isainfo -b command to display the number of bits s

Use the isainfo -b command to display the number of bits supported by native applications on the running system.

The output from a SPARC, x86, or UltraSPARC system running the 32-bit Solaris operating environment appears as follows:

$ isainfo -b
32  

The output from a 64-bit UltraSPARC system running the 64-bit Solaris operating environment appears as follows:

$ isainfo -b
64

The command returns 64 only. Even though a 64-bit UltraSPARC system is capable of running both types of applications, 64-bit applications are the best kind of applications to run on a 64-bit system.
