Today's editor to share with you is to see how many bits of linux code introduction, I believe that many people do not understand, in order to let you better understand how many bits of code to view linux, so to sum up the following content, let's look down. I'm sure you'll get something.

1. Uname-a, armv7l indicates that the system is installed with 32-bit, but this result is not obvious. Those who are not familiar with linux systems cannot tell whether it is 32-bit or 64-bit.

[root@localhost local] # uname-a Linux localhost 3.4.0-perf-g18c6f85 # 1 SMP PREEMPT Thu Sep 11 12:05:53 2014 armv7l armv7l armv7l GNU/Linux

2. Getconf LONG_BIT (recommended), the result is very intuitive

[root@localhost local] # getconf LONG_BIT 32

The code about how many bits of linux is shared here, of course, not only the above and everyone's analysis methods, but the editor can ensure that its accuracy is absolutely no problem. I hope that the above content can have a certain reference value for everyone, and can be put into practice. If you like this article, you might as well share it for more people to see.
