The code below uses Nodejs to read the file.
<lang JavaScript>
const fs = require("fs");
const readline = require("readline");
const args = process.argv.slice(2);
if (!args.length) {
console.error("must supply file name");
process.exit(1);
}
const fname = args[0];
const readInterface = readline.createInterface({
input: fs.createReadStream(fname),
console: false,
});
let sep = "";
readInterface.on("line", (line) => {
if (line.startsWith(">")) {
process.stdout.write(sep);
sep = "\n";
process.stdout.write(line.substring(1) + ": ");
} else {
process.stdout.write(line);
}
});
readInterface.on("close", () => process.stdout.write("\n"));
</lang>
