Answer Posted / sachinmali17

To get a clear idea about you OS (32bit or 64bit)
you can use following command,

root@ganesh ~]# file /usr/bin/file

/usr/bin/file: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped

[root@ganesh ~]#
