पर जाँच करने के लिए। मैं इसे कैसे ठीक करूं?

धन्यवाद

का प्रयोग करें $? < / कोड>, इसमें अंतिम कमांड रिटर्न कोड होता है

संपादित करें: सटीक उदाहरण: 

  git स्थिति & gt; & amp; / Dev / null अगर [$? -ई 0 0]; फिर "जीआईटी स्थिति सफलतापूर्वक समाप्त हो गई" एको गूंजती "गिट स्थिति त्रुटि कोड से बाहर निकली" फ़िक्स

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?
