here is something you can start playing with:

```
package main

import (
"flag"
"fmt"
"log"
"net/http"
"os/exec"
"strings"
)

var (
addrFlag = flag.String("addr", ":", "server address:port")
)

func main() {
flag.Parse()
http.HandleFunc("/", helloWorld)
err := http.ListenAndServe(*addrFlag, nil)
if err != nil {
log.Fatal(err)
}
}

func helloWorld(w http.ResponseWriter, r *http.Request) {
cmd := exec.Command("ls", "/tmp")
out, err := cmd.Output()
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
fmt.Fprintf(w, ">>> %s\n", strings.Join(cmd.Args, " "))
fmt.Fprintf(w, "%s\n", string(out))
}

```

this will run the "ls" command on the server, not the client, though :)

and I left the button part as an exercize for the reader :P

I am a newby :)

Hi Dave,

I think what you want is to combine net/http (for the server part) with
os/exec (to invoke bash, though with your example you don't need a shell
and could execute the `ls` command directly). You'd need one or two
handlers; maybe browse this to understand more:
https://golang.org/doc/articles/wiki/

It's not specifically what you were asking, but this might be something
that could be done without Go at all, by emulating a full Linux system
entirely in the browser. For example: https://bellard.org/jslinux/

Cheers,

Jonathan

[go-nuts] can someone create an example for me of a webpage that can run a bash command ?

[David Brendlinger]

can someone create an example for me of a webpage that can run a bash 
command ?  

I would like a index.html that has a button on it.  you hit the button and 
it would do a ls /tmp >> myfile

Thank you in advance
