Golang-执行命令

Question

Prompt as in golang to execute such command:

/bin/bash script.sh < text.txt

I execute a script with parameters so:

package main

import (
    "fmt"
    "os/exec"
    "log"
    "os"
)

func main() {
    argstr := []string{"script.sh", "arg1", "arg2"}
    out, err := exec.Command("/bin/bash", argstr...).Output()
    if err != nil {
        log.Fatal(err)
        os.Exit(1)
    }
    fmt.Println(string(out))
}

And here is how to transfer an output from the text file?

Answer 1

The command you should execute is:

/bin/bash -c 'script.sh < text.txt'

So

argstr := []string{"-c", "script.sh < text.txt"}

Bash will interpret input redirection and will do the job.
