linux以操作系统命令hostname

调了好一会儿，记个笔记：

 

hostname `awk -F= '/PRETTY_NAME/{print $2}' /etc/os-release|sed -e 's/"//g' -e 's/ /-/g' -e 's/(.*)//g' -e 's/-$//g'`$(arch|sed -e 's/_/-/' -e 's/^/-/')
hostnamectl set-hostname `awk -F= '/PRETTY_NAME/{print $2}' /etc/os-release|sed -e 's/"//g' -e 's/ /-/g' -e 's/(.*)//g' -e 's/-$//g'`$(arch|sed -e 's/_/-/' -e 's/^/-/')
hostname

 抓取系统类型方式比较多样，以下略有调整变化

awk -F= '/PRETTY_NAME/{print $2}' /etc/os-release|sed -e 's/"//g' -e 's/(.*)//g' -e 's/-.*//g'|awk '{print $1$2$3}

awk -F= '/PRETTY_NAME/{print $2}' /etc/os-release|sed -e 's/"//g' -e 's/(.*)//g' -e 's/-.*//g'|sed -e 's/ /-/g'  -e 's/-$//g'

 

于是

hostname `awk -F= '/PRETTY_NAME/{print $2}' /etc/os-release|sed -e 's/"//g' -e 's/(.*)//g' -e 's/-.*//g'|sed -e 's/ /-/g'  -e 's/-$//g'`$(arch|sed -e 's/_/-/' -e 's/^/-/')
hostname

hostnamectl set-hostname `awk -F= '/PRETTY_NAME/{print $2}' /etc/os-release|sed -e 's/"//g' -e 's/(.*)//g' -e 's/-.*//g'|sed -e 's/ /-/g'  -e 's/-$//g'`$(arch|sed -e 's/_/-/' -e 's/^/-/')
cat /etc/hostname
