Hi @Davennix and welcome to the GitHub Community Forums.

Your last two messages are a bit unconstructive as they do not contribute to the discussion. Next time, please consider adding extra information to your question such as a clearer explanation or the programming language you’re working in to increase the chances of someone being able to answer your question.

From your code I’m guessing you’re using NodeJS. Note that your method reads the entire file, which might be fine as longs as the file isn’t too big.

You could split up the contents of the file by line by using the split() function with the newline character:

content.split('\n')
// or
content.split('\r\n') // sometimes on Windows, check what works

in order to obtain the first line of the file. You could then use a function like writeFileSync() in order to write the new file after stripping out the first line. Note that content is just a string containing the file contents and you can do any string operation on it.
