find

问题 I want to delete all files which have names containing a specific word, e.g. "car". So far, I came up with this: find|grep car How do I pass the output to rm? 回答1: find . -name '*car*' -exec rm -f {} \; or pass the output of your pipeline to xargs : find | grep car | xargs rm -f Note that these are very blunt tools, and you are likely to remove files that you did not intend to remove.

问题 Is there a way to check if an instance of a specific data type is present in a list / dictionary, without explicitly checking every element / key? I suspect the answer is no.

I would like to replace every question # in the Word document with the corresponding hyperlinked question in Column B of the spreadsheet. I tried to use the macro in the StackOverflow question Multiple find and replace in MS Word from a list in MS Excel, but I get the Run-time
