Re: OS mode 32/64 bit?

'uname -m' will have '64' in it if it's either intel x86 or amd x86.

Re: OS mode 32/64 bit?

Hi,

"uname -m" according to man will print the machine hardware name. Not the OS mode. Can a 64 bit OS run on 32 bit hardware? and vice-versa. Plz clarify this.

Thnx,
Manu

uname -a if has x_64 in its outpu its 64 bit mode.

or

file init

will show if the file is 64 bit executable.. then the os is in 64 bit mode.
