grep for text with wild card in between
提问by beatbreaker
I would like to grep something like ==> *.sh <==. But it doesn't work, I can grep everything up to .sh <==but not get the wild card to work.
我想 grep 类似的东西==> *.sh <==。但它不起作用，我可以grep一切，.sh <==但不能让通配符起作用。
What's the trick here?
这里有什么诀窍？

You need to grep for something like "==> .*\.sh <=="
你需要为类似的东西grep "==> .*\.sh <=="
The .*part matches any character for any length, the \.part matches a dot.
该.*部分匹配任何长度的任何字符，该\.部分匹配一个点。
