查看系统内核版本:

# uname -a

查看系统版本:

# more /etc/redhat-release

查看内核版本gcc版本

# more /proc/version
查看cpu 信息

# grep “model name” /proc/cpuinfo

# more /proc/cpuinfo
查看cpu 的位数

# getconf LONG_BIT

查看内存信息

# more /proc/meminfo

查看系统资源使用情况

“vmstat reports information about processes, memory, paging, block IO, traps, and cpu activity.

#vmstat 5

“display Linux tasks
#top

“Display amount of free and used memory in the system

查看磁盘i/o

“用iostat查看磁盘/dev/sdc3的磁盘i/o情况，每两秒刷新一次

$ iostat -d -x /dev/sdc3 2

查看用户磁盘限额

quota [-u] <username>
