Linux kernel - 32/64 bit

[MikeL_4]

How can you tell in Linux if the server is running 32 or 64 bit ??

[John Poff · Accepted solution]

One way to tell is by doing a 'uname -a'. If you are running a 64-bit kernel you'll probably see 'x86_64' instead of 'i686' or 'i386', assuming you are running on an Intel processor.

Wou can check commands like below

1. uname -a

2. file /sbin/init

3. cat /etc/redhat-release
