Calling “sed” from exec.Command

问题

I'm currently having trouble trying to run this code which is supposed to call the unix command sed to find and replace the string hello with goodbye in the file ./myfile.txt

This works fine if you run it from the command line, but if I try the same thing from my Go code....

command := exec.Command("sed", "-e \"s/hello/goodbye/g\" ./myfile.txt")
result,err := command.CombinedOutput()
fmt.Println(string(result))

Bit I just keep on getting this output

sed: -e expression #1, char 2: unknown command: `"'

Is there some sort of quote escaping going on or something to cause it to interpret the string wrong?

Any help would be appreciated

I believe the following works:

command := exec.Command("sed", "-e","s/hello/goodbye/g","myfile.txt")
