Temporary Files and Directories: Efficient Data Management in Go

Introduction

In programming, we often need to create data that is not needed after the program exits. Temporary files and directories are useful for this purpose since they do not pollute the file system over time.

Temporary Files and Directories

In this challenge, you need to create temporary files and directories in Go.

Requirements

Use os.CreateTemp to create a temporary file.
Use os.MkdirTemp to create a temporary directory.
Use os.RemoveAll to remove the temporary directory.
Use os.WriteFile to write data to a file.

Example

$ go run temporary-files-and-directories.go
Temp file name: /tmp/sample610887201
Temp dir name: /tmp/sampledir898854668

Summary

In this challenge, you learned how to create temporary files and directories in Go using os.CreateTemp, os.MkdirTemp, os.RemoveAll, and os.WriteFile. Temporary files and directories are useful for creating data that is not needed after the program exits and do not pollute the file system over time.
