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

isainfo -v

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"

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 Show Sample Output

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
This is sample output - yours may be different.

grep -q '\<lm\>' /proc/cpuinfo && echo 64 bits || echo 32 bits
