command help required in emergency

[rituraj.goswami]

i need some help in commands.
1.
i want to edit the menu.lst of /boot/grub/ to tell that i need to install the 2rd of the 3 OS i have. and how do i set the Debian 5.0 default grub that i loads to a xmp file that i have.

2.
want to install, find and remove a .deb file.


3.
my /etc/resolv.conf gets rewritten every time i reboot. what to do.

For 2 and 3

2.
from command line you can use aptitude or apt-get. Aptitude more sophisticated, it registers all the packages and if a package which have installed for dependency resolving purpose and getting unneeded the aptitude removes it automatically.

You can even use synaptic a graphical package manager.

and read "man aptitude"

3.

Ithink the problem isn't a problem.

If you are using dhcp ,the dhclient rewrite /etc/resolv.conf on every network setup with the actual informations which have got from the dhcp server.

install? do you actually mean to boot? Open /boot/grub/menu.lst and change 'default' to your second OS starting from 0. For eg: If the entries in your menu.lst are as,

1. Debian
2. Debian single user mode
3. CentOS
4. Windows

and you want to boot CentOS by default instead of Debian, change Default to 2.

default 2

xmp? or xpm the splash image? Add splashimage entry as follows, assuming your splash image in in /boot/grub and Debian is in first partition of your harddisk

splashimage (hd0,0)/boot/grub/splash.xpm.gz

2. want to install, find and remove a .deb file.

as suggested above. 'man aptitude' and/or 'man dpkg'

[rituraj.goswami]

the grub is given by debian. now i nhave 3 OS.
debian, windows and rhel 5.3. so i can't change this order but i need to defaultly boot to rhgel 5.3.

[saivin]

Thats what I have tried to explain. Boot into Debian, open /boot/grub/menu.lst for editing and edit as above. See which entry is RHEL and change the vaule of 'default' accordingly (starting with 0).
