如何使用bash脚本向配置文件中添加新的输入内容？

Question

我想用bash脚本从终端向配置文件添加新的输入。这是我试过的。

echo Hello, please add the new text here
read varname
sed -i "s/\<my-images=>/& $varname/" /home/myconfig
echo Image $varname has been added to the configuration. Thanks!!

homemyconfig有

id=1
max-mb=1000
my-images=customimage

而所需产出是

id=1
max-mb=1000
my-images=mynewtext customimage

所以mynewtext应该加在my-images=后面，怎么做？

问题出在你传递给 sed. 试试吧

sed -i "s/my-images=/&$varname /" /home/myconfig
