I am able to get the following command to open a new terminal and execute the command when I directly input it inside a terminal, but I can not get it to work when I use the exec.Commmand function in go.
osascript -e 'tell application "Terminal" to do script "echo hello"'
I think the issue lies within the double and single quotes, but I am not exactly sure what is causing the error.
c := exec.Command("osascript", "-e", "'tell", "application", `"Terminal"`, "to", "do", "script", `"echo`, `hello"'`)
if err := c.Run(); err != nil {
fmt.Println("Error: ", err)
}
As of now the code is returning Error: exit status 1, but I would like the code to open a terminal window and execute the command.
After playing some time found this:
cmd := exec.Command("osascript", "-s", "h", "-e",`tell application "Terminal" to do script "echo test"`)
Apparently you should give the automator script in 1 argument and also use ticks (`) as the string literals for go.
"-s", "h"
is for automator program to tell you human readable errors.
My complete test code is as follows:
package main
import (
"fmt"
"os/exec"
"io/ioutil"
"log"
"os"
)
// this is a comment
func main() {
// osascript -e 'tell application "Terminal" to do script "echo hello"'
cmd := exec.Command(`osascript`, "-s", "h", "-e",`tell application "Terminal" to do script "echo test"`)
// cmd := exec.Command("sh", "-c", "echo stdout; echo 1>&2 stderr")
stderr, err := cmd.StderrPipe()
log.SetOutput(os.Stderr)
if err != nil {
log.Fatal(err)
}
if err := cmd.Start(); err != nil {
log.Fatal(err)
}
slurp, _ := ioutil.ReadAll(stderr)
fmt.Printf("%s
", slurp)
if err := cmd.Wait(); err != nil {
log.Fatal(err)
}
}
PS: osascript is the command line interface for Automator app in macOS.
