Hello.
I have problems running 2 commands.
When the second COMMAND2 fail this return os.Exit(2) but my program never
finish. If I see the process using ps ax I can see COMMAND2 <defunct>
If I run this 2 programs in linux command line, this work fine, but doesnt
work in go.
Could you help me? please
Thanks ins advance
This is my code
var cmd1_stderr bytes.Buffer
cmd1 := exec.Command("COMMAND1", args_1...)
cmd1.Stderr = &cmd1_stderr
var cmd2_stderr bytes.Buffer
cmd2 := exec.Command("COMMAND2", args_2...)
cmd2.Stderr = &cmd2_stderr
pipe, err := cmd1.StdoutPipe()
if err != nil {
// show error
}
cmd2.Stdin = pipe
err1 := cmd1.Start()
err2 := cmd2.Start()
if err1 == nil && err2 == nil {
done := make(chan error, 1)
go func() {
done <- cmd1.Wait()
done <- cmd2.Wait()
}()
select {
case cmd_err := <-done: // process finish
if cmd_err != nil {
// show error
} else {
// finish ok
}
}
}
