这是我要删除的内容:

,{"Id":66719222,"TimeStamp":"2017-08-29T16:35:13.263","Quantity":24.03098850,"Price":0.01379000,"Total":0.33138733,"FillType":"PARTIAL_FILL","OrderType":"SELL"},{"Id":66719221,"TimeStamp":"2017-08-29T16:35:13.013","Quantity":0.70000000,"Price":0.01379000,"Total":0.00965300,"FillType":"PARTIAL_FILL","OrderType":"SELL"},{"Id":66719220,"TimeStamp":"2017-08-29T16:35:12.623","Quantity":31.30579055,"Price":0.01379000,"Total":0.43170685,"FillType":"PARTIAL_FILL","OrderType":"BUY"},{"Id":66719219,"TimeStamp":"2017-08-29T16:35:12.623","Quantity":12.87144703,"Price":0.01378000,"Total":0.17736854,"FillType":"PARTIAL_FILL","OrderType":"BUY"}]}

]}

所以输出是

{"success":true,"message":"","result":[{"Id":66719299,"TimeStamp":"2017-08-29T16:35:35.937","Quantity":0.80122000,"Price":0.01379000,"Total":0.01104882,"FillType":"PARTIAL_FILL","OrderType":"SELL"},{"Id":66719283,"TimeStamp":"2017-08-29T16:35:32.36","Quantity":7.36427025,"Price":0.01379000,"Total":0.10155328,"FillType":"PARTIAL_FILL","OrderType":"SELL"}]}

如果有人能帮忙,谢谢你。

sed 's/,{"Id":66719222.*/]}/' filename

或者,如果您愿意牺牲清晰度,使命令缩短一个字符:

sed 's/,[^}]*66719222.*/]}/' filename

或者更粗略地说:

sed 's/.\{7\}66719222.*/]}/' filename

假设 file

sed 's/\(.*\),{"Id":66719222.*/\1\]}/' file

如果在bash中,为什么不直接使用bash呢

str='{"success":true,"message":"","result":[{"Id":66719299,"TimeStamp":"2017-08-29T16:35:35.937","Quantity":0.80122000,"Price":0.01379000,"Total":0.01104882,"FillType":"PARTIAL_FILL","OrderType":"SELL"},{"Id":66719283,"TimeStamp":"2017-08-29T16:35:32.36","Quantity":7.36427025,"Price":0.01379000,"Total":0.10155328,"FillType":"PARTIAL_FILL","OrderType":"SELL"},{"Id":66719222,"TimeStamp":"2017-08-29T16:35:13.263","Quantity":24.03098850,"Price":0.01379000,"Total":0.33138733,"FillType":"PARTIAL_FILL","OrderType":"SELL"},{"Id":66719221,"TimeStamp":"2017-08-29T16:35:13.013","Quantity":0.70000000,"Price":0.01379000,"Total":0.00965300,"FillType":"PARTIAL_FILL","OrderType":"SELL"},{"Id":66719220,"TimeStamp":"2017-08-29T16:35:12.623","Quantity":31.30579055,"Price":0.01379000,"Total":0.43170685,"FillType":"PARTIAL_FILL","OrderType":"BUY"},{"Id":66719219,"TimeStamp":"2017-08-29T16:35:12.623","Quantity":12.87144703,"Price":0.01378000,"Total":0.17736854,"FillType":"PARTIAL_FILL","OrderType":"BUY"}]}'

echo "${x%66719222*}66719222]}"
