bash - Use variable inside double quotes inside single quotes in sed -

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

  • 4 जवाब

मैं एक के लिए खोज करना चाहता हूँ स्ट्रिंग एक स्थितिबद्ध पैरामीटर द्वारा दिए गए दोहरे उद्धरण में संलग्न है। यह मैंने किया है: 

  #! / Bin / bash FOO = $ 0 sed -i / "$ {FOO}" / बार / मी file.txt

न तो "$ FOO" और \ "a $ {FOO} \" / काम नहीं करें

मुझे पता है कि चर के विस्तार के लिए, आपको पूरे रिजक्स को दोहरे उद्धरण () में जोड़ना होगा बात यह है कि जिस स्ट्रिंग के लिए मैं खोज रहा हूं वह भी दोहरे उद्धरण में संलग्न है, यही कारण है कि मैंने संपूर्ण रीगेक्स को सिंगल कोट्स में रखा था। मैंने इसे दोहरे उद्धरण चिह्नों में शामिल करने और दोहरे उद्धरण से बचने की कोशिश की, लेकिन यह काम नहीं कर रहा था।

P> sed कमांड के रूप में sed कमांड का प्रयोग करें

sed -i "s / \" $ {FOO} \ "/ bar / m" file.txt

टेस्ट:

<पूर्व> $ इको $ बी हैलो $ इको \ "हैलो \" | Sed "s / \" $ b \ "/ asdf /" asdf

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...
