1) cd /usr/ports/sysutils/detach
have fun...
2) the code itself is rather simple and I wrote such detach.c by
myself on FreeBSD 3.4 before I had a chance to look into ports
collection. Here it is:
/*==========================================================
* detach.c
*----------------------------------------------------------
* Executes given as arguments programs having
* detached TTY at first.
*
* by Poige, poige@nm.ru
*==========================================================
*/
#include <unistd.h>
#include <sys/types.h>
#include <stdlib.h>
int main(int argc, char **argv)
{
/* executes another programs having detached
* tty at first
*/
return ! (
argv[1]
&& (fork () == 0)
&& (setsid () > 0)
&& (fork () == 0)
&& (execvp (argv[1], argv + 1) > 0)
);
}
> Would a utility like this be useful?
yes
> Is this functionality already available in a system utility?
in ports...
