Thanks,
You are right it is $! but my question that this throws up, is, if when
running x scripts the $! could return at some time the pid of a wrong command.
What I mean:
Imagine having two scripts (I know ls and df don't run long enough, it is just
used as an example):
1.)
ls
pid1s=$!
kill $pid1
Hi,
I wrote a bash script from which I call one c-program, that is mainly a loop.
But in the script I would like to be able to just kill the loop. So I thought,
that there must be a way how to get the PID of a program when starting it
(then save it in a variable and later use it to call kill). Is t
The "funny/strange" thing for me is, that I can pass at boot the option
"single" and am asked for the password AND CAN log in?!?!
Can anyone help me?? What's wrong with my image, what did I do wrong?
Thanks Pir

Hi,
I tried to make a initrd (root has to stay in ram) image by hand, following
the suggestions of the bootdisk HOWTO. So I copied almost everything to my
image, but when I boot I am prompted to type in my login name. But after doing
so I receive four lines of "Login incorrect" (automaticly) and t
I now know, what I missed:
if (ioctl(fd, HDIO_UNREGISTER_HWIF, hwif))
Just the little ioctl() ;-)

Hi,
I used the command hdparm -U 1 /dev/hdc1 to unregister the ide1 interface.

I do think, that you need a number as you find the following code in hdparm.c
case 'U':
if (!*p && argc && isdigit(**argv))
p = *argv++, --argc;
if(! p) {
fprintf(stderr, "expected hwif_nr\n");
exit(1);
}
sscanf(p++, "%i", &hwif);
unregister_hwif = 1;
break;

What I mean ist, that I want the entire system running from RAM. No swaping to
disk, no loading of not loaded/used commamds. What I want is something like a
copy of the filesystem system in the RAM. Imagine, that there would be no disk
anymore, after copying everything to RAM.

Hi again,
I would like to have my system (Linux kernel 2.4) moved to ram, after/before
booting and stay it there (do everything from there).
I have read I might need chroot, but no other information. Does anyone know,
where I could find some more info about this?

Hi,
I would like to know, how to tell hdparm to unregister ide1 (the secondary ide
channel). I tried with version 4.5:
hdparm -U 1
hdparm -U ide1
hdparm -U /proc/ide/ide1/channel
but it doesn't work. It just prints the help screen, not doing anything else.
Can someone please give me a hint?
Thank,
The Idea of a modul is interesting, but wouldn't that mean, that if I remove
the module I'll remove the whole IDE. I've hear that removing the /root could
cause problems. My disk is on a separate line anyway, so is there a way to
have a modul, that removes just the one line, leaving the other untou
Yes, but that is not my primary concern. I'll figure the HW out. What I want
to know, is if there is a command for rescan or reinitialize the IDE bus.

Is there a way to rescan the IDE Bus under Linux. (Not looking at the need of
HW). The only thing I want to know, is if I can rescan the Bus after power on.
I heard about hdparm -U and hdparm -R, but does it really make a rescan and
realizes the new HD?
Thx Pir
