os.Rename in goLang?

Function signature:

func Rename(oldpath, newpath string) error

What Rename does?

Rename renames (moves) oldpath to newpath. If newpath already exists and is not a directory, Rename replaces it. OS-specific restrictions may apply when oldpath and newpath are in different directories. If there is an error, it will be of type *LinkError.

#golang #go #os #rename #os_rename

As you may already know in Python you can format your string using format as below:

file_name = "/root/openvpn/{}.ovpn".format(my_file_name)
// Or
file_name = "/root/openvpn/%s.ovpn" % my_file_name

In golang you need to use Sprintf method of fmt package like follow:

var fileName = fmt.Sprintf("/root/openvpn/%s.ovpn", myFileName)

#python #golang #go #fmt #sprintf #format

environments in Golang:

To set a key/value pair, use os.Setenv. To get a value for a key, use os.Getenv. This will return an empty string if the key isn’t present in the environment.

Use os.Environ to list all key/value pairs in the environment. This returns a slice of strings in the form KEY=value. You can strings.Split them to get the key and value. Here we print all the keys:

package main

import (
        "os"
        "strings"
        "fmt"
)

func main() {
    os.Setenv("FOO", "1")
    fmt.Println("FOO:", os.Getenv("FOO"))
    fmt.Println("BAR:", os.Getenv("BAR"))

    fmt.Println()
    for _, e := range os.Environ() {
        pair := strings.Split(e, "=")
        fmt.Println(pair[0])
    }
}

If you want to implement "Python Capitalize" method in Go:

strings.Title(strings.ToLower("MYNAME")) // output: Myname

There is another method called ToTitle which is used for one character long (but to letters):

str := "dz"
fmt.Println(strings.ToTitle(str)) // output: Dz

#python #golang #go #ToLower #Title #strings #capitalize #ToTitle
