问题 I should write a function to get some information about the system (the most important information is the the architecture). I found the function uname which can be used including sys/utsname.h . Well, though I googled and I read the documentation, I couldn't find any example of the function and I don't understand how to use uname. Anyone can explain me how to use it? it would be great if you can write an example, too. Thanks in advance. 回答1: First, include the header: #include <sys/utsname.h

How to change version string of the kernel?

由 百般思念 提交于 2020-01-21 04:30:33
问题 I'm very new to Linux and very new to building/compiling my own kernel. For starters, I'm just trying to figure out how to change the version string of my kernel. For instance, when I do uname -a, it prints out "Linux localhost.localdomain 3.11.10-100.fc18.i686". I'd like to customize that, but I'm not sure what file to edit. I know it must be some file in my kernel directory, but I've been going through them with no luck. Any help would be great! 回答1: At the top of the top-level Makefile,

问题 I need to determine the type of OS the PHP server is running on. By type, I mean strings like "windows" or "linux", not "wince", "winnt" etc. So far, I have to leads: PHP_OS and uname(), the later being more reliable than the earlier (PHP_OS says what OS PHP was built on - according to documentation). 回答1: It's important to know that no non-Windows OS string is going to contain the text "win", and no non-OSX OS string is going to contain the word "darwin", and so on. Detecting the OS is easy.

How to modify the Linux kernel to change the version string that uname returns?

由 随声附和 提交于 2019-12-08 02:41:53
问题 I'm working with an old (2.6.33.2) version of embedded Linux and have been asked to change the kernel so that differently patched kernel images can be told apart. At the moment, uname -v outputs e.g. "#1 Wed Sep 11 07:07:51 BST 2013 . Hence I'd like to change this so that any subsequent patches change the #1 part to a revision number defined as part of the patch (and to change the date part to be the date of the latest kernel patch), but I can't see where in the kernel this is set up.
