Go语言学习日记【十三】GOLANG调用SHELL命令

// go调用外部命令，并在运行过程中传递参数


// hello.go
package main

import (
    "fmt"
)

func main() {
    fmt.Println("Hello, What's your favorite number?")
    var i int
    var j int
    fmt.Scanf("%d", &i)
    fmt.Println("1 Ah I like ", i, " too.")
    fmt.Scanf("%d", &j)
    fmt.Println("2 Ah I like ", j, " too.")
}



// 调用hello.go
package main


import (
    "os"
    "os/exec"


)



func main()  {
    cmd := exec.Command("go", "run","hello.go")
    cmd.Stderr = os.Stderr
    cmd.Stdout = os.Stdout
    cmd.Stdin = os.Stdin
    cmd.Run()

}

package main


import (
   "fmt"
   "os/exec"
)


func main(){
    var cmd *exec.Cmd
    v := "/dev/sdb1"
    com = fmt.Sprintf("mount -l | grep %s | cut -d ' ' -f 3",v)
    cmd = exec.Command("/bin/bash","-c",com)
    out,err := cmd.CombinedOutput()
    if err != nil {
        fmt.Println(err)
    }
    fmt.Println(string(out))
}

package main

import (
    "fmt"
    "os/exec"
    "strings"
    "bytes"
)
func main() {
        cmd:=exec.Command("sh","-c","ps aux|grep 'cli -m server'|grep Sl")
        stdout:=&bytes.Buffer{}
        cmd.Stdout=stdout
        cmd.Run()
        fmt.Println(len(strings.Split(strings.TrimRight(stdout.String(),"\n"),"\n")))
        fmt.Println(strings.Split(strings.TrimRight(stdout.String(),"\n"),"\n"))
}
