How to check your oracle client version 32 or 64 bit (HPUX)

64 Bit:
<oratest>:oravis>pwd
/visapp/visapp/visdb/9.2.0/bin
<oratest>:oravis>file oracle
oracle: ELF-64 executable object file – PA-RISC 2.0 (LP64)

32 Bit:
<oratest>:applvis>pwd
/visapp/visapp/visora/8.0.6/bin
<oratest>:applvis>file oracle
oracle: PA-RISC1.1 shared executable dynamically linked -not stripped
