Re: [go-nuts] Having difficulty converting []byte to float

After talking with a coworker it seems that "grep" returns a \n after its output. That was the bugger keeping my initial efforts from working. Grep was meant for "human consumption". I will need to look into buffio and scanner as Tamas suggested. On Friday, May 18, 2018 at 11:06:46 AM

Drilling down farther for the heck of it os/exec/exec.go func (c *Cmd) Output() ([]byte, error) { if c.Stdout != nil { return nil, errors.New("exec: Stdout already set") } var stdout bytes.Buffer c.Stdout = captureErr := c.Stderr == nil if captureErr { c.Stderr = {N: 32 << 10} }

[go-nuts] Having difficulty converting []byte to float

The input is string, so use strconv.ParseFloat, or ParseInt (will there be non-integer number of cpus?) Just trim the LF with strings.TrimSpace. For production use, leave out the grep and bash, read the output lines directly with bufio.Scanner. -- You received this message because you are
