Go语言执行系统命令行命令的方法
本文实例讲述了Go语言执行系统命令行命令的方法。分享给大家供大家参考。具体如下：
执行Go代码时可以附加参数，包括要执行的命令和给命令的参数
packagemain
import(
"os"
"os/exec"
"fmt"
"flag"
"strings"
)
funcmain(){
command:=flag.String("cmd","pwd","Setthecommand.")
args:=flag.String("args","","Settheargs.(separatedbyspaces)")
flag.Usage=func(){
fmt.Fprintf(os.Stderr,"Usage:%s[-cmd<command>][-args<thearguments(separatedbyspaces)>]\n",os.Args[0])
flag.PrintDefaults()
}
flag.Parse()
fmt.Println("Command:",*command)
fmt.Println("Arguments:",*args)
varargArray[]string
if*args!=""{
argArray=strings.Split(*args,"")
}else{
argArray=make([]string,0)
}
cmd:=exec.Command(*command,argArray...)
buf,err:=cmd.Output()
iferr!=nil{
fmt.Fprintf(os.Stderr,"Thecommandfailedtoperform:%s(Command:%s,Arguments:%s)",err,*command,*args)
return
}
fmt.Fprintf(os.Stdout,"Result:%s",buf)
}
希望本文所述对大家的Go语言程序设计有所帮助。
