Create a brand new file in Go (Golang)

To create a brand new empty file in Go, use the os.Create() operate.

• It creates a brand new file if it doesn’t exist, with the file mode 0666, for studying and writing.
• It truncates the file if it exists, which signifies that the contents of the file are eliminated with out deleting the file.
• The returned file descriptor is open for studying and writing.
• If there may be some drawback, the operate returns an error of sort *os.PathError.

package deal important

import (
    "fmt"
    "log"
    "os"
)

func important() {
    f, err := os.Create("testFile.txt")
    if err != nil {
        log.Deadly(err)
    }
    defer f.Shut()
    fmt.Println(f.Title())
}

At all times bear in mind to shut the open file descriptor whenever you end working with the file in order that the system can reuse it:

You possibly can then write information to this file. See how to do that in one among our earlier tutorials right here.
