Setting process name (as seen by `ps`) in Go

Question

The following (rightfully) doesn\'t work:

package main

import (
        \"os\"
        \"time\"
)

func main() {
        os.Args[0] = \"custom name\"
               


        

Answer 1

To change a process name on Linux, you need to use the prctl system call combined with the PR_SET_NAME option.

At the moment, I don't think you can do this in Go code. You can, however, build a small C module to do this and then integrate it into your Go build.
