# Uname-
Linux euis1 2.6.9-55. elsmp #1 SMP Fri APR 20 17:03:35 EDT 2007 i686 i686 i386 GNU/Linux
(View the kernel information of the current operating system)

# CAT/etc/issue | grep Linux
Red Hat Enterprise Linux as Release 4 (nahant Update 5)
(View the released version of the current operating system)

# CAT/proc/cpuinfo | grep name | cut-F2-D: | uniq-C
8 Intel (r) Xeon (r) CPU e5410 @ 2.33 GHz
(We can see eight logical CPUs and the CPU model)

# CAT/proc/cpuinfo | grep physical | uniq-C
4 physical ID: 0
4 physical ID: 1
(It means two 4-core CPUs)

# Getconf long_bit
32
(This indicates that the current CPU runs in 32bit mode, but does not indicate that the CPU does not support 64bit)

#< SPAN class = "apple-converted-space"> CAT/proc/cpuinfo | grep flags | grep 'lm '| WC-L
8
(if the result is greater than 0, 64bit computation is supported. lm indicates long mode, and 64 bit for LM.)
