<tt>Is i.86 means 32 bit ( I mean to say if 'uname -m' gives i686 which is generally for xeon processor is it 32 bit or 64 bit ) somewhere I read that if it shows as i.XX (means i386/i486/i586/i686) means 32 bit if it shows as i.xx-64 (i686-64) then it is 64 bit ? if i run #file /bin/ls it show me /bin/ls: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), stripped does it mean my OS is 32 bit and all files are compiled in 32 bit ? output of uname -m shows i686 in my linux box (machine is a HP-xeon processor) I have installed redhatES 3.0 kernel 2.4.21-4 ELsmp. Can you give ur view please.</tt> Arun Sopanrao Nale <table><tr><td bgcolor=#ffffff>Notice: The information contained in this e-mail message and/or attachments to it may contain confidential or privileged information.
