2018-11-17 11:13管道命令并使用命令重定向golang中的输出
Here is my code :
package main
import (
"fmt"
"os"
"os/exec"
"strconv"
"time"
)
func main() {
year, month, day := time.Now().Date()
monthI := int(month)
fmt.Println("toto")
date := strconv.Itoa(year)+"_"+strconv.Itoa(monthI)+"_"+strconv.Itoa(day)
nameSnapshot := "storedb@backup_"+date
args := []string{"snapshot",nameSnapshot}
cmd := exec.Command("zfs", args...)
err := cmd.Run()
if err != nil {
os.Stderr.WriteString(err.Error())
}
args = []string{"send",nameSnapshot,"|","gzip",">","backup_"+date+".gz"}
cmd = exec.Command("zfs", args...)
err = cmd.Run()
if err != nil {
os.Stderr.WriteString(err.Error())
}
}
I would like to do it in one command.
My second line the zfs send command seems not working.
How to pipe and redirect the ouput in golang with cmd.exec ?
Regards
