newline

问题 Suppose I have a text file with records of the following form, where the FS is generally speaking a comma, and the RS is generally speaking a newline. However, the exception to this rule is that if a field is in quotes, it should treat the line breaks and commas as part of the field. "This field contains line breaks and is quoted but it should be treated as a single field",1,2,3,"another field" How can I use awk to parse such a file correctly, where I can still access $1,$2... , as I usually

问题 Which text editors (free or commercial) handle character encoding and Windows/Unix line breaks properly? 回答1: Here's a list of Text editors and their newline support. Also see this list and look at the Newline conversion field 回答2: I should think the vast majority do. Certainly Vim and Emacs will. 回答3: Notepad++ is free and handles this dandily. Not to mention it's quite handy for plenty of other text-editing tasks. 回答4: textpad does a good job. i like version 4.7 it is much nicer than 5.*

问题 I'm just starting python so am most likely just doing something stupid. I'm reading data off of a table and need to put them into columns in a txt file. I cannot convince my code to create a new line. Here is my code- file = open("test_m.rdb") table = open('table.txt', 'w+') trash = file.readline() trash = file.readline() data = file.readline() i = data.split() flux = i[2] observed = i[4] table.write(flux + " " + observed,) while 1: line = file.readline() i = line.split() try: flux = i[2]

问题 Given a literal string such as: Hello\n\n\n\n\n\n\n\n\n\n\n\nWorld I would like to reduce the repeated \n 's to a single \n . I'm using PHP, and been playing around with a bunch of different regex patterns. So here's a simple example of the code: $testRegex = '/(\\n){2,}/'; $test = 'Hello\n\n\n\n\n\n\n\n\nWorld'; $test2 = preg_replace($testRegex ,'\n',$test); echo "<hr/>test regex<hr/>".$test2; I'm new to PHP, not that new to regex, but it seems '\n' conforms to special rules. I'm still

问题 I am a newcomer to PS scripting. I have found that, generally speaking, PS adds a lot of newlines to output of its commands. I am giving below a couple of examples of what I found somewhat generalized about the (default?) output in PS commands. I am used to Unix-like output, where the generalized output has few to none of these lines (of course, nothing prevents a programmer from adding them). Is there a configurable way to reduce the amount of those newlines, and perhaps the verbosity? I

问题 Code: <?php echo "Hello World!\nSecond line"; ?> I'm trying to display this as two separate lines but the line break character doesn't work and instead a space gets printed inbetween the two. I've tried \r\n as well as .PHP_EOL. as well as placing the string in single quotes. None of them seems to work. So how do I print new lines in PHP? I'm working on phpDesigner 8 回答1: Use nl2br() to turn the new lines into HTML <br/> elements: <?php echo nl2br("Hello World!\nSecond line"); ?> 回答2: The

问题 I'm new to the c language and used java before, so I'm not so familiar with some things... I want to read an indefinite number of integer until there's a new line. I know, that new line is ⁄n and I already have a code, so the integer are read until you type in a letter, but it doesn't stop, if there's a new line. #include <stdio.h> int main() { int i, numberOfNumbs=0,total=0,value, valsRead; float average; valsRead = scanf("%d",&value); while(valsRead>0) { numberOfNumbs++; total +=value;
