linux - How to pass command output as several arguments to another command -

-

इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 2 जवाब

मेरे पास एक कमांड है जो उत्पादन करता है इस तरह से आउटपुट: 

  $ ./command1 word1 word2 word3

मैं इन तीनों शब्दों को तर्क के रूप में किसी अन्य कमांड को इस तरह से पारित करना चाहता हूं:

< Div class = "post-text" itemprop = "text">

बस एक अनक्ॉटेड कमांड प्रतिस्थापन का उपयोग करें: 

  $ ./command2 $ (./ command1)

हालांकि, यह पाथनाम पीढ़ी के लिए command1 के आउटपुट को भी पेश करता है, इसलिए यदि आउटपुट में कुछ ली हो सकती है के *। Txt , आप जोखिम को जोखिम में डालते हैं कि इसे कमांड 2 के पास करने से पहले कई शब्दों में विस्तारित किया जा रहा है। उस स्थिति में, आपको 

  $ arg1 arg2 arg3 & lt; & lt; & lt; "$ (./ command1)" $ ./command2 "$ arg1" "$ arg2" "$ arg3"

या

<पूर्व> $ read -a आर्ग्स & lt; & lt; & lt; "$ (./ command1)" $ ./command2 "$ {args [@]}" को आउटपुट को पाथनाम पीढ़ी के अधीन किए बिना 3 शब्दों में विभाजित करने के लिए।

यह काम नहीं करेगा अगर कमांड 1 के आउटपुट की तरह दिखता है 

  "word1a word1b" word2

और आप दो तर्कों, word1a word1b और word2 से कमांड 2 पारित करने में सक्षम होने की अपेक्षा करते हैं, लेकिन यह प्राप्त करने के लिए अधिक आवश्यकता के लिए पर्याप्त रूप से मुश्किल है विवरण के बारे में जानकारी के लिए कि कमांड 1 सही समाधान प्रदान करने के लिए आउटपुट कर सकता है।

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
