You will realise that the messages scrolled down before you could read

them. To see them page by page type "dmesg | less" or "dmesg | more".

The dmesg command provides valuable information about the hardware

devices detected by Linux. It also helps in knowing if there was some

problem somewhere. Like if you see the line: sb: Interrupt test on

IRQ5 failed - device disabled. It means there was a problem with

setting up of the Sound Blaster sound card at IRQ5. If you get such

correctly under Linux.

The BASH shell has a lot of ease of use. If you like working a lot on

the command line, you will find it very easy. The bash shell allows

type "clear".

Another important command is df. Just type "df" and you will see

something like:

Filesystem 1024-blocks Used Available Capacity Mounted on

/dev/hda6 388362 341804 26501 93% /

/dev/hda5 614672 572176 42496 93% /dosd

This gives information of all your mounted hard disk partitions,

available space and used space. The space shown is 1024 blocks which

is 1024 bytes or one Kilo Byte. It also shows at which directory the
