如何查看linux page

查看os系统块的大小

[root@dg1 ~]# tune2fs -l /dev/sda1 |grep 'Block size'

Block size: 4096

[root@dg1 ~]#

查看os系统页的大小

[root@dg1 ~]# getconf PAGESIZE4096[root@dg1 ~]#

修改块的大小:

创建文件系统时，可以指定块的大小。如果将来在你的文件系统中是一些比较大的文件的话，使用较大的块大小将得到较好的性能。将ext2文件系统的块大小调整为4096byte而不是缺省的1024byte，可以减少文件碎片，加快fsck扫描的速度和文件删除以及读 *** 作的速度。另外，在ext2的文件系统中，为根目录保留了5%的空间，对一个大的文件系统，除非用作日志文件，5%的比例有些过多。可以使用命令

# mke2fs -b 4096 -m 1 /dev/hda6

将它改为1%并以块大小4096byte创建文件系统。

使用多大的块大小，需要根据你的系统综合考虑，如果系统用作邮件或者新闻服务器，使用较大的块大小，虽然性能有所提高，但会造成磁盘空间较大的浪费。比如文件系统中的文件平均大小为 2145byte，如果使用4096byte的块大小，平均每一个文件就会浪费1951byte空间。如果使用1024byte的块大小，平均每一个文件会浪费927byte空间。在性能和磁盘的代价上如何平衡，要看具体应用的需要。

systeminfo | find "system model" /i

wmic bios get serialnumber 获取硬件序列号

"wmic csproduct get name" 获取型号

远程： systeminfo /s computername

wmic /node:"IPorCOMPUTERNAME" bios get serialnumber

WMIC /NODE:"computer1" /USER:"domainname\username" /PASSWORD:"userpassword" OS GET Caption,CSDVersion,CSName

如何获取电脑序列号的两种方法： 第二种可以获取域中远程的电脑http://support.microsoft.com/kb/558124

测试在中：win7可以被远程wmic xp不行，似乎不同品牌机器也不能被远程wmic

今天加一个dmidecode ,这个是linux下的查看硬件工具，也有windows 版本

装了之后必须去安装目录下才能用命令

【例】将当前系统BIOS，CPU，主板等信息输出到一个HTML网页文件，命令如下：

：：得到系统信息.bat，运行bat文件即可

::系统信息输出到HTML文件,查看帮助： wmic /?

::wmic [系统参数名] list [brief|full] /format:hform >|>>[文件名]

wmic bioslist brief /format:hform >PCinfo.html

wmic baseboard list brief /format:hform >>PCinfo.html

强大的命令行工具wmic

.wmic=Microsoft Windows Management Instrumentation

2. C:\WINDOWS\system32\wbem 下的东西，特别是.xsl格式化文件，实现wmic的格式化输出

如wmic /output:c:\process.html process list /format:htable.xsl

/format:textvaluelist.xsl

/format:hform.xsl

/format:htable.xsl

/format:csv.xsl

/format:xml.xsl

3.wmic可以做什么？系统管理、远程主机信息获取。。。都可以

4.wmic /?

查看wmic对象有何可用属性: wmic 对象名称 get /? 例如

wmic process get /?

查看wmic对象某个属性的值: wmic 对象名称 get 对象某个属性 例如

wmic process get name

PROCESS - 进程管理

::列出进程的核心信息,类似任务管理器

wmic process list brief

::新建notepad进程

wmic process call create notepad

::列出进程的信息

wmic process get caption,handle,commandline,executablepath

::结束进程

wmic process [handle/PID] delete

wmic process [handle/PID] call terminate

::结束svchost.exe进程,路径为非C:\WINDOWS\system32\svchost.exe的

wmic process where "name='svchost.exe' and ExecutablePath<>'C:\\WINDOWS\\system32\\svchost.exe'" call Terminate

::结束svchost.exe进程,路径为C:\WINDOWS\svchost.exe的(关键点：路径中的\一定要换成\\)

wmic process where "name='svchost.exe' and
