The os and bufio packages make text file manipulation incredibly simple.Īlthough the vast majority of the os package's functions are Unix-like, they all employ the Go style of error handling, which makes it simple to read error messages and debug code.

For direct communication with your operating system, there is a package called os that provides platform-independent functions. You probably heard when you got started with Go that it comes with everything you could possibly need as a programmer. To use the bufio package in your program, you should import it alongside other packages. The bufio package goes one step further by implementing buffering, making it useful for IO operations involving textual data. The bufio package builds upon the io.Reader and io.Writer interfaces, which are extensively used in the implementation of the majority of Go’s standard packages. The bufio package, which is a part of Go's standard library, is used for buffered input and output operations, hence the name.
