SSH登录的时候显示一些实用信息

脚本如容如下:

lvse="33[32m"
zise="33[35m"
end="33[0m"
dmidestatus=$(rpm-qa|grepdmidecode|wc-l)
totalmemkb=$(cat/proc/meminfo|grep"MemTotal"|awk'{print$2}')
echo-e""${zise}"SystemDate:"${end}${lvse}$(date+"%F%T")${end}
echo-e""${zise}"SystemName:"${end}${lvse}$([-f/etc/redhat-release]&&cat/etc/redhat-release||uname-o)${end}
echo-e""${zise}"Systemmachine:"${end}${lvse}$(uname-m)${end}
echo-e""${zise}"Systemuptime:"${end}${lvse}$(uptime)${end}
if[$dmidestatus-eq1];thenecho-e""${zise}"SystemProduct:"${end}${lvse}$(dmidecode-ssystem-product-name)${end};fi
if[$dmidestatus-eq1];thenecho-e""${zise}"SystemSerial:"${end}${lvse}$(dmidecode-ssystem-serial-number)${end};fi
echo-e""${zise}"LoginUser:"${end}${lvse}$(whoami)${end}
echo-e""${zise}"LoginIP:"${end}${lvse}$(w|greppts|head-n1|awk'{print$3}')${end}
echo-e""${zise}"Cpu:"${end}${lvse}$(cat/proc/cpuinfo|grep"modelname"|tail-n1|awk-F":"'{print$2}'|sed'
s///g')
echo-e""${zise}"CpuCore:"${end}${lvse}$(cat/proc/cpuinfo|grep"modelname"|wc-l)${end}
echo-e""${zise}"CpuCount:"${end}${lvse}$(cat/proc/cpuinfo|grep"physicalid"|sort-u|wc-l)${end}
echo-e""${zise}"Memory:"${end}${lvse}$((totalmemkb/1000000))"GB"${end}
echo-e""${zise}"interface:"${end}${lvse}$(ipaddrshow|grepinet|egrep-v"lo$|:"|awk'{print$NF,":"$2}')${end}

把如上内容放入/etc/ssh/sshrc 文件 如果没有次文件 就新建,然后退出登录 重新登陆 显示如下:
