regex - Match exact word with awk on Mac OS X -

-

Mac OS X पर awk का उपयोग करने का प्रयास करें। उदाहरण: 

  $ echo "abc स्टॉक डीईएफ "| Awk / stock / abc स्टॉक def $ गूंज "एबीसी स्टॉकहोल्डर def" | Awk / stock / abc स्टॉकहोल्डर डीएफ़

मुझे परेशानी हो रही है जब मैं एक शब्द के साथ सटीक मिलान करने की कोशिश करता हूं। उदाहरण के लिए, मैं उपरोक्त उदाहरण में स्टॉकहोल्डर के बजाय स्टॉक से मेल करना चाहता हूं। मैंने \ & lt; , \ & gt; , \ b , \ y के साथ प्रयास किया। हालांकि, सभी ने मुझे उम्मीद के परिणाम नहीं दिए।

धन्यवाद

अगर यह हमेशा दूसरी स्थिति में है, तो आप इसका उपयोग कर सकते हैं: 

  awk '$ 2 == "स्टॉक"'

अगर यह किसी भी स्थिति में हो सकता है, तो इसका उपयोग करें: 

  Awk '{for (i = 1; i & lt; = nf; i ++) अगर ($ i == "स्टॉक") {print; अगले}} '

उदाहरण देखें:

<पूर्व> $ गूंज "एबीसी शेयर स्टॉक डीईएफ़" | Awk '{for (i = 1; i & lt; = nf; i ++) अगर ($ i == "स्टॉक") {print; अगले}} 'एबीसी स्टॉक स्टॉक def $ गूंज "एबीसी स्टॉक डीईएफ़" | Awk '{for (i = 1; i & lt; = nf; i ++) अगर ($ i == "स्टॉक") {print; अगले}} '$

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
