I have an script that reads the file and compares the string by a pattern, if it returns false it will delete the line on the .txt file.
This is my code
const readline = require('readline');
const lineReplace = require('line-replace')
const fs = require('fs');
const inputFileName = './outputfinal.txt';
const readInterface = readline.createInterface({
input: fs.createReadStream(inputFileName),
});
let testResults = [];
readInterface.on('line', line => {
testResult = test(line);
console.log(`Test result (line #${testResults.length+1}): `, testResult);
testResults.push({ input: line, testResult } );
if (testResult == false){
console.log(`Line #${testResults.length} will get deleted from this list`);
lineReplace({
file: './outputfinal.txt',
line: testResults.length,
text: '',
addNewLine: false,
callback: onReplace
});
function onReplace({file, line, text, replacedText}) {
};
};
});
// You can do whatever with the test results here.
//readInterface.on('close', () => {
// console.log("Test results:", testResults);
//});
function test(str){
let regex = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/; // email regex
str = str.split(",");
// string should be of length 3 with str[1] number of length 7
if(str && str.length === 3 && Number(str[1]) && str[1] ) {
let temp = str[0].split("-");
// check for 85aecb80-ac00-40e3-813c-5ad62ee93f42 separately.
if(temp && temp.length === 5 && /[a-zA-Z\d]{8}/.test(temp[0]) && /[a-zA-Z\d]{4}/.test(temp[1]) && /[a-zA-Z\d]{4}/.test(temp[2]) && /[a-zA-Z\d]{4}/.test(temp[3]) && /[a-zA-Z\d]{12}/.test(temp[4])){
// email regex
if(regex.test(str[2])) {
return true;
} else {
return false;
}
} else {
return false
}
} else {
return false;
}
}
But isn't working, returns error no such file or directory, I dont think that is the correct way to do a line remover script
from Script dont fuction properly
