Easy and direct way to find this out. Show Sample Output
125getconf LONG_BIT -
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 Show Sample Output
21getconf LONG_BIT -
7sudo lshw -C cpu|grep width

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 bits2grep -q '\<lm\>' /proc/cpuinfo && echo 64 bits || echo 32 bits -
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" Show Sample Output

archarmv7lgetconf LONG_BIT32 So I prefer the getconf alternative.uname -poutputs the processor info (what it is capable of), butuname -moutputs the OS info (what is actually installed)? The -m stands for machine, so I'm not sure.
