查看Linux硬件信息的命令汇总

读博士期间用到了十几台服务器，为了实时监控它们的情况，自己写了一个程序。下面这些Linux命令大多是那时总结的。

1. Number of Physical CPUs

cat /proc/cpuinfo | grep -i 'physical id' |sort -u | wc -l

2. Number of Cores on each physical CPU

cat /proc/cpuinfo | grep -i 'cpu cores' | sort -u | gawk '{print $4}'

3. Number of Total CPU Threads

cat /proc/cpuinfo |grep -i 'processor' | sort -u |wc -l  

4. HTSupported

cat /proc/cpuinfo |grep -i ‘ht’ | sort | wc -l

5. HTEnabled

6. CPU model

cat /proc/cpuinfo |grep 'model name' |uniq

7. Linux Distribution

cat /etc/issue |gawk 'NR <2'

8. Linux Kernel Version

uname -r

9. Number of Cores in Use by a Specific Task

$ ps -eo pcpu,args |grep 'python -u'|gawk '{if ($1 !~ /^0/) {print $1}}'
101
101
101

add |wc -l at the end

10. Memory in KB

cat /proc/meminfo |grep 'MemTotal' |gawk '{print $2}'

11. HDD/SSD size

sudo fdisk -l 2>/dev/null |grep -i 'Disk'|grep 'da' | gawk '{print $3,$4}'

12. HDD/SSD space available

df -H
