Getting Hardware information without opening Box on LInux

With Linux- FC6 running on Dell machine, How can I get hardware info of my machine?

"dmidecode " is the key command to fetch such info.

Command is readily available on most of Linuxes

Here is some more details on same command :
-t, --type TYPE
Only display the entries of type TYPE. TYPE can be either a DMI type number, or a comma-separated of type numbers, or a keyword from the following list: bios, system, baseboard, chassis, pro cessor, memory, cache, connector, slot. Refer to the DMI TYPES section below for details. If this option is used more than once, the set of displayed entries will be the union of all the given types. If TYPE is not provided or not valid, a list of all valid keywords is printed and dmidecode exits with an error. Mutually exclusive with --string.

[root@localhost drive_c]# dmidecode -t1
# dmidecode 2.7
SMBIOS 2.4 present.

Handle 0x0100, DMI type 1, 27 bytes.
