Hi,

I am newbie in Linux world.. I have good command in HP-UX.. So when I started working with Linux everytime comparing is coming in my mind..

It seems eveything here in GUI based window.. I would like to know about following information.

1) How I can find out existing HW information from command line (Like ioscan in HP-UX).
2) Is there any way to tune KERNEL ?
3) What is the basic difference between FS ?
4) Can I increase FS online ?
5) How to create FS from command line ? Do I need to use FDISK
everytime ?

Thanks in advance for your valuable suggestion

Sorry forget to inform that I am using HP Itanium server & Linux version is 2.4.18

Hi,

1) Don't know. (I use GUI).

2) Yes, certainly. During booting with boot parameters and during compilation. You need (a) book(s) for that. Try also http://www.kernelnewbies.org/ or, if you really want it the hard way http://www.linuxfromscratch.org/ (I never did).

3) What is FS standing for? File-system? Please clarify.

don't know what information ioscan returns - but there is a bunch of information available in the /proc dir - try reading all the files in there for a start

You can probe the pci bus with
This command is really useful for customizing your kernel.
There is a similar command for the isa bus, but I'm not familiar with it.
Maybe isadump?

You can "tune the kernel" by compiling a new one optimized for your system.

You need fdisk or cfdisk to create the partitions and mke2fs to create an ext2 or ext3 filesystem.

I'm not sure if I understand your other questions.

Use the /proc interface to gather information about hardware for example the file /proc/scsi/scsi will display all attached scsi devices. search google for proc inteface, you will find it very powerfull. You can also add and remove deivices with ease.
to tune kernel run make menuconfig in directory /usr/src/linux (for most distributions)
what kind of fs r u talking about ext2?
the command mke2fs can be used to create file systems
