bash - Multi line tab separated file to comma separated -

-

I have a large file that is different tabs The biggest problem is that I have to import the data into the database but some columns There are multi lines that are causing some problems, what I would like to do to convert the file, which converts the file into a different file than the right comma. Here is an example of a file (I will change the option of tab with pipe.): 

  1 | Some text | Second lesson. 12 | Bigger bigger text with lots of data and many lines and commas. 34 34 2 | Some text | Another text || There are basically two rows of data in the above example, what I would like to do:  
 < Code> "1", "some text", "other text", "12", "bigger bigger text with lots of data and many lines" 34 "," 34 "," 34 "" 2 "," some Text "," Other text "," ", and another big big text with many letters in the tab", "33", "25"   
 I can see Every full line of data (one With fie line column) is terminated by ^ M $, it looks like:  
  1 | Some text | Another lesson. 12 | Bigger bigger text with lots of data and multiple lines and commas. 34 34 ^ M $ 2 | Some text | Second text || A big big big text with many letters, and tabs. 33 | 25 ^ M $    
 
 
 This is really difficult, and it executes the correct sequence of substitutions Depends on doing Looks like the following is done (at least on your given example):  
  "Attach non-multi-line lines with citations. G / \ t / s / ^ \ | \ (\ R \) $ / "\ 1 / g" Undo the quotation that ends / ends before the start of a multiline. V / \ t / -1s / "$ //: v / \ t / + 1s / ^ "//" undo an incomplete (i.e. no ^ m) starting bid after the previous record. : G / \ t / -1s / \ r \ @ & lt ;! \ N \ zs "//" Change the tab with quotation and commas:% S / \ t / "," / g "Finally, remove the ^ M-off-record marker.% S / \ r $ //

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] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
