I am creating Go snippet to write log into a file using os module, You can use the writing into the file feature for logging, saving data, store data in file etc. You can read data from a file or write something into the file using golang os package.

To do this, the Go io package provides interfaces io.Reader. This tutorial has the following sections. We will also learn how to write to a file concurrently. The os.Stat function returns the FileInfo structure describing the file. To work with files in Go, we use the os, ioutil, and fmt packages. We read files, write to files, create files, list files, and determine their size and modification time. However, if you just want to interpolate and then write the string result straight to file, this post demonstrates how. In this tutorial, we will learn how to write data to files using Go. Go file tutorial shows how to work with files in Golang. Go is providing os package to create/read/write the file. In Go, input and output operations are achieved using primitives that model data as streams of bytes that can be read from or written to. Template File Processing in Go tutorial go templates In a previous post I demonstrated how to get a Go template's interpolated string result.

The read and write files are very important features of any programming language.

- 1 With the growing of the software, there are many algorithms and methods to ensure data security.

And it uses the Write() method instead of WriteString().

This golang tutorial help to read and write file using Golang. The only difference is that the bytes are written to the file as a sequence of bytes, not as a string.
