Check if system is 32bit or 64bit

Needed a quick way to see if my server distro that I setup years ago was running 32bit or not, since with time I had forgotten.

Note: does not check _hardware_ e.g. /proc/cpuinfo but rather the kernel installed

Check if *hardware* is 32bit or 64bit

This command tell you if your hardware is 32 or 64 bits even if you install a 32bits OS on a 64 bits hardware.

If your distro don't support the -q switch, try doing :

grep &>/dev/null '\<lm\>' /proc/cpuinfo && echo 64 bits || echo 32 bits

Check if x86 Solaris based system is 32bit or 64bit

This is likely only valid on Solaris based systems. Unfortunately a lot of the more universal techniques for determining if a system is 32bit or 64bit on x86 solaris fail to give much more information than "i86pc"

Know a better way?

If you can do better, submit your command here.

What others think

It's a nice way to detect the HARDWARE word size, but for the kernel, the uname -m is the best option

Duplicated?

Comment by MarxBro 22 weeks and 3 days ago

@bkmeneguello: Good catch, I stand better informed thanks!

@MarxBro: I have no idea, I searched for it to no avail and didnt bother looking a lot, this is mostly for personal use anyway, sorry if it causes confusion!
