gobash

Execute commands, scripts, executables in the go environment with live log output.

Example of use

Run

Run executes commands and can actively end them, returning logs and error messages in real time, recommended.

    arg := "for i in $(seq 1 5); do echo 'test cmd' $i;sleep 1; done"
    ctx, _ := context.WithTimeout(context.Background(), 3*time.Second) // timeout control

    result := Run(ctx, "bash", "-c", arg)
    // real-time output of logs and error messages
    for v := range result.StdOut {
        fmt.Printf(v)
    }
    if result.Err != nil {
        fmt.Println("execute command failed,", result.Err.Error())
    }

Exec

Exec is suitable for executing a single non-blocking command, outputting standard and error logs, but the log output is not real-time, note: if the execution of the command is permanently blocked, it will cause a concurrent leak

    arg := "for i in $(seq 1 5); do echo 'test cmd' $i;sleep 1; done"
    out, err := Exec("bash", "-c", arg)
    if err != nil {
        return
    }
    fmt.Println(string(out))
