英文:
Calling "sed" from exec.Command
问题
我目前在尝试运行这段代码时遇到了问题，它应该调用Unix命令sed来查找并替换文件./myfile.txt中的字符串hello为goodbye。
如果你从命令行运行它，它可以正常工作，但是如果我尝试从我的Go代码中运行相同的命令...
command := exec.Command("sed", "-e \"s/hello/goodbye/g\" ./myfile.txt")
result,err := command.CombinedOutput()
fmt.Println(string(result))
但是我一直得到这个输出：
sed: -e expression #1, char 2: unknown command: `"'
是否有某种引号转义或其他导致它错误解释字符串的问题？
任何帮助将不胜感激。
英文:
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

我相信以下代码可以工作：
command := exec.Command("sed", "-e","s/hello/goodbye/g","myfile.txt")
英文:
I believe the following works:
command := exec.Command("sed", "-e","s/hello/goodbye/g","myfile.txt")
