The isainfo utility is used to identify various attributes of the instruction set architectures supported on the currently running system. Among the questions it can answer are whether 64-bit applications are supported, or whether the running kernel uses 32-bit or 64-bit device drivers.
• Run isainfo command on a 32-bit x86 platform.
# isainfo -v 32-bit i386 applications
# isainfo -k i386
• Run isainfo command on a 64-bit operating system on a 64-bit SPARC processor.
# isainfo sparcv9 sparc
# isainfo -n sparcv9
# isainfo -v 64-bit sparcv9 applications 32-bit sparc applications
# isainfo -vk 64-bit sparcv9 kernel modules
