How To Find Linux System Bit Version 32 Bit or 64 Bit Version
There are There Method to Identify the Linux Operating System Bit version.
Is it 32 bit or 64 bit.
First Method
File command is used to identify the file type.
what type of file.
Is it Directory, or ASCII file or Image.
Here In the
/usr/bin directory
it contain list of the binary file
it contain the file name like "file"
if you run command like
You can identify the Linux operating system bit version.
similarly you can run the following command
rhel5-bash ~ # file /sbin/init
/sbin/init: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.8, stripped
Second Method
uname command is used to identify the system information
rhel5-bash ~ # uname -m
i686
Refer the Link >> what is uname command How to identity the system information.
Third Method
Command getconf
These command is used to identify to get the system configuration variables
rhel5-bash #getconf -a
command it will list of list of configuration variable
Here we can filter CPU bit version through following grep
rhel5-bash man # getconf -a

How to identify Linux operating system Bit version | Configuration Information Uname File /use/bin /sbin/init command.
Is it 32 bit or 64 bit.
First Method
File command is used to identify the file type.
what type of file.
Is it Directory, or ASCII file or Image.
Here In the
/usr/bin directory
it contain list of the binary file
it contain the file name like "file"

You can identify the Linux operating system bit version.
similarly you can run the following command
rhel5-bash ~ # file /sbin/init

Third Method
Command getconf
These command is used to identify to get the system configuration variables
rhel5-bash #getconf -a
command it will list of list of configuration variable
Here we can filter CPU bit version through following grep
rhel5-bash ~ # getconf -a | grep LONG_BIT
LONG_BIT 32List of getconfg variable
