把文件里面的数据读出来赋值给变量怎么实现？文件里面每一行都是如下的格式：
[{"ID":"1","CameraId":"1333948582","PoolName":"Camera1","CameraCycle":"1","CameraType":"2","CameraCap":"999 GBytes"}]
[{"ID":"1","CameraId":"1333948582","PoolName":"Camera1","CameraCycle":"1","CameraType":"2","CameraCap":"999 GBytes"}]
[{"ID":"1","CameraId":"1333948582","PoolName":"Camera1","CameraCycle":"1","CameraType":"2","CameraCap":"999 GBytes"}]
[{"ID":"1","CameraId":"1333948582","PoolName":"Camera1","CameraCycle":"1","CameraType":"2","CameraCap":"999 GBytes"}]
现在我想把文档里面每行133948582这列的数据用shell读出来并赋值给我自定义的变量，怎么实现？有办法吗？我想可能要用到awk，但是小弟才疏学浅，不会整啊！

说说你想做什么吧

1. awk '{print substr($1,24,10)}' file |(read  var; echo $var)

复制代码

a=($(awk -F"," '{print $2}' urfile | awk -F":" '{print $2}'| sed 's/"//g'))
echo ${a[0]}
echo ${a[1]}
echo ${a[2]}
echo ${a[3]}
