Shell script to read the system running state

Recently in the study shell, eldest brother let write a read system configuration information script as practice and work acceptance, I wrote such a script, read the operating system, kernel, network card, CPU, memory, disk and other information, the purpose is to see the person at a glance can see the configuration of this machine and the current state of operation:

#!/bin/bash#get System Infomation (sys_time=$ (date + "%y-%m-%d%k:%m:%s") #os_version =$ (lsb_release-a | sed-n '/ Description/p ' | Awk-f ' [:] ' {print $} ' | Sed ' s/^[[:space:]]*//') os_version=$ (cat/etc/issue | grep Linux) kernel_release=$ (uname-r) netcard_num=$ (ifconfig-a | grep ETH | WC-L) echo "[Public_info]" echo-e "sys_time= $sys _time\t# system Time" ECHO-E "os_version= $os _version\t# Operating system version" ECHO-E " kernel-release= $kernel _release\t# kernel version "######## #NETCADE infomation######### #echo echo" [Netcard_info] "echo" netcard _num= $netcard _num "echo" #网卡名字 | ip| mac| Network Card Driver | Network card Speed | Network card send traffic (bytes) | Network card receive traffic (bytes) | nic Total traffic (bytes) "for ((n=0;n< $netcard _num;n++)) doreceive_byte=$ (CAT/ Proc/net/dev | grep eth$n | awk ' {print$2} ') send_byte=$ (Cat/proc/net/dev | grep eth$n | awk ' {print$10} ') echo "netcard_$ ((n+1)) =eth$n|$ (ifconfig eth$n | grep "inet addr" | awk ' {print$2} ' | Awk-f ' [:] ' {print$2} ') |$ (ifconfig-a | grep eth$n | awk ' {print$5} ') |$ (ethtool eth$n | grep speed | awk ' {print$2} ' | se d ' s/^[[:space:]]*//') |${receive_byte}|${send_bytei}|$ (($Receive _byte + $Send _byte)) "done######### #CPU infomation############# #cpu_phical_count =$ ( Cat/proc/cpuinfo | grep "Physical ID" | Sort | Uniq | wc-l) cpu_model=$ (cat/proc/cpuinfo | grep "model name" | uniq | awk-f ' [:] ' {print$2} ') cpu_core_num=$ (cat/proc/cpuinfo | grep Cores | Uniq | Awk-f ' [:] ' {print $} ' | Sed ' s/^[[:space:]]*//') cpu_process_num=$ (cat/proc/cpuinfo | grep process | wc-l) cpu_frequency=$ (Cat/proc/cpuinfo | grep Mhz|uniq | Awk-f ' [:] ' {print $} ' | Sed ' s/^[[:space:]]*//') cache_size=$ (Cat/proc/cpuinfo | grep "Cache size" | uniq | awk-f ' [:] ' {print$2} ') cpu_idle=$ (MPs Tat | grep all | awk ' {print$11} ') cpu_used=$ (mpstat | grep all | awk ' {print$3} ') Echoecho "[Cpu_info]" echo-e "cpu_model= $cpu _model\t# CPU model "ECHO-E" cpu_core_num= $cpu _core_num\t#cpu number of cores "ECHO-E" cpu_phical_count= $cpu _phical_count\t#cpu number "ECHO-E" cpu_ frequendy= $cpu _frequency\t# Frequency/single "ECHO-E" cache_size=${cache_size}* $cpu _process_num\t# Cache "ECHO-E" cpu_idle=${cpu_ idle}%\t# Idle Rate "echo -E "cpu_used=${cpu_used}%\t# usage" ########## #memeber info############## #echoecho "[Mem_info]" ECHO-E "mem_total=$ ( free-m | grep Mem | awk ' {print$2} ') \t# total Memory "ECHO-E" mem_used=$ (free-m | grep Buffers/cache | awk ' {print$3} ') \t# has been using "ECHO-E" mem_free=$ (free-m | grep Buffers/cache | awk ' {print$4} ') \t# can use "########## #hard info ################# #file_system_num =$ (df-ph | grep/| wc-l) Echoecho" [Hard_i NFO] "echo" file_system_num= $file _system_num "echo" #磁盘总容量 (unit m) | used capacity (in M) | available traffic (unit m) | used% (%) | mount Directory "DF-PM | grep/| awk ' {print$2 ' | $ "|" $4 "|" $ "|" $6} ' exit 0) >system_infomation.txt
