Golang : Split strings into command line arguments
Problem :
You have a string and you want to split the string into command line arguments in Golang.
Solution :
Use the strings.Split()
function to break the string into a splice with each word as element.
For example :
package main
import (
"fmt"
"os/exec"
"strings"
)
func main() {
cmdLine := "ls -la"
//split into a splice
splitArgs := strings.Split(cmdLine, " ")
fmt.Println("The argument is " + cmdLine)
fmt.Println("The first argument is " + splitArgs[0])
fmt.Println("The second argument is " + splitArgs[1])
cmd := exec.Command(splitArgs[0], splitArgs[1:]...)
// capture the exec.Command output
output, err := cmd.Output()
if err != nil {
fmt.Println(err)
}
fmt.Println(string(output))
}
Sample output :
The argument is ls -la
The first argument is ls
The second argument is -la
