Solaris doesn't ship a 64bit version of "bash" (yet ; I'll work on that
soon), right now the only 64bit shell shipped with the OS is ksh93, e.g.
- /usr/bin/ksh93 is a link to "isaexec" which selects a 32bit or 64bit
version of ksh93 based on /usr/bin/isalist output
- /usr/bin/i86/ksh93 is 32bit/i386
- /usr/bin/amd64/ksh93 is 64bit/AMD64
- /usr/bin/sparcv7/ksh93 is 32bit/SPARC
- /usr/bin/sparcv9/ksh93 is 64bit/SPARC
- /usr/bin/s390/ksh93 is 32bit/SystemZ
- /usr/bin/s390x/ksh93 is 64bit/SystemZ
