it fixes the issue I'm a beginner ! , Approach with a simple for-loop
code :
string input = "book";
for (int i = 1; i < input.Length; i++)
    Console.WriteLine(string.Concat(input[0], input[i]));

I wish this helpful for you I use curl I want to get a certain phrase of it, the problem is that the entire file (that I am displaying using curl) consists of only 1 line. The phrase I want to extract form this file begins always with {"name":"headline","link": and it always ends with }}. , This will do
code :
grep -o -E '"name":"Rausschmeisser","link":"[^"]+"'
egrep -o '"name":"Rausschmeisser","link":"[^"]+' | cut -f8- -d\"

How can I add a character before a specific word, considering that I change another character in the middle of that word

it helps some times I have a code which replaces special characters with other characters, but I need to add another character before that word. For example,
code :
var str= 'hello zāi hi ē sure á ikr é'
var words = str.split(' ');
 if(word.match(/[āáēé]/g)) return 'a' + word;
 return word;
}).join(' ').replace(/[āáēé]/g, function(letter){
    case 'ā':
    case 'á':
        return 'a';
    case 'ē':
    case 'é':
        return 'e';

How do I make undo/redo in <textarea> to react on 1 word at a time, word by word or character by character?

will help you You can write a custom undo and redo, here's something to get you started. I simply save a state every time the user types 'space'.
code :
saveState = [];
var saveI = 0;

$('#inputRegion').on("keydown", function (event) {
	if (event.which == " ".charCodeAt(0)) {
		saveI = saveState.length -1;

function triggerUndo () {
	if (saveI >= 0) {

function triggerRedo () {
	if (saveI < saveState.length) {

function debug() {
	//removed, used for debugging.
textarea {
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<textarea id="inputRegion"></textarea>
<br />
<button onclick="triggerUndo()">Undo</button>
<button onclick="triggerRedo()">Redo</button>

Hope that helps If you want to remove a specific word from each string in a list you can use the str.replace() method in a list comprehension:
code :
l = ['බලනවා', 'නටනවා']
l = [s.replace('නවා', '') for s in l]
['බල', 'නට']
