Go: Create a temporary file or directory

File

Use ioutil.TempFile in package io/ioutil to create a temporary file:

file, err := ioutil.TempFile("dir", "prefix")
if err != nil {
	log.Fatal(err)
}
defer os.Remove(file.Name())

fmt.Println(file.Name()) // For example "dir/prefix054003078"

The call to ioutil.TempFile

To put the new file in os.TempDir(), the default directory for temporary files, call ioutil.TempFile with an empty directory string.

Directory

Use ioutil.TempDir in package io/ioutil to create a temporary directory:

dir, err := ioutil.TempDir("dir", "prefix")
if err != nil {
	log.Fatal(err)
}
defer os.RemoveAll(dir)

The call to ioutil.TempDir

To put the new directory in os.TempDir(), the default directory for temporary files, call ioutil.TempDir with an empty directory string.
