简介：在windows下，我们通过计算机-属性 来查看相关的系统信息：系统名称，cpu，内存等等，同样，在linux下面，我们可以通过本文提供的方法来查询相关信息。
1. 查询系统版本
1.1终端输入：file /bin/ls root@hyk-ubuntu:/proc# file /bin/ls/bin/ls: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped 1.2终端里输入：lsb_release -a结果： No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 6.10 Release: 6.10 Codename: edgy
1.3终端里面输入：cat /etc/issue实例：root@hyk-ubuntu:/proc# cat /etc/issueUbuntu 11.04 \n \l
2. 查询内核信息
2.1终端里输入：uname -r
实例：root@hyk-ubuntu:/proc# uname -r2.6.38-8-generic
2.2终端里输入：cat /proc/version
实例：root@hyk-ubuntu:/proc# cat /proc/versionLinux version 2.6.38-8-generic (buildd@vernadsky) (gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu3) ) #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011
3. 查询内存信息
3.1终端里输入：top实例：root@hyk-ubuntu:/proc# toptop – 16:55:22 up 2:16, 3 users, load average: 0.05, 0.06, 0.11Tasks: 184 total, 2 running, 181 sleeping, 0 stopped, 1 zombieCpu(s): 9.8%us, 4.6%sy, 0.0%ni, 85.6%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%stMem: 2018672k total, 1848124k used, 170548k free, 79768k buffersSwap: 2052092k total, 0k used, 2052092k free, 905128k cached对输出的解释：total:总计物理内存的大小;used:已使用多大;free:可用有多少;Shared:多个进程共享的内存总额;Buffers/cached:磁盘缓存的大小;第三行(-/+ buffers/cached):used:已使用多大;free:可用有多少。 3.2终端里输入：free实例：root@hyk-ubuntu:/proc# free total used free shared buffers cachedMem: 2018672 1956216 62456 0 63548 988136-/+ buffers/cache: 904532 1114140Swap: 2052092 8 2052084解释：同上
3.3终端里输入：cat /proc/meminfo实例：root@hyk-ubuntu:/proc# cat /proc/meminfoMemTotal: 2018672 kBMemFree: 130160 kBBuffers: 69452 kBCached: 966992 kBSwapCached: 0 kBActive: 1066168 kBInactive: 717752 kBActive(anon): 686088 kBInactive(anon): 217156 kBActive(file): 380080 kBInactive(file): 500596 kBUnevictable: 36 kBMlocked: 36 kBHighTotal: 1145544 kBHighFree: 6852 kB4. 查询cpu信息
4.1终端里输入：cat /proc/cpuinfo实例：root@hyk-ubuntu:/proc# cat /proc/cpuinfoprocessor: 0vendor_id: GenuineIntelcpu family: 6model: 15model name: Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHzstepping: 11cpu MHz: 800.000cache size: 4096 KB………………5. 查询硬盘信息
5.1终端里输入：df -h实例：root@hyk-ubuntu:/proc# df -h文件系统 容量 已用 可用 已用%% 挂载点/dev/sda1 109G 2.8G 100G 3% /none 980M 692K 979M 1% /devnone 986M 1.8M 984M 1% /dev/shmnone 986M 104K 986M 1% /var/runnone 986M 0 986M 0% /var/lock
大多数人想要改造这个世界，但却罕有人想改造自己。
