怎么把命令输出结果赋值给变量(已解决)
- font size decrease font size increase font size
- Print Email
我要把
awk '/eth0/{print $1 }' /proc/net/dev |sed 's/eth0://'
输出的结果赋值给变量 input
搞定了
input=$(awk '/eth0/{print $1 }' /proc/net/dev |sed 's/eth0://'
)
awk '/eth0/{print $1 }' /proc/net/dev |sed 's/eth0://'
不能用一个句子写出来?
awk -F "[: ]+" '/eth0/{print $3}' /proc/net/dev

我如何把1,2,3分别赋值给VAR1,VAR2,VAR3呢?
