Change Process Name in Go: Complete Guide

In Go language, it is possible to change the process name by making a system call.

Here is an example code that uses the SysProcAttr structure in the syscall library and the SetProcTitle function to modify the process name.

package main

import (
	"syscall"
)

func SetProcTitle(title string) {
	var argv0StrPtr uintptr
	argv0StrPtr = uintptr(unsafe.Pointer(syscall.StringBytePtr(title)))
	syscall.Syscall(syscall.SYS_PRCTL, syscall.PR_SET_NAME, argv0StrPtr, 0)
}

func main() {
	SetProcTitle("new-process-name")
	select {}
}

Please note that this code utilizes the syscall library and can only be used on a Linux system. For Windows systems, a similar approach can be implemented.

It should also be noted that changing the process name may affect the system’s monitoring and debugging functions, so caution should be exercised when using it.
