不好意思
这问题 我找很久了 还是找不到
问题是这样
假如我有一个文字档
例如:
I wanna leave my footprints on the sands of time Know
there was something that, and something that I left behind
When I leave this world, I'll leave no regrets Leave something to remember,
我想找这行出来
there was something that, and something that I left behind
我下的方式是
cat txt | grep -o "there * that"
这边* 我想要说可以是任意字串
但grep 任意字符 似乎不是用*
我google很久 有找到一个 \w*
可以表示任意一个字符
但这不符合我的需求
因为我不知道中间的任意字元会有几个
请问有人有好方法吗??
谢谢
