See if the Linux machine is a 32-bit or 64-bit method

To see whether a Linux machine is a 32-bit or 64-bit method:

File/sbin/init or File/bin/ls
/sbin/init:elf 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for Gnu/linux 2.6. Stripped,

If the display 64-bit is 64 bits;

File/sbin/init
/sbin/init:elf 32-bit LSB executable, Intel 80386, version 1 (SYSV), for Gnu/linux 2.2.5, dynamically linked (uses shared LIBS), stripped

32bit if it is displayed as a + bit;

Uname-a
Linux pmx002**.**.** 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT all x86_64 x86_64 x86_64 gnu/linux

X86_64 represents 64-bit machines

Uname-a
Linux pmx0**.**.** 2.6.9-5.elsmp #1 SMP Wed Jan 5 19:30:39 EST 2005 i686 i686 i386 Gnu/linux

i686 represents 32-bit machines

i686 is only a subset of the i386, supported CPUs starting from Pentium 2 (686), the previous model is not supported.

Note:

1. i386 applies to all 32-bit CPUs of Intel and AMD. and via 32 CPU with X86 architecture.

Intel platforms include 8086,80286,80386,80486, Pentium Series (1.2.3.4), Celeron series, Pentium D series

and Centrino P-m,core duo and so on.

2. x86_64 applies to Intel's Core 2 Duo, Centrino Core 2 Duo, and Xeon and AMD Athlon64/x2, SEMPRON64/X2, Duron64 and other 64-bit CPUs with X86 architecture.

3. PPC applies to Apple Macintosh G3, G4, G5, PowerBook, and other Non-intel models

The installation DVD includes more software than the installation CD, and the installation DVD also includes two graphical interfaces (KDE and GNOME).

4.Jigdo

Fedora distributions can also be downloaded via Jigdo. Jigdo can speed up the download of the ISO image of the installation disk. Unlike the BT download waiting task complete, Jidgo automatically locates the fastest mirror server (via the Fedora Image Manager) and downloads the required files from it. To reduce the amount of network traffic required, you can have Jigdo scan the existing DVD or CD media. This feature is especially useful for the following users.

getconf Long_bit
Run the following command on 32-bit and 64-bit machines with the following results:
[[email protected] ~]$ getconf long_bit
64

[Email protected]/]# getconf long_bit
32
